Description

Domain asset information provision method and device {METHOD AND APPARATUS FOR PROVIDING INFORMATION ON DOMAIN ASSET}

The present invention relates to a method and apparatus for providing information on domain assets of a software product line.

With the recent development of electronic technology, the software industry has grown into a very large market. According to this market trend, when a user's needs (requirements) related to specific functions arise, the speed of software development to meet these needs has become a very important issue. In this respect, software product line engineering is drawing attention as part of a technology for rapid software development.

Software product line engineering is a software product line engineering that analyzes software to identify common and variable parts that make up it, and reuses all common parts and selectively reuses variable parts to quickly create similar software products that meet the needs of customers and markets. It says how to develop.

Software product line engineering can be largely divided into domain engineering and application engineering.

Domain engineering refers to the process of defining common and variable parts of the software product line and developing domain assets, which are reusable assets. Domain engineering can be subdivided by software development stage, and assets are created and managed by software development stage through each activity. Assets typically managed in domain engineering can include requirements, designs, implementation code, and test items. In each of these assets, in addition to the common part of the software product line, a variable point and variable information that can identify a part with variability are managed together.

Application engineering refers to the process of using domain assets to create new software products that actually run. In this case, the common part existing in the domain asset is reused for all software products, and the variable part is selectively reused according to the characteristics of the software product to be developed. In addition, some of the software products can be modified to add new features that are not reflected in the domain assets. In this way, all common parts existing in domain assets are reused, but by selectively reusing the variable parts, application engineering personnel can produce various software products more quickly and efficiently.

On the other hand, when a domain asset is required to be modified in software production line engineering, an influence may appear on an application area derived from the corresponding domain asset. Therefore, before modifying domain assets, domain engineering personnel need to perform an activity to analyze how much of the domain assets they want to modify affects the entire domain assets.

However, until now, there is no system that supports the decision-making of domain engineering personnel through analysis of the impact of modification of domain assets and visualization of the results.

1 shows a conceptual diagram of software product line engineering.

Referring to FIG. 1, an asset 10 of a domain asset in a software product line may include at least one category and an item included in each category. Here, the category may be a variation point, and the item may be variable information.

At least one of categories or items included in the asset 10 may be selectively combined by the design unit 20 to generate a level 30 constituting a domain asset. The level 30 may include, for example, a requirement level 31, a design level 32, an implementation code level 33, and a test level 34.

Each of the levels 30 may be composed of at least some of the items included in the asset 10. Accordingly, when a category or item included in the asset 10 is modified, the level 30 is also affected. Accordingly, when a category or item included in the asset 10 is modified, as a result, the area of the application generated to include the level 30 is also affected.

Therefore, if the category or item of the asset 10 needs to be modified, it is more accurate and more reliable if the impact of the modification on the level 30 or the area of the application is known before performing the modification. You will be able to produce software. In the following, domain asset information according to an embodiment of the present invention that identifies and provides information on at least part of the asset 10 when modification is made to at least a part of the asset 10 so that software can be produced more accurately and with high stability as described above is provided. The method and apparatus will be described in more detail.

Does not.

2 illustrates an example for explaining a method of providing domain asset information according to an embodiment of the present invention.

Referring to FIG. 2, a category of a domain asset may include Color, and an item belonging to the category may include Red, Green, and Blue. At this time, the item to be modified, the item to be edited, may be set to red.

The method of setting the correction item 1 is not specifically illustrated, but may be set based on obtaining an input from a user.

Levels of domain assets can include requirements level, design level, implementation code level, and test level. Each level can be composed of items having variability according to the identifier. The items included in each level may be preset values at the time of designing the domain asset, and are not limited thereto.

On the other hand, when an input for the revised item 1 is obtained, a direct related item related to the revised item 1 can be determined at each level. The direct related item may be an item that directly includes the modified item (1) among items of each level. For example, the directly related items may include the first item (2) to the fourth item (5).

