Description

The invention relates to the field of power systems, in particular to a power neighborhood component retrieval method and a storage method thereof.
Background
Software reuse is an important field of software engineering and is considered as a main way to solve software crisis, improve software productivity and software quality, and enhance software openness and adaptability to external disturbances. Component-based software reuse is the focus of current software reuse research and is considered to be one of the key factors in achieving successful reuse. Component-based software reuse mainly involves 3 processes, i.e. the development of reusable components, the management of component libraries, which are links to the other 2 processes, and the building of component-based application systems, where there must be enough components to support the development. However, when a large number of reusable components are present, it becomes very difficult to find and select the appropriate component, and therefore an efficient search method must be used to enable the user to correctly locate the desired component.
Component retrieval has always been a key factor that restricts component reuse. If the retrieval efficiency is too low or the retrieved components are not suitable, software developers are often left with reusable components. At present, the retrieval method of the component mainly comprises the retrieval based on keywords, component facets and a knowledge base, and the methods have advantages and have certain limitations: retrieval based on component keywords: because there is an interaction phenomenon between keywords and there is a synonymy phenomenon of synonymy and synonymy between keyword terms, the effect of searching according to keywords is not ideal. Component facet-based retrieval: it is difficult to accurately describe the facets of all field members, and as the number of facets increases, it results in a reduction in search efficiency. Knowledge base based component retrieval: the retrieval method depends on the establishment rule and the perfection degree of a knowledge base, and is only stopped in theory at present.
The retrieval efficiency of the component is closely related to the storage mode of the component library, and if the structure of the component library has problems, no matter how efficient the matched algorithm is, good retrieval performance is difficult to obtain. Meanwhile, due to inherent differences among the domains, it is difficult to find a storage mode suitable for all the domain components.

Detailed Description
The invention provides a power neighborhood component retrieval method and a storage method thereof, solves the technical problems of limitation, unsatisfactory retrieval result and low retrieval efficiency of the conventional power neighborhood component retrieval method, and realizes the technical effects of improved retrieval efficiency and ideal retrieval result.
In order that the above objects, features and advantages of the present invention can be more clearly understood, the following detailed description of the present invention proceeds with further details. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflicting with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described and thus the scope of the present invention is not limited by the specific embodiments disclosed below.
The application provides a power neighborhood component retrieval method, which comprises the following steps:
(1) the data structure stored by the component is oriented to the data structure stored by the component in the power field according to the integration requirement of the power enterprise application system;
(2) establishing a component library facing the electric power field by utilizing an Oracle database, and directly storing component identification information and component characteristics in the database;
(3) storing the document information and the source code of the component in a file mode, and only storing the path information of the corresponding file in a database;
(4) according to the classification method for the components in the power field, the component category information in the component information identification codes is determined, and the component library is filtered according to the information, so that the retrieval range can be quickly reduced;
(5) determining a similar component set according to the characteristic combination of the components;
(6) and (5) carrying out search flat evaluation.
The data structure of the component storage expresses the storage format of the component in the component library system, and the definition of a proper component data structure is the premise for realizing effective component storage and retrieval. But at present, people often ignore the data structure stored by the component, which is an important reason that the existing component retrieval efficiency is not ideal. According to the requirement of power enterprise application system integration, the embodiment provides a data structure for component storage in the power field, and the problem of classification of components in the power field is solved. The data structure includes part identification information, part characteristics, part documentation information, and part source code, as shown in table 1,
TABLE 1 data Structure for Power Domain component storage
The identification information of the member is a code for identifying the member only in the member library, and reflects the classification condition of the member. The classification of components for each field is very complex, while the classification of components for a specific field (herein, taking the electric field as an example) has a certain rule, and the system is assembled by components corresponding to each related function. Therefore, it is suitable to adopt a classification method based on functional decomposition for the components of the power enterprise application system, and in this way, the component identification information is coded into 5 layers, namely a system layer, a subsystem layer, a sequence number and a version number from top to bottom. The system layer is used for indicating an integrated application system of which power company belongs, for example, ha indicates a wye-an power company; the subsystem layer is used for representing a relatively universal subsystem in the integrated application system, and comprises safety production management, electricity utilization management, scheduling management and the like, wherein dd represents scheduling management; the subsystem layer is used for representing specific items related to each subsystem, such as load prediction (fhyc) and fault analysis (gzfx) in scheduling management; component sequence numbers are used to denote the nth component of the same subsystem; component version numbers are used to denote different versions of components of the same sequence number. The classification method facilitates the retrieval of users and also simplifies the expansion of the component library facing the field.
The component characteristics describe information related to component management and intrinsic information of the component itself, and are divided into external characteristics and internal characteristics. The external features of the component comprise component type, keywords for describing the component, abstract (function for describing the component), developer, warehousing time, multiplexing times and the like, and are used for determining similar component sets in retrieval; the internal features are used to determine the most appropriate member in a set of similar members, including interfaces, development platforms, development languages, etc.
The method comprises the steps of establishing a component library facing the electric power field by utilizing an Oracle database, directly storing component identification information and component characteristics in the database, storing document information and source codes of components in a file mode, and only storing path information of corresponding files in the database. Therefore, the establishment and maintenance of the component library are facilitated, and the maintenance of the component document information and the source code only needs to operate the corresponding file.
According to a component storage mode, an Oracle database is utilized to establish a component library facing to the power field, and the designed verified components are added into the component library. For example, in the process of integrating the dispatching management subsystem, in order to search a Component for completing harmonic analysis in the Huaian power company dispatching management subsystem fault analysis subsystem, according to a two-step search method, firstly listing a search formula 'haddzfx', and carrying out fuzzy query in a Component _ distribution table for storing Component description information in a Component library, wherein select from Component _ distribution _ coherent _ Code 'ddgzfx' Component _ Code is a Component identification information field). By this step, the search range is greatly reduced. Then according to the characteristics of the components, the query author is Li Ming, and the query author is warehoused after 11 months and 1 day 2003, and the components of harmonic analysis are included in the abstract. And after the retrieval result is obtained, multiplexing can be performed.
For a component library with few components, the required components can be obtained by querying through a two-step retrieval method. However, with the increasing of component libraries, only similar component sets can be obtained through a two-step search method, which requires evaluation of search results. Evaluation does not simply utilize an input sample and a corresponding output sample of a component and compare it with the output of the desired component to determine if it is the desired component. Although the required components can be found, the method takes long time and is low in efficiency, and the evaluation process is quite complicated. In order to perform efficient search evaluation, samples of the test member are divided into positive samples and negative samples, and stored in test cases. The front surface sample refers to an input sample of the component when the component is executed, and then an output sample of the component is obtained, and such input-output pair is called as the front surface sample; otherwise, the reverse example is used. The similar component set is evaluated by utilizing the positive and negative samples of the components, and the components do not need to be actually executed in the evaluation process, so that the efficiency of retrieval evaluation is greatly improved.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiments according to the technical spirit of the present invention are included in the scope of the present invention.

(3) the document information and the source code of the component are stored in a file mode, and only the path information of the corresponding file is stored in the database.
