Abstract

PROBLEM TO BE SOLVED: To provide an asset management system in which partial assets can be prevented from being missed, by enabling structured assets to be retrieved easily after storing the assets in a repository.SOLUTION: A first asset repository 91 stores assets which are software obtained as results of product development or documents created during the product development as they are. A second asset repository 92 stores assets which are distinguished in accordance with whether they can be utilized again as they are or they need customization for re-utilization. Retrieval means 94 retrieves a first asset element meeting at least a given search key from among first asset elements stored in the first asset repository 91 and, on the basis of corresponding relational information, retrieves a second asset element corresponding to the retrieved first asset element from among the second asset elements stored in the second asset repository 92.

Description

  The present invention relates to an asset management system, an asset management method, and a program capable of accumulating and searching for assets obtained as a result of system or software development, which can be used when developing other systems and software.

  When a system or software is developed, the software obtained as a result of the development or a part thereof, and the documents created during the development or a part thereof are repositories as assets that can be used for the development of other systems and software. Stored in Such an asset (software obtained as a result of development or a part thereof, and a document group created during development or a part thereof) may be referred to as a developed product.

  The simplest mode of storing such assets in the repository is a mode of storing assets as they are without being structured. For example, a file serving as an asset is stored as it is in a file system.

  Asset structuring is a distinction between assets that can be reused as they are in the development of other systems and software, and assets that need to be customized for reuse, and systematically organize those assets. It is to be.

  When developing systems and software similar to those already developed, assets obtained by past development may be reused as they are, or some of them may be customized and reused. Product line type development is known as a method for developing a new system or software by reusing assets in this way. In product line development, assets that are reused are called core assets, and core assets are stored in a repository and managed. A plurality of products (systems or software) having common characteristics are developed by reusing core assets. At this time, core assets are divided into assets that are common to multiple products and reused as they are in individual product development, and assets that are customized and reused in individual product development based on differences between products. Are organized and stored in the repository. The former asset (the asset that is reused as it is) is called the common part. The latter asset (an asset that is customized and reused for each product) is called a variable part. Such product line type development is described in Non-Patent Document 1, for example.

  As described above, the asset obtained as a result of development can be stored in the repository as an aspect of storing the asset as it is without being structured, for example, as in the case of product line type development. There is a mode in which assets are stored by performing some kind of structure so that they can be used easily.

  When assets (software or a part thereof and documents or a part of documents) obtained as a result of product development are stored in the repository as they are, it is difficult to reuse the asset and the asset does not function effectively when reused. There is a problem that there are cases. Systems and software have been developed to achieve a specific purpose. Therefore, when a new system or software is developed, when an existing system or software asset is reused, it is usually reused after some customization. However, if the assets stored in the repository are not structured, it is unclear which assets are customized and reused, and it is difficult to reuse the assets. Also, if similar system and software assets are accumulated as they are, a large amount of similar assets will be stored in the repository, making it unclear which asset should be reused and reusing assets. It becomes difficult to do.

  On the other hand, when assets are structured and stored in the repository, there is a problem that it is difficult to search the stored assets. Structured assets are suitable for reuse. However, in order to reuse an asset, it is necessary to retrieve and retrieve the asset. When the asset is structured, it is difficult to retrieve the asset without knowing how the asset is structured. In general, assets can be easily searched by keyword search if there is domain knowledge. However, for assets structured so that they can be used in common, it is not easy to search from domain knowledge, and how they are structured (for example, how the directory structure or file names are defined) Etc.) is necessary to search.

  In addition, when assets are structured and stored in a repository, there is a problem that assets that are not stored in the repository may occur. If it is assumed that structured assets are stored and only structured assets are accumulated in the repository, it takes time to structure the assets, resulting in assets that are left unstructured and not stored in the repository. There is a case. All assets are important because they are used as information indicating development history, as reference information for other developments, and are reused during development. However, if there is a restriction that it must be structured in order to be stored in the repository, some important assets will be lost without being stored in the repository.

  To provide an asset management system, an asset management method and a program capable of easily searching for assets after storing structured assets in a repository and preventing missing of some assets. Objective.