When the directly related items at each level are determined, it is possible to identify whether the direct related items at the test level are related to other items. For example, in FIG. 2, the items directly related to the test level may be Test3 and Test4, and in the case of Test4, Red, which is the correction item (1), may be associated with an item called Green and an operator called or.

In other words, at the test level, the revised item (1) may include two items as directly related items. In this case, one item among the two directly related items, that is, the item having the identifier Test4, is the revised item (1 In addition to ), it may be related to other items (e.g., Green) (hereinafter,'other revision items'). In this way, an item that is not independent of the modified item 1 and is related may be referred to as an indirect related item.

When other modifications are made at the test level, at least one item containing different modifications at each level of the domain asset, i.e. at the requirements level, design level, implementation code level, and test level, is determined as an indirect related item. I can. For example, as shown in FIG. 2, when it is determined as another correction item (eg, Green) of the test level, the fifth item (6) to the eighth item (9) including the determined other correction items are indirectly related. Can be determined by items.

In some cases, in the case of Test4, which is an item related to both Red, which is a modified item, and Green, which is another modified item, at the test level, it may be changed from a direct related item to an indirect related item.

Meanwhile, in FIG. 2, an input obtained in relation to an item to be modified of a domain asset is described as a modification item 1, but the present invention is not limited thereto, and an input for a modification category may be obtained. In this case, items related to items included in the entire modified category may be determined as direct related items, and items related directly to the test level may be determined as indirect related items.

The input acquisition unit 110 may obtain an input for a modified item or a modified category of a domain asset. Specifically, the input acquisition unit 110 may obtain an input for a modification item or a modification category to be modified among domain assets from a user. For example, the input acquisition unit 110 may obtain an input for a value of a modified item, or a category to which the modified item belongs, that is, a value of a modified category and a value of the modified item.

The direct related item determination unit 120 may identify at least one item related to a modified item (or a modified category) among items included in each level constituting the domain asset. Here, the level constituting the domain asset may include, for example, a requirement level, a design level, an implementation code level, and a test level.

In some cases, the direct related item determination unit 120 may sequentially identify each of a requirement level, a design level, an implementation code level, and a test level to identify at least one item related to the modified item, regardless of the order. Can also be identified.

The direct related item determination unit 120 may determine each of the identified at least one item as a direct related item.

When the directly related items are determined for each level constituting the domain asset, the association determination unit 130 may identify whether there is an item related to another item among the direct related items of the test level. Specifically, the association determination unit 130 may determine whether the directly related item of the test level is related to a modification item (or modification category) different from the modification item (or modification category) of the domain asset.

Indirect related item determination unit 140, when the direct related items of the test level are related to other modified items, the related items of other modified items determined at each of the requirements level, design level, implementation code level, and test level are indirectly related items. Can be determined by

In some cases, the indirect related item determination unit 140 is determined as a direct related item at the test level, but may change the related item to an indirect related item by overlapping with the indirect related item.

The information providing unit 150 may provide information on direct related items and indirect related items. Specifically, the information providing unit 150 may analyze and provide the degree of influence of the directly related item or the degree of influence of the indirect related item. The provided information may include, for example, information in a visual form, and an example related thereto may refer to FIG. 5 or FIG. 6.

Referring to FIG. 4, the input acquisition unit 110 may acquire an input for a modified item or a modified category of a domain asset (S110). For example, if the input is an item called Red of a category called Color, the modified category may be Color, and the modified item may be Red.

The direct related item determination unit 120 may determine a direct related item at each of the requirements level, design level, implementation code level, and test level of the domain asset (S120). The direct related item may be a revised item or an item of each level including a revised category.

For example, when the revised item is Red, the directly related item determination unit 120 may determine an item including Red in each of the requirement level, design level, implementation code level, and test level as the directly related item.

