Abstract

The invention provides a data access system, which comprises a user interface assembly unit, a data mapping assembly unit and a property access assembly unit, wherein the user interface assembly unit is used for sending an access request to the data mapping assembly unit during running of a window program, and receiving service data fed back by the property access assembly unit; the data mapping assembly unit is used for searching out a data mapping table of the window program according to the access request, wherein the data mapping table comprises mapping relations from user interface data to service data; and the property access assembly unit is used for acquiring service data needed to be displayed during running of the window program according to the mapping relations in the data mapping table, and feeding the service data back to the user interface assembly unit. The invention further provides a data access method. According to the technical scheme of the invention, a data access function can be performed between a user interface assembly and a service object assembly through data mapping description and an intermediate data mapping service assembly on the premise of not influencing a user interface design and a service object design.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data access system and a data access method. Background technique [0002] In the application system, especially in the MIS (Management Information Systems, management information system) system, its main task is to process the data, such as adding, modifying, deleting, querying and other operations, which involves data in the UI loading display issues. The traditional processing mode is that all functions are in unit software components, that is, interface functions and business functions are mixed in components without hierarchical separation. [0003] In a system designed using the model-view-control (MVC) pattern, the data mapping relationship between the model and the view is usually completely one-to-one, that is, each view will have a corresponding data model. Since a business object has multiple presentation views, it is necessary to design the corresponding...