  The asset management system according to the present invention includes a first asset repository that directly stores an asset, which is a software obtained as a result of product development or a document created during product development, and can be reused as it is or customized when reused. Stored in the second asset repository, a second asset repository that stores assets that are distinguished by whether they are required, a first asset element that is an individual asset stored in the first asset repository, and Corresponding relationship information input means for inputting corresponding relationship information indicating a corresponding relationship with a second asset element that is an individual asset, and at least a first asset element that matches a given search key, The second asset element corresponding to the searched first asset element is retrieved from the first asset element stored in the second asset element based on the correspondence information. Characterized in that it comprises a retrieval means for retrieving from the second asset elements stored in the repository.

  In the asset management method according to the present invention, the first asset repository stores the asset that is the software obtained as a result of product development or the document created during product development as it is, and the second asset repository can be reused as it is. Are stored in the first asset repository and the second asset repository, which are individual assets stored in the first asset repository. Corresponding relationship information indicating the corresponding relationship with the second asset element, which is an individual asset, is input, and at least the first asset element that matches the given search key is stored in the first asset repository. The second asset element stored in the second asset repository is retrieved from the one asset element, and the second asset element corresponding to the retrieved first asset element is retrieved based on the correspondence relationship information. Characterized in that it searches the production elements.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Embodiment 1. FIG.
FIG. 1 is a block diagram illustrating an example of an asset management system according to the first embodiment of this invention. The asset management system according to the first embodiment includes a first asset repository 1, a bridge information repository 2, a second asset repository 3, a bridge definition unit 4, and a search unit 5.

  The first asset repository 1 is a repository for storing software or a part thereof obtained as a result of system or software development, and a group of documents created during development or a part thereof as they are. An asset stored in the first asset repository 1 is referred to as a first asset. Further, each first asset is referred to as a first asset element. Further, identification information is defined for each first asset element. Hereinafter, this identification information is referred to as first asset element identification information. The first asset element identification information may be determined, for example, by analyzing attributes attached to the first asset element and the first asset element itself. Typically, a file name or a class name may be used as the first asset element identification information, but other information may be used.

  Since each first asset element stored in the first asset repository 1 is an asset stored as a result of development, it can be searched by a keyword given by the user. Each first asset element can also be searched by the first asset element identification information.

  The process of storing each first asset element in the first asset repository 1 may be performed manually, for example. By storing the first asset element in the first asset repository 1, the first asset can be accumulated in the first asset repository 1.

  The second asset repository 3 is an asset (software or a part thereof and a group of documents created during development) obtained as a result of system or software development, and is a repository for storing structured assets. is there. An asset that is structured and stored in the second asset repository 3 is referred to as a second asset. Further, each second asset is referred to as a second asset element. Further, identification information is defined for each second asset element. Hereinafter, this identification information is referred to as second asset element identification information. The second asset element identification information may be determined, for example, by analyzing attributes attached to the second asset element and the second asset element itself. Typically, a file name or a class name may be used as the second asset element identification information, but other information may be used.

  Each second asset element can be searched by the second asset element identification information.

  Since each second asset element is structured, a second asset element that can be used as it is when developing a new product (that is, a second asset element corresponding to a common part) and a customization when developing a new product The second asset element (that is, the second asset element corresponding to the variable part) to be used in a clear manner is systematically organized and stored. When each second asset element is systematically stored, each second asset element is named according to a predetermined rule, or a directory structure for storing the second asset element is determined. That's fine. For example, analyze the common features (features) of products (systems and software) as a whole, and analyze the features that differ from product to product, and further subdivide each feature. Thus, a feature corresponding to the common portion and a feature corresponding to the variable portion are determined. Such an analysis can be performed using, for example, the feature model illustrated in FIG. FIG. 2 illustrates a case where analysis is performed on a mobile phone. The feature set as “essential” corresponds to the feature of the common portion, and the feature set as “selection” or “substitution” corresponds to the feature of the variable portion. Although FIG. 2 shows a hierarchy of features of the product line itself, a hierarchy as illustrated in FIG. 2 can also be defined for assets. As a result, for example, the lower common part and the lower variable part that form the upper common part can be defined, and the lower variable part that forms the upper common part according to a predetermined rule, A directory for storing individual second asset elements may be determined by storing in a directory below the directory corresponding to the section. Alternatively, according to a predetermined rule, the file name of each second asset element and the directory name of each directory storing the second asset element may be determined so that the hierarchical relationship between the common part and the variable part can be understood. . Note that this example is an example of asset structuring, and the asset may be structured by other methods.

