Description

Operational Framework Interface Products and Module Code Conversion Products

The present invention relates to an improvement of a system development program, which can be applied to various programming languages. Currently, the invention is implemented in Java programming language Enterprise Edition (Java2Platform, Enterprises Edition, J2EE).

According to the known MDA (Model-DrivenArchitecture-Model-Driven Architecture) in the development process, the construction mode is divided into three stages, namely: CIM, PIM and PSM. Finally, programmers code according to the UML pattern produced in the PSM stage. First of all, in the CIM (ComputationIndependentModel-Computation Independent Model) stage, it focuses on the system environment and requirements, but does not involve the internal structure and operation details of the system, while in the PIM (PlatformIndependentModel-Platform Independent Model) stage, it focuses on the internal details of the system, But not the physical platform that implements the system. The UML schema constructed at this stage is platform independent. The PSM (PlatformSpecificModel-Platform Specific Model) stage focuses on the details of how the system is implemented on a specific physical platform. In other words, in general, platform-related components, such as JAVA or C++ components (codes, are generated from PIM information) ), and cooperate with the conventional MVC (Model-View-Controller: model layer-view layer-control layer) development architecture as the basis of the system development architecture. The development architecture can be divided into view layer (View), control layer ( Controller), business logic layer (BusinessLogic) and data access layer (DAO). The business logic layer (BusinessLogic) is generally used to process the request content. This layer will refer to the components generated by the PSM, the DAO layer, or other components required by business logic, and return the request results to the view layer through the control layer ( View), and then the view layer components process the form fields one by one.

With the known technology, because there is no more detailed specification, during development, for the convenience of processing, the induction of the same method that DAO should have is ignored. Even if there is, the method is not enough to use, such as statistical methods, or The query of the interval field must be written in the business logic layer or other categories, and the same method cannot be summarized in an upper-level category to provide the business logic layer for use, so that the business logic layer with the same operation process must also be used. Rewrite again and again. Even if there is an MDA development process, but without a job architecture interface to provide analysis and design developers to provide reference from the existing analysis and design, its spirit cannot be exerted.

Based on the above, in order to unify all the current architectures, it is necessary to develop a basic development architecture.

Based on the fact that in order to meet various requirements in development and accumulate development experience, a specific development architecture must be formulated for various requirements on the basic development architecture. This architecture is called functional architecture.

Through the accumulation and observation of development experience, the components in the framework can be obtained through the technology of converter (code generator) to shorten the development time.

This case is based on the core spirit of OMG'MDA (Model-Driven Architecture of the International Object Management Organization), that is, after the designer understands the business situation, he does not develop a model immediately, but firstly judges whether there is an existing model. ", and then go to "Converter" to generate components, and design the functional structure. After the test is completed, it is judged according to its scope of application (community) to decide whether to organize it into an operation framework interface for future system analysis, designers, and program development. People refer to and make circular improvements.

The molding method is provided by a system (module conversion system), that is, the client provides the molder with an operation interface of a network application program to input the model information, and the model information is transmitted to the system through the network, and the system The module framework converter is used to generate the module framework library according to the model information of the molder, so as to provide the molder to download, develop and test; or the system downloads the module framework converter to the client's web application, and uses Model information provided by the molder generates the module framework library.

By defining a basic framework (class inheritance framework) and the application programming interface (API) it provides, the application programming interface mainly includes: form information class, form field information class, and is defined by the form field information class. Provides a method to achieve the control of field permissions; a functional structure, mainly based on a business logic category, referring to the table information category (EIO), the form field information category (FIO), and the table information logic layer/category (EIOLogic The method provided by ) completes the framework of a common processing program, and organizes the documents to form a functional framework interface, and combines the application programming interface (API) and the functional framework interface to form an operation framework interface. Next, the concept of the so-called model and table is explained in an embodiment, and an example of the customer data table and its associated table is used to illustrate the application programming interface and related categories provided by the implementation of the infrastructure by the module architecture converter.

Please refer to the first picture: customer data correlation diagram, including Customer (customer) table, Sex (gender) table, Degree (educational education) table, CustomerAddr (customer address) table and Address (address) table, by observing the correlation of each table , Data fields and abstract thinking with the function of table data maintenance, can be summarized and classified into several types, for example: Sex table and Degree table can be one type, because the operation method of maintaining table data is similar or even the same; Address Tables are another type, because The operation method of maintaining table data must first create city/county data, then create township/town/district data, and then create road or street names; in a broader thinking, of course, Sex table, Degree table and Address table can also be regarded as The same type, however, requires a higher technical level to achieve; and the Customer form is another type, because it is associated with multiple forms and is associated with a one-to-many detail file (CustomerAddr), so the so-called model, That is, types classified by observation and by experience. Note: Think further, what is the model similar to Customer? Such as Employee (employee); what is the model similar to Address (address)? Such as Department (department).

Each model type has its data flow and maintenance operation characteristics, so different functional structures are required. A functional structure is described in detail and documented by UML (Unified Modeling Language), which can become the common process of the model. Architecture interface, that is, a functional architecture interface.

