Description
Technical Field
The invention relates to the field of data processing, in particular to a data processing system and method based on an MVC model.
Background
Model View Controller (MVC) Model systems are generally composed of a Model module, a View module, and a control module, allowing for loose coupling among the various components that make up the system, to make program development more flexible, and to reduce repetitive code and enable code reuse, where:
the view module presents information representing model data and logical relationships and states to a user in a particular form, and the model module obtains display information that can be in a plurality of different display forms for the same information.
The control module is used for processing the interactive operation between the user and the software, and the responsibility of the control module is to control and provide the propagation of any change in the model module and ensure the corresponding relation between the user interface and the model module; the model module receives the input of a user, feeds the input back to the model module, further realizes the calculation control of the model module, and is a key component for enabling the model module and the view module to work coordinately.
The model module represents an enterprise database and business rules, and stores data required by the view module and the controller module; it encapsulates the computational relationships of core data, logic and functions of the problem, independent of specific interface expressions and I/O operations.
Fig. 1 shows a specific conventional MVC model, where a view module in the conventional MVC model sends a data receiving request to a control module according to a command sent by a client, the control module sends a data obtaining request to the model module according to the data receiving request sent by the view module, the model module sends data to the control module after receiving the data obtaining request sent by the control module, and the control module processes the data and sends the processed data to the view module for display. As can be seen from the above discussion, a large number of services such as all static and dynamic view modules, data storage, logic processing, and the like are completed by the control module, which easily causes the control module to be overstaffed, and has low post-maintenance efficiency and long data processing time; in addition, due to the problems of poor portability and the like among the existing MVCs, the development time is greatly increased.
In view of the above problems, how to overcome the above disadvantages is a technical problem that needs to be solved urgently in the field of digital processing technology.