  Moreover, the process of structuring and storing the asset in the second asset repository 3 as described above may be performed manually, for example. By storing the second asset element in the second asset repository 3, the second asset can be accumulated in the second asset repository 3.

  The assets are stored as they are in the first asset repository 1, but at this time, as a result of storing the assets as they are in the first asset repository 1, some of the assets are structured as a result. Also good. That is, some of the assets stored in the first asset repository 1 may be structured by chance.

  The bridge information repository 2 is a repository that stores bridge information. Here, the bridge information is information indicating a correspondence relationship between the first asset element stored in the first asset repository 1 and the second asset element stored in the second asset repository. That is, the bridge information can also be referred to as correspondence information.

  Specifically, the bridge information is information that associates the first asset element identification information with the second asset element identification information. The bridge information can be expressed as shown below, for example.

  Bridge information = <first asset element identification information, second asset element identification information> *

  In the above example, “*” means any repetition. “<,>” Represents a set of first asset element identification information and second asset element identification information having a correspondence relationship. In addition, the item described first in this set is called a first item, and the item described later is called a second item. First asset element identification information is described as the first item, and second asset element identification information is described as the second item.

  The bridge information is manually created and stored in the bridge information repository 2.

  The bridge definition unit 4 assists an administrator in creating bridge information and storing it in the bridge information repository 2. For example, the bridge definition unit 4 displays each first asset element stored in the first asset repository 1 and each second asset element stored in the second asset repository 3 according to the operation of the administrator. The administrator may determine the bridge information with reference to each first asset element and each second asset element. Then, bridge information is input to the bridge definition unit 4 from the administrator, and the bridge definition unit 4 may store the bridge information in the bridge information repository 2.

  The bridge definition means 4 includes a display device (not shown) for displaying each first asset element and each second asset, and an input device (not shown) to which the administrator's operation and bridge information from the administrator are input. And a CPU (not shown) for controlling them.

  The search means 5 searches a set of first asset elements that match the search key and a set of second asset elements corresponding to each first asset element based on the search key given by the user, Present to the user.

  The bridge definition unit 4 and the search unit 5 are realized by a CPU of a computer that operates according to an asset management program, for example. In this case, for example, a computer program storage device (not shown) may store the asset management program, and the CPU may read the program and operate as the bridge definition unit 4 and the search unit 5 according to the program.

  Further, the search means 5 may be provided with a display device (not shown) for displaying the search results. Further, the search means 5 may display the search results on a display device (not shown) included in the bridge definition means 4. Further, the search means 5 may receive a search key from a user terminal (not shown) connected via a communication network and display the search result on the user terminal.

  Further, the first asset repository 1, the bridge information repository 2, and the second asset repository 3 may be realized by the same storage device 10 as shown in FIG. Alternatively, the first asset repository 1, the bridge information repository 2, and the second asset repository 3 may be realized by separate storage devices.

Next, the operation will be described.
FIG. 3 is a flowchart showing an example of processing progress of the first embodiment of the present invention. The search means 5 is given a search key from the user (step A1). As the search key, for example, a keyword, a class name and a file name, or a part thereof is used. The manner in which the user inputs the search key to the search means 5 is not particularly limited. For example, a search key may be input to the search means 5 via an input device (not shown) such as a keyboard. Alternatively, a search key may be input to the search means 5 in another manner.

  Next, the search means 5 makes the set of search results of the first asset (hereinafter referred to as the first asset search result set) an empty set (step A2). Step A2 is a process of initializing the first asset search result set to an empty set.

  After step A2, the search means 5 uses the search key given in step A1 to select all the first asset elements that match the search key from the first asset elements stored in the first asset repository 1. And all the first asset elements obtained by the search are added to the first asset search result set (step A3). The search mode of step A3 may be a mode of specifying the first asset element including the keyword by, for example, full text search. Further, for example, a first asset element having a file name that matches the keyword may be searched. These are examples of search modes, and search may be performed in other modes.

  Next, the search means 5 determines whether or not the first asset search result set is an empty set (step A4). The fact that the first asset search result set is an empty set (Yes in step A4) means that no first asset element has been searched in step A3. In this case, the search means 5 presents to the user that there is no asset that matches the search key as a search result (step A5), and ends the process.