The so-called table, in addition to the table created by the general data definition language (DDL), can also be regarded as a collection of data, through the structured query language (SQL) in each table in a related way (innerjoin, outerjoin, crossjoin, etc. etc.) to obtain a result set, the table described below includes a single table and an associated result set.

In order to realize the above functional architecture interface, two parts are used as an illustration: one is the vertical part, namely the class inheritance architecture (please refer to the second figure: class inheritance architecture diagram), this architecture is the basic architecture, which provides the inheritance of each class in the development process The basis is that each category can be classified into categories according to the characteristics of its functions to form an inheritance structure, and finally the Model (model) is the parent category at the top level. The other is the horizontal part, that is, the functional architecture. The upper layer/superior category has been defined by the basic architecture, or the existing open source architecture is integrated, or it is developed by itself and improved with the known MVC architecture. Through the accumulation of development experience, the original DAO The improvement of the layer is the EIO layer, and provides the FIO layer and the EIOLogic layer, and combines the view layer components to make it a structure that can be improved cyclically (please refer to the third figure: the basic flow sequence diagram of the functional structure).

1. Class inheritance architecture: Model is the parent class at the top, followed by Module (module), EntityInformation (EIO), and FieldInformation (FIO) as its subclasses; followed by Operation (job/operation) as the child of Module category.

1. Form information category (EIO: EntityInformationObject): Enhance the access function of the conventional data access layer (DAO), which is used to process data query, maintenance, statistics and table field name, foreign key field associated value Take and organize the names of the same methods into a higher-level/upper-level category, so as to provide the lower-level category inheritance to implement the methods defined by EIO (please refer to the fourth figure: EIO and FIO inheritance structure diagram).

1.1. Query field (SKey): implements a collection of EIO query fields for the lower class, including the primary key and non-primary key defined by the table, and adds interval fields to cover most of the query fields in a single table. requirements, the corresponding category is SText (form query field value category).

2. Form field information category (FIO: FieldInformationObject): define a upper/upper-level category, which is used to process the conversion of table field data into form query fields and form fields, and a category with maintenance field validation and length information , and each field can display its form field type according to its associated field, so that the business logic layer can more easily control and obtain the required fields, thereby achieving the function of controlling field permissions.

3. Form query field value type (SText): used to define the access type for accessing the form query field value and the logical operator and comparison operator (=, !=, < and like, etc.) of the form query field , generally corresponding to the query field (SKey).

4. Operation (operation/operation) category, which is used to provide the function of converting a specific format string or webpage parameter value into an object, and is the basic category inherited by the business logic layer.

2. Functional Architecture: Mainly based on a business logic category, which inherits from the Operation category, and refers to the upper-level categories of the category inheritance structure, Form Information Category (EIO), Form Field Information Category (FIO), and Table Information Category Logic (EIOLogic) The provided method completes the structure of a common processing program, and encapsulates it for reuse (please refer to the third figure: the basic flow sequence diagram of the functional structure).

1. Form information logic layer/category (EIOLogic): It is used to subdivide and accumulate the data processing methods of the same procedures in business logic processing. ) and the form query field value type (SText), which makes it possible to encapsulate and reuse various data processing modes, transaction control methods, and message response methods from development experience.

In order to distinguish the different functions of each layer of the development inheritance architecture, it is divided into three parts, one is the core library, the second is the functional architecture library, and the third is the module architecture library (please refer to Figure 5: Development Library Architecture Diagram) , and use the module architecture converter to implement the methods of the upper/upper layer classes EIO and FIO defined in the infrastructure to shorten the development time.

1. Core library, including: Model (model), Module (module), EntityInformation (entity information), FieldInformation (field information) and other categories, which are the core categories of the infrastructure.

2. The functional framework library, including: Operation, various business logic (Bizlogic) categories and EIOLogic formed after cycle improvement.

3. The module framework library, through the module framework converter, according to the model information (such as table 1), the implementation of the application programming interface (such as table 4, table 5) - table information category, form field information category defined The upper-level method, the generated categories include: Entity (entity), EntitySText (entity form query field value category), EntityEIO (entity table information category), EntityFIO (entity form field information category) (Note: Entity ( Entity) is a high-level concept word, which generally corresponds to the table name. Taking the model information provided in Table 1 as an example, the generated categories are: Customer (customer), CustomerSText (customer form query field value category), CustomerEIO ( Customer form information type), CustomerFIO (customer form field information type), Sex, SexSText (gender form query field value type), SexEIO (gender form information type), SexFIO (gender form field information type), Degree (educational education ), DegreeSText (category of educational degree form query field value), DegreeEIO (category of educational degree form information), DegreeFIO (category of educational degree form field information).

Please refer to Table 1 for a model information, according to the table information provided in Figure 1: Customer Data Association Diagram and extend the form information to provide the converter to generate the module framework library.

1. When adding and modifying the maintenance field, different input fields are presented according to the definition of the type, and its proper value is presented according to whether it is related to other foreign keys in the table.

