Description

Universal establishing and processing method for strong service object based on type metadata

Technical Field

The invention relates to the field of information system construction, in particular to a general establishing and processing method of a strong business object based on type metadata.

Background

Information systems often have a large number of strong business objects and business processes to support their applications in specific fields, and in the process of research and development of information systems, the work of creating and processing strong business objects, etc., is full of a large amount of repetitive labor, and can occupy most of research and development costs. The strong service object is a strong type dataset, the establishment of the strong service object is to add a mark to an existing or newly-established entity, define an attribute set of the entity and generate a strong service object. The entity is a collection of some kind of things, which can be concrete things or abstract concepts. And after the strong business object is established, processing the strong business object according to business logic.

In order to solve the above problems, the industry has originally adopted a policy of self-defining objects, a user can extend an attribute set of an entity, a database structure can be automatically updated along with the change of the attribute set, and differences between different database types can be shielded through the management of a data source. The method essentially takes the attribute set of an entity as an extended custom attribute, the custom attribute is only taken as a unit for reading and writing data, cannot be added with specific business meanings and basically does not participate in business logic, so that the extended attribute set has no great practical effect on processing strong business objects.

Then, in order to avoid representing the extended attribute set as only one field composed of character strings, a new architecture has emerged, which develops DAL (Data Access Layer) for different types of entities. The fields defined by user participation may also have their special meaning, rather than simply having the attributes defined by user participation as abstract fields to store field values, and therefore some business logic may be added to this basis to handle strong business objects. However, this method needs a plurality of DAOs (Data access objects) and service logic classes that are continuously extended, so that the development cost is high, the maintenance difficulty is high, and it is not possible to uniformly and efficiently process strong service objects.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.

As shown in fig. 1, a flow chart for implementing new logic for a newly created entity. It can be seen that when a strong business object is created, many attributes need to be defined repeatedly, including: new traffic type, attribute set, connection data source, association data source, ACTION, command provider, and Link page. Thus resulting in a large amount of repetitive and burdensome work.

As shown in fig. 2, is a diagram of a typed metadata system architecture.

The general idea of the strong service object general establishing and processing method based on the type metadata is based on the configuration of the type metadata, the entity attribute, the relation attribute, the data source connection, the data access layer, the ACTION and the UI configuration are integrated, the signal slot technology, the plug-in technology and the transverse cutting logic processing technology are combined, the strong service object is quickly established, the type is taken as the target to unify the general service logic, an entrance for customizing the service logic is reserved, and the strong service object can be quickly processed according to the service logic.

As shown in fig. 3, a flowchart of a method for generic creation and processing of a strong service object based on type metadata according to an embodiment of the present invention includes the steps of:

step 301, defining configuration attribute set and relationship configuration item of the new entity, including attribute set, representation name, display mode, sorting method and editing characteristic of each type.

At step 302, the information system adds an Attribute (flag) to the extended Attribute, and the information system finally programs the Attribute, regardless of the extended field of the extended Attribute itself.

Step 303, defining DALs of each type and corresponding connection data sources and type-associated data sources, where the data sources are configured with information such as corresponding database drive types and connection parameters. The DAL only corresponds to a data source that stores connection information for the database. The DAL layer mainly has the function of being responsible for accessing the database, namely, realizing operations such as query, insertion, update, deletion and the like on the data table. The database may be either a database within the information system or a database outside the information system.

And step 304, configuring various types of available operations for the ACTION configuration item, wherein the available operations comprise general command providers and corresponding slot functions, and the ACTION configuration item can realize customized logic beyond general processing by expanding new command providers and slot functions.

Step 305: and determining the category of the ACTION, wherein the information system can design a general response corresponding to the ACTION according to the category of the ACTION. And if the general response of the ACTION does not meet the service requirement of the specific object, responding by a newly expanded command provider. The category of the ACTION is determined by an enumeratable operation. The enumerable operations include: general creation, editing, deletion, addition, removal, expansion of detailed information, location marking, and track tracing.

Step 306, configuring various types of link pages for the UI configuration items, wherein the pages comprise: management page, inquiry page, detailed information page and associated object attribute page. Generally, a certain type of page has a property indicator, an editor integrating several editing parts, a data list, an attachment manager, and several associated object pages. The editor has a plurality of different editing input modes, including: editing the input directly, selecting the input from a number of alternatives, filling the input by the user, or selecting the input from the results of a sub-query. The editor may be extensible and its input modes may be enumerated. Even if a new input mode exists, the input mode can still be realized by expanding the editor. The editor framework can be applied whenever a new entity, an editing entity or a querying entity needs to fill in filter terms.

Step 307, automatically generating DALs (data access layers) for different database drivers according to the attribute configuration and the data source configuration, acquiring database driver information from the data source, and acquiring data model information from a DataModel (metadata model); by this point, sufficient information has been obtained to generate the DAL layer. And then, providing services for the outside by taking the type as a Key (Key value), such as creating a data table, updating a data table structure, executing data editing operation, executing various queries and the like. And establishing a new entity by using the DAL and the configuration Attribute set, the relationship configuration item, the Attribute, the DAL, the UI configuration item, the ACTION configuration item and the category. The strong business object can be quickly established according to the new entity.

Step 308, generating CRUD (Create Retrieve Update Delete, add, read query, update and Delete) service logic and interface operation entry of different types of strong service objects according to the ACTION configuration and the UI configuration. Although the information system cannot determine the types of the ACTIONs before the ACTION configuration is completed, and neither the usage scenarios (e.g., operation management, query, and link page) of the ACTIONs nor the objects of the specific ACTIONs can be determined, the types of the general ACTIONs can be enumerated and a default responder can be provided for each general ACTION, and each ACTION type can also expand its own special responder to process the ACTION with special requirements. In addition, the ACTION set at the time of management, the ACTION set at the time of query, and the ACTION set under the link page are separately defined for types, so that a toolbar above the management list, a toolbar above the query list, or a toolbar after a certain entity is selected or a context toolbar can be obtained by general logic. And if the general response of a certain ACTION does not meet the service requirement of a specific object, responding by a newly expanded command provider, otherwise, directly using the general response to generate the CRUD service logic. And according to the CRUD business logic, using the interface operation entry to realize the quick processing of the strong business object.

In summary, the general establishment and processing method for strong service objects based on type metadata provided by the present invention configures type metadata for strong service objects, integrates entity attributes, relationship attributes, data source connection, data access layer, ACTION, UI configuration, combines signal slot technology, plug-in technology and cross-cut logic processing technology, establishes strong service objects rapidly, unifies general service logic with types as targets and leaves an entry for customizing service logic, can realize rapid and efficient processing of strong service objects according to the service logic, and reduces workload of research and development and maintenance.