  In addition, what is necessary is just to display a search result on the display apparatus provided in the search means 5, when presenting a search result by step A5 and step A11, A16 mentioned later, for example. However, the display mode of the search result is not limited to the above example. For example, a mode in which a search key is received from a user terminal (not shown) connected via a communication network and the search result is displayed on the terminal may be used.

  When the first asset search result set is not an empty set (No in step A4), the search means 5 makes the set of bridge information search results (hereinafter referred to as bridge information search result set) an empty set (step A6). ). Step A6 is processing for initializing the bridge information search result set to an empty set.

  After step A6, the search means 5 selects one first asset element from the first asset search result set (step A7). Then, the search means 5 selects all the bridge information in which the first item is matched with the first asset element identification information of the first asset element selected in step A7 from the bridge information stored in the bridge information repository 2. And all the bridge information obtained by the search is added to the bridge information search result set (step A8).

  After step A8, the search means 5 determines whether all the first asset elements belonging to the first asset search result set have been selected in step A7 (step A9). If there is a first asset element that has not yet been selected in step A7 in the first asset search result set (No in step A9), the search means 5 repeats the processing after step A7.

  When all the first asset elements belonging to the first asset search result set have been selected (Yes in step A9), the search means 5 determines whether or not the bridge information search result set is an empty set (step A10). The fact that the bridge information search result set is an empty set (Yes in Step A10) means that there is no second asset element corresponding to the first asset element belonging to the first asset search result set. In this case, the search means 5 presents each first asset element belonging to the first asset search result set to the user as a search result (step A11), and ends the process.

  If the bridge information search result set is not an empty set (No in step A10), the search means 5 makes the set of search results of the second asset (hereinafter referred to as the second asset search result set) an empty set (step A12). Step A12 is a process of initializing the second asset search result set to an empty set.

  After step A12, the search means 5 selects one piece of bridge information from the bridge information search result set (step A13). Then, the search means 5 selects the second asset element identification information that matches the second item of the bridge information selected in step A13 from the second asset elements stored in the second asset repository 3. All the two asset elements are searched, and all the second asset elements obtained by the search are added to the second asset search result set (step A14).

  After step A14, the search means 5 determines whether all the bridge sets belonging to the bridge information search result set have been selected in step A13 (step A15). If there is bridge information not yet selected in Step A13 in the bridge information search result set (No in Step A15), the search means 5 repeats the processing after Step A13.

  When all the bridge information belonging to the bridge information search result set has been selected (Yes in step A15), the search means 5 uses the first asset element belonging to the first asset search result set and the second asset as the search result. Each second asset element belonging to the search result set is presented to the user (step A16), and the process ends.

  According to the present embodiment, by inputting a search key that is easy to understand for a user such as a keyword, not only the first asset element that can be searched from the search key but also the first asset element can be searched using the bridge information. The corresponding second asset element can be searched. Therefore, it is possible to easily search for assets that are structured and stored in the second asset repository. In addition, assets that are not structured and are not stored in the second asset repository 3 are stored in the first asset repository 1 as first asset elements, and the first asset element is also a search target. Can prevent a missing asset from being searched.

Embodiment 2. FIG.
FIG. 4 is a block diagram illustrating an example of an asset management system according to the second embodiment of this invention. Constituent elements similar to those in the first embodiment are denoted by the same reference numerals as those in FIG. 1, and detailed description thereof is omitted. The asset management system according to the second embodiment includes a first asset repository 1, a bridge information repository 2, a second asset repository 3, a bridge definition unit 4, and a search unit 20. In the present embodiment, the search means 20 includes a search control means 21, a first asset element search means 6, a bridge information search means 7, and a second asset element search means 8.

  The search control means 21 controls the first asset element search means 6, the bridge information search means 7, and the second asset element search means 8, and the first asset element corresponding to the search key given to the user. Or a set of second asset elements, or both. In some cases, the bridge information corresponding to the search key is searched.

  Further, the search control means 21 may be provided with a display device (not shown) for displaying the search results. Further, the search control means 21 may display the search results on a display device (not shown) included in the bridge definition means 4. Further, the search control means 21 may receive a search key from a user terminal (not shown) connected via a communication network and display the search result on the user terminal.