2. The query field, that is, the above-mentioned SKey, presents different input fields according to the definition of the type, and presents its proper value according to whether it is related to other foreign keys in the table.

3. The D/L column of the query field: D indicates that the field should be displayed as an interval field for query input; L indicates that the field will be accompanied by a logical field to form a logic with the next field judge.

4. Maintenance field verification: Check the correctness of field data based on this information in order to provide view components.

Through the above table and using the converter to generate the type of module framework library, take Customer as an example to illustrate, the following describes the more important properties, methods and execution results in the form of a table. Note: For the execution results, please refer to the first figure: the table data of the customer data of the customer data association diagram.

Customer: According to the name of the table and its field name, data form, primary key, foreign key and other information, it is generated through the converter. Note: The parameters that should be in the method are omitted for the convenience of description.

CustomerSText: Based on SKey (id, year, sex, createDate), and generated through a converter, it is used to access the value of the query field of the form. Note: 1. Age and creation date are interval fields, and form an attribute with from (from) and to (to) as prefixes respectively. 2. Age comes with a logical field, and it forms an attribute with Logical as the suffix.

CustomerEIO: It is generated by the converter according to the method defined by the upper-level/upper-level category, and based on the programming experience and the information of the field name, data form, primary key, foreign key, etc. Query the Customer table.

CustomerFIO: According to the method defined by the upper/upper-level category, and based on the programming experience and the information of the field name, data form, primary key, foreign key, etc. of the form provided in Table 1, it is generated through the converter to provide the Customer The field name and field input type of the form operation interface.

Note: After the above summary, EIO and FIO are formed into an application programming interface (the application programming interface is shown in Table 4 and Table 5), and a common process framework interface (ie functional framework interface) of the model is added to become the operation framework interface.

Taking a relational single table data maintenance operation situation and a functional framework, and taking the Customer module category generated by the Customer relational model as an example, the formation of a functional framework interface is described.

Relational single table data maintenance functional structure interface Note: This is an example of the basic interface, which will be improved cyclically based on the accumulation of experience.

1. Basic functions: 1. Data verification: Process verification according to the form verification information set in Table 1. 2. Field logic: omitted. 3. Business logic: omitted. 4. Sorting function: When clicking the name of each form field, it will be sorted alternately in ascending and descending order.

2. Operation function:

1. Please refer to Figure 6: Functional Architecture-Associative Single Table-Initialization and Query.

1.1 Initialization situation: The query field, function buttons (add, modify, delete, save) and form field name are displayed during initialization.

1.2 Query Context: Enter the query conditions, click [OK], and the data will be displayed below the table query field according to the query conditions, and a field with a checked field will be attached.

2 Please refer to Figure 7: Functional Architecture-Associative Single Table-Modify and Save.

2.1 Modify and save the context: Click [Modify], and convert the checked data into data with input type according to the modification function structure process for modification; after the modification is completed, click [Save], and the selected data will be checked. The data is updated according to the data saved in the functional structure process after modification, and the data is displayed on the operation interface.

3. Please refer to Figure 8: Functional Architecture-Associative Single Form-Add and Save.

3.1 Add and save context: After clicking [Add], according to the structure flow of the new function, in the first stroke, a blank field with an input type and associated with it is displayed for input; after the addition is completed , and click [Save] to update the selected data according to the data of the function framework process of saving after adding, and display the data on the operation interface.

4. Please refer to Figure 9: Functional Architecture - Relevant Single Table - Delete and Confirm. 4.1 Delete and confirm the situation, click [Delete], a re-confirmation message will be displayed, after clicking [OK], the selected data will be deleted and confirmed according to the functional structure process, the deletion of the deleted data will be completed, and the updated data will be displayed in the operation. on the interface.

The above is the basic description of a functional architecture interface, which can be based on this architecture and related models, and individually explained according to the special requirements of similar related models, and processed in parameter mode, accumulating most of the same special requirements and descriptions And become the expansion of the basic function, and make the function structure more perfect.

In other words, according to different association models, different functional framework interfaces are defined. For example, if a detail file (address) is still associated in the customer data table, the interface operation mode can be extended according to the function framework interface for maintaining the data in the relational single table. Or define a MD (Master-Detail: master file-detail file) functional framework interface with new thinking, but the functional framework interface of the address can be conceived as a hierarchical functional framework interface, and maintain the functional framework interface according to the relational single table data The way of forming, and become another functional framework interface.

The above are generally more static relational models. More specifically, there are dynamic data models such as trading transaction files, workflow files, etc. These data model tables are converted into a table through structured query language (SQL). The business logic layer of its functional architecture process needs to deal with multiple tables, which is also a transaction functional architecture interface according to the formation method of the relational single-table data maintenance function architecture interface (due to the EIO and FIO points of the model). Both provide the same method, and can implement a common handler architecture).

The above is only the preferred embodiment of the present invention, any category provides similar methods, but the names are different, or the method names are different, but the execution results are similar or the same, or equivalent changes made according to the scope of the patent application of the present invention and modifications, all should fall within the scope of the present invention.