In some cases, the direct related item determination unit 120 may determine whether the corrected item is sequentially included for each of the requirement level, the design level, the implementation code level, and the test level to determine the direct related item. However, the spirit of the present invention is not limited thereto, and a related item may be directly determined by determining whether to include a correction item for each level regardless of the order or at the same time.

The association determination unit 130 may determine whether the directly related item of the test level is related to another modification item or another modification category (S130). For example, the association determination unit 130 may determine whether a direct related item of the test level is related to an item other than Red, which is an item determined by input.

The indirect related item determination unit 140 may determine an indirect related item at each of a requirement level, a design level, an implementation code level, and a test level (S140). For example, when the item related to the directly related item Red is determined to be Green, the indirect related item determination unit 140 indirectly determines the item including Green at the requirement level, design level, implementation code level, and test level. Can be determined by related items.

In some cases, the indirect related item determination unit 130 determines whether other modified items are sequentially or conversely included for each of the requirements level, design level, implementation code level, and test level to determine indirect related items. I can. However, the spirit of the present invention is not limited thereto, and indirect related items may be determined regardless of the order or by determining whether correction items for each level are included at the same time.

In some cases, the indirect related item determination unit 140 is determined as a direct related item at the test level, but may change the related item to an indirect related item by overlapping with the indirect related item.

The information providing unit 150 may provide information on the directly related items and the indirect related items (S150). More specifically, the information providing unit 150 may calculate the degree of influence that the direct related items or indirect related items affect all items or each level. The information providing unit 150 may provide information by visually outputting at least one of the calculated influence of the directly related item and the calculated influence of the indirect related item.

In some cases, the information providing unit 150 separates the requirement level, design level, implementation code level, and test level, and separates direct and indirect related items from the rest of the items included in each level. It can be output visually.

In addition, in some cases, when receiving an input for selecting at least one of a requirement level, a design level, an implementation code level, and a test level, the information providing unit 150 divides the directly related items and indirect related items included in the selected level. It can be visually output.

However, the type of information provided by the information providing unit 150 is not limited to this example, and information on the degree of influence of the direct related items or indirect related items on the domain assets may be provided in various ways.

5 illustrates an example of information provided by an apparatus and method for providing domain asset information according to an embodiment of the present invention. Specifically, FIG. 5 shows the influence of each of the direct and indirect related items calculated in relation to FIG. 2.

Referring to FIG. 5, a direct influence degree and an indirect influence degree are calculated for each of a requirement level, a design level, an implementation code level, and a test level, so that visual information having the form of a table as shown in FIG. 5 may be provided.

The direct impact may be the ratio of the directly related items among the total items included in each level. The indirect impact may be the ratio of indirect related items among the total items included in each level.

Such an impact map may represent information on a direct or indirect impact of each level constituting a domain asset when an item determined as a modification item in a domain asset is modified. Accordingly, information on the risk or sensitivity that may occur when modifying a specific item in a domain asset can be provided. Therefore, the completion of software development can be further improved by making the item less influential to the modification having the same effect. I can.

6 illustrates another example of information provided by an apparatus and method for providing domain asset information according to an embodiment of the present invention.

Referring to FIG. 6, direct and indirect impact levels can be calculated for each of the requirements level, design level, implementation code level, and test level, and the calculated impact level can be provided as visual information in the form of a table. have. In this case, the direct impact, which is the degree of impact on the directly related items, and the indirect impact, which is the degree of impact on indirect related items, can be displayed separately.

More specifically, as shown in FIG. 6, a direct influence degree and an indirect influence degree may be divided into different patterns.

In some cases, when an input for selecting one of a requirement level, a design level, an implementation code level, and a test level is received, information on items included in the selected level may be provided as shown in FIG. 6. The information on the items included in the selected level may include direct related items of the selected level, indirect related items of the selected level, and other items.

In this case, direct related items and indirect related items may be displayed separately. Accordingly, the user can intuitively grasp the influence of the directly related items or the indirect related items on the modification of the domain asset.