  The first asset element search means 6 searches the first asset repository 1 for a first asset element that matches the search key using a keyword or the like or the first asset element identification information as a search key.

  The bridge information search means 7 searches the bridge information repository 2 for bridge information using the first asset element identification information or the second asset element identification information as a search key.

  The second asset element search means 8 searches the second asset repository 3 for a second asset element that matches the search key, using the second asset element identification information as a search key.

  The bridge definition means 4 and the search means 20 (search control means 21, first asset element search means 6, bridge information search means 7 and second asset element search means 8) are executed by a CPU of a computer that operates in accordance with the asset management program, for example. Realized. In this case, for example, a computer program storage device (not shown) stores the asset management program, and the CPU reads the program, and in accordance with the program, the bridge definition means 4, the search control means 21, the first asset element search means 6, What is necessary is just to operate | move as the bridge information search means 7 and the 2nd asset element search means 8. Each of these means may be realized by separate units.

Next, the operation will be described.
In the present embodiment, any one of the first asset element, the bridge information, and the second asset element is used by independently using any one of the first asset element search means 6, the bridge information search means 7, and the second asset element search means 8. Only the search can be performed. Further, as will be described later, a search process corresponding to the search type designated by the user can also be performed.

  First, the operation when any one of the first asset element search means 6, the bridge information search means 7 and the second asset element search means 8 is used alone will be described.

  FIG. 5 is a flowchart showing an example of processing progress when the search control means 21 uses only the first asset element search means 6 alone. When the operation illustrated in FIG. 5 is executed, for example, the search control unit 21 is set in advance such that only the first asset element search unit 6 performs a search alone.

  When a search key is input to the search control means 21 by the user, the search control means 21 inputs the search key to the first asset element search means 6 (step B1). When only the first asset element search unit 6 is set to perform a search alone, for example, a keyword or the first asset element identification information is input from the user as a search key.

  Next, the first asset element search means 6 makes the set of search results of the first asset (first asset search result set) an empty set (step B2).

  Then, the first asset element search means 6 uses the search key input in step B1 to select the first asset element that matches the search key from the first asset elements stored in the first asset repository 1. All are searched, and all the first asset elements obtained by the search are added to the first asset search result set (step B3).

  Next, the first asset element search means 6 determines whether or not the first asset search result set is an empty set (step B4). If the first asset search result set is an empty set (Yes in step B4), the first asset element search means 6 notifies the search control means 21 that there is no first asset element that matches the search key as a search result. The search control means 21 notifies the user of the search result (step B5). If the first asset search result set is not an empty set (No in step B4), the first asset element search means 6 searches each first asset element belonging to the first asset search result set as a search result. 21, the search control means 21 presents each first asset element belonging to the first asset search result set to the user.

  Also in the second embodiment, when a search result is presented to the user, for example, the search result may be displayed on a display device provided in the search control means 21. However, the display mode of the search result is not limited to the above example. For example, a mode in which a search key is received from a user terminal (not shown) connected via a communication network and the search result is displayed on the terminal may be used.

  FIG. 6 is a flowchart showing an example of processing progress when the search control means 21 uses only the bridge information search means 7 alone. When the operation illustrated in FIG. 6 is executed, for example, the search control unit 21 is set in advance such that only the bridge information search unit 7 performs a search alone.

  If only the bridge information search means 7 is set to search alone, a search key and search key type information are input. In this case, the first asset element identification information or the second asset element identification information is input as a search key. The search key type information is information indicating whether the information that the user inputs as the search key is the first asset element identification information or the second asset element identification information.

  When the search key and the type information of the search key are input to the search control unit 21, the search control unit 21 inputs the search key and the type information of the search key to the bridge information search unit 7 (step C1). .

  Next, the bridge information search means 7 makes the set of bridge information search results (bridge information search result set) an empty set (step C2).

  Then, the bridge information search means 7 refers to the search key type information and determines whether the search key input in step C1 is the first asset element identification information or the second asset element identification information. Determine (step C3).

  When the search key is the first asset element identification information, the bridge information search means 7 matches the search key input in step C1 with the first item from the bridge information stored in the bridge information repository 2. All the bridge information is searched, and all the bridge information obtained by the search is added to the bridge information search result set (step C4).

  On the other hand, when the search key is the second asset request identification information, the bridge information search means 7 selects the second item from the bridge information stored in the bridge information repository 2 and the search key input in step C1. All matching bridge information is searched, and all bridge information obtained by the search is added to the bridge information search result set (step C5).

  After executing Step C4 or Step C5, the bridge information search means 7 determines whether or not the bridge information search result set is an empty set (Step C6). If the bridge information search result set is an empty set (Yes in step C6), the bridge information search means 7 notifies the search control means 21 that there is no bridge information that matches the search key as a search result, and performs search control. The means 21 presents the search result to the user (step C7). If the bridge information search result set is not an empty set (No in step C6), the bridge information search means 7 notifies the search control means 21 of each bridge information belonging to the bridge information search result set as a search result. The control means 21 presents each bridge information belonging to the bridge information search result set to the user.

  FIG. 7 is a flowchart showing an example of processing progress when the search control means 21 uses only the second asset element search means 8 alone. When the operation illustrated in FIG. 7 is executed, for example, the search control unit 21 is set in advance such that only the second asset element search unit 8 performs a search alone.

  When a search key is input to the search control means 21 by the user, the search control means 21 inputs the search key to the second asset element search means 8 (step D1). When the setting is made such that only the second asset element search means 8 performs a search alone, the second asset element identification information is input from the user as a search key.

  Next, the second asset element search means 8 makes the set of second asset search results (second asset search result set) an empty set (step D2).

  Then, the second asset element search means 8 uses the search key input in step D1 to select the second asset element that matches the search key from the second asset elements stored in the second asset repository 3. All are searched, and all the second asset elements obtained by the search are added to the second asset search result set (step D3).

  Next, the second asset element search means 8 determines whether or not the second asset search result set is an empty set (step D4). If the second asset search result set is an empty set (Yes in step D4), the second asset element search means 8 informs the search control means 21 that there is no second asset element that matches the search key as a search result. The search control means 21 notifies the user of the search result (step D5). When the second asset search result set is not an empty set (No in step D4), the second asset element search means 8 searches each second asset element belonging to the second asset search result set as a search result. 21, the search control means 21 presents each second asset element belonging to the second asset search result set to the user.

  Next, an operation when the asset management system of the present embodiment performs a search process according to the search type specified by the user will be described. Search types include “search for first asset from search key”, “search for first asset and second asset from search key”, “search for second asset from second asset element identification information” and “search for second asset from second asset element identification information”. There are four types of “search for second asset and first asset from second asset element identification information”. In “search for first asset from search key” and “search for first asset and second asset from search key”, keywords, first asset element identification information, and the like are used as search keys. 8 to 12 are flowcharts showing an example of processing progress when the search type is specified.

  First, the search type is input from the user to the search control means 21 (step E1). In step E1, any one of the above four types is input as a search type. Then, the search control means 21 determines which search type is input from the above four types (step E2).

  If the search control means 21 determines in step E2 that “search for the first asset from the search key” has been input as the search type (ie, has been designated), the search control means 21 performs the operation after step E3 (see FIG. 9). . That is, when it is determined that “search for the first asset from the search key” is designated and a search key (for example, a keyword or first asset element identification information) is input from the user (step E3), the search control means 21 uses the first asset element search means 6 to obtain a first asset search result set that matches the search key (step E4).

  In step E4, the search control means 21 may send the search key input by the user to the first asset element search means 6 and perform the same processing as steps B2 and B3 shown in FIG. And the 1st asset element search means 6 will perform the process similar to step B2, B3, and will notify each 1st asset element which belongs to the 1st asset search result set obtained as a result to the search control means 21. Good.

  The search control means 21 presents to the user each first asset element belonging to the first asset search result set obtained from the first asset element search means 6 by the above processing (step E5). When the first asset search result set is an empty set, the search control means 21 may present to the user that there is no first asset element that matches the search key.

  When the search control means 21 determines in step E2 that “search for the first asset and second asset from the search key” is designated as the search type, the search control means 21 performs the operation after step E6 (see FIG. 10). That is, it is determined that “search for first asset and second asset from search key” is designated, and when a search key (for example, a keyword or first asset element identification information) is input from the user (step E6). The search control means 21 uses the first asset element search means 6 to obtain a first asset search result set that matches the search key (step E7). The processes of the search control means 21 and the first asset element search means 6 in step E7 are the same as in step E4 (see FIG. 9).

  Next, the search control means 21 sequentially selects the first asset elements in the first asset search result set, and the bridge information search means 7 causes the first item to identify the first asset element of the selected first asset element. The bridge information that matches the information is searched to obtain a set of bridge information search results (step E8).

  In step E8, for example, processing may be performed as follows. For example, the search control means 21 causes the bridge information search means 7 to set the bridge information search result set to an empty set, and the bridge information search means 7 performs the same operation as in step C2 (see FIG. 6).

  Then, the search control means 21 selects one first asset element from the first asset search result set obtained in step E7. Then, the search control means 21 sends the first asset element identification information of the selected first asset element to the bridge information search means 7 together with the search key type information indicating the search by the first asset element identification information. Then, the bridge information search means 7 performs a search in the same manner as in step C4 (see FIG. 6) based on the type information of the search key and the first asset element identification information of the selected first asset element. Add bridge information to the bridge information search result set. The search control means 21 repeats the same processing until all the first asset elements in the first asset search result set have been selected, and when the above processing is completed for all the first asset elements, the bridge information search means 7 Request notification of the bridge information search result set. In response to this request, the bridge information search means 7 notifies the search control means 21 of each piece of bridge information belonging to the bridge information search result set obtained at that time.

  As a result, the search control means 21 can obtain a bridge information search result set.

  Next, the search control means 21 sequentially selects the bridge information in the bridge information search result set, and causes the second asset element search means 8 to search for the second asset element that matches the second item of the selected bridge information. Thus, a second asset search result set is obtained (step E9).

  In step E9, for example, processing may be performed as follows. For example, the search control means 21 causes the second asset element search means 8 to empty the second asset search result set, and the second asset element search means 8 performs the same operation as in step D2 (see FIG. 7). .

  Then, the search control means 21 selects one bridge information from the bridge information search result set obtained in step E8. Then, the search control means 21 sends the second asset element identification information corresponding to the second item of the selected bridge set to the second asset element search means 8. Then, the second asset element search means 8 performs a search in the same manner as in step D3 (see FIG. 7) based on the second asset element identification information, and adds the searched second asset element to the second asset search result set. To do. The search control means 21 repeats the same processing until all bridge information in the bridge information search result set has been selected, and when the above processing is completed for all bridge information, the second asset element search means 8 2 Request notification of asset search result set. In response to this request, the second asset element search means 8 notifies the search control means 21 of each second asset element belonging to the second asset search result set obtained at that time.

  As a result, the search control means 21 can obtain the second asset search result set.

  The search control means 21 presents each first asset element belonging to the first asset search result set obtained in step E7 and each second asset element belonging to the second asset search result set obtained in step E9 to the user ( Step E10). If the first asset search result set obtained in step E7 is an empty set, steps E8 and E9 are not performed, and it may be presented to the user that there is no first asset element that matches the search key. Further, if the second asset search result set obtained in step E9 is an empty set, only the first asset element obtained by the search is presented and the fact that the second asset element has not been retrieved is presented. Good.

  If the search control means 21 determines in step E2 that “search for the second asset from the second asset element identification information” is designated as the search type, the search control means 21 performs the operation after step E11 (see FIG. 11). That is, when it is determined that “search for the second asset from the second asset element identification information” is designated and the second asset element identification information is input from the user (step E11), the search control means 21 A second asset search result set that matches the second asset element identification information is obtained using the two asset element search means 8 (step E12).

  In step E12, the search control means 21 may send the second asset element identification information input by the user to the second asset element search means 8 and perform the same processing as steps D2 and D3 shown in FIG. . Then, the second asset element search means 8 performs the same process as steps D2 and D3, and notifies the search control means 21 of each second asset element belonging to the second asset search result set obtained as a result. Good.

  The search control means 21 presents each second asset element belonging to the second asset search result set obtained from the second asset element search means 8 by the above processing to the user (step E13). If the second asset search result set is an empty set, the search control means 21 may present to the user that there is no second asset element that matches the second asset element identification information.

  If the search control means 21 determines in step E2 that “search for the second asset and the first asset from the second asset element identification information” is designated as the search type, the search control means 21 performs the operation after step E14 (see FIG. 12). . That is, when it is determined that “search for the second asset and the first asset from the second asset element identification information” is designated and the user inputs the second asset element identification information (step E14), the search control means 21 uses the second asset element search means 8 to obtain a second asset search result set that matches the second asset element identification information (step E15). The processing of the search control means 21 and the second asset element search means 8 in step E15 is the same as that in step E12 (see FIG. 11).

  Next, the search control means 21 sequentially selects the second asset elements in the second asset search result set, and the bridge information search means 7 causes the second item to identify the second asset element of the selected second asset element. Bridge information that matches the information is searched to obtain a set of bridge information search results (step E16).

  In step E16, for example, the following process may be performed. For example, the search control means 21 causes the bridge information search means 7 to set the bridge information search result set to an empty set, and the bridge information search means 7 performs the same operation as in step C2 (see FIG. 6).

  Then, the search control means 21 selects one second asset element from the second asset search result set obtained in step E15. Then, the search control means 21 sends the second asset element identification information of the selected second asset element to the bridge information search means 7 together with the search key type information representing the search by the second asset element identification information. Then, the bridge information search means 7 performs a search in the same manner as in Step C5 (see FIG. 6) based on the type information of the search key and the second asset element identification information of the selected second asset element. Add bridge information to the bridge information search result set. The search control means 21 repeats the same processing until all the second asset elements in the second asset search result set have been selected, and when the above processing is completed for all the second asset elements, the bridge information search means 7 Request notification of the bridge information search result set. In response to this request, the bridge information search means 7 notifies the search control means 21 of each piece of bridge information belonging to the bridge information search result set obtained at that time.

  As a result, the search control means 21 can obtain a bridge information search result set.

  Next, the search control means 21 sequentially selects the bridge information in the bridge information search result set, and causes the first asset element search means 6 to search for the first asset element that matches the first item of the selected bridge information. Thus, a first asset search result set is obtained (step E17).

  In step E17, for example, processing may be performed as follows. For example, the search control means 21 causes the first asset element search means 6 to empty the first asset search result set, and the first asset element search means 6 performs the same operation as in step B2 (see FIG. 5). .

  Then, the search control means 21 selects one bridge information from the bridge information search result set obtained in step E16. Then, the search control means 21 sends the first asset element identification information corresponding to the first item of the selected bridge set to the first asset element search means 6. Then, the first asset element search means 6 performs a search in the same manner as in step B3 (see FIG. 5) based on the first asset element identification information, and adds the searched first asset element to the first asset search result set. To do. The search control means 21 repeats the same processing until all bridge information in the bridge information search result set has been selected, and when the above processing is completed for all bridge information, the first asset element search means 6 Request notification of one asset search result set. In response to this request, the first asset element search means 6 notifies the search control means 21 of the first asset element belonging to the first asset search result set obtained at that time.

  As a result, the search control means 21 can obtain the first asset search result set.

  The search control means 21 presents each second asset element belonging to the second asset search result set obtained in step E15 and each first asset element belonging to the first asset search result set obtained in step E17 to the user ( Step E18). If the second asset search result set obtained in step E15 is an empty set, the user is informed that there is no second asset element that matches the second asset element identification information without performing steps E16 and E17. do it. If the first asset search result set obtained in step E17 is an empty set, only the second asset element obtained by the search is presented and the fact that the first asset element has not been retrieved is presented. Good.

  Also in this embodiment, since the operations of Steps E6 to E10 are performed, the same effect as that of the first embodiment can be obtained. Furthermore, since the first asset repository 1, the bridge information repository 2, and the second asset repository 3 can be independently searched, various types of searches can be freely performed. Further, when the second asset element identification information is known, the first asset element corresponding to the second asset element can be searched, and the searched first asset element can be used as reference information. it can.

  Next, specific examples of the first asset and the second asset in the first embodiment and the second embodiment will be described. A typical example of the second asset is a core asset in product line development. In core assets, common parts and variable parts are distinguished and arranged. Each product is developed by reusing core assets. Therefore, the core asset in the product line development may be stored in the second asset repository 3 as the second asset. Then, each asset obtained when developing each product by product line development may be stored in the first asset repository 1 as a first asset. An example of the first asset and the second asset when the core asset is the second asset is shown in FIG.

  FIG. 14 shows an example of the first asset and the second asset in the case where a library in which classes are structured by patterning is used as the second asset.
