Abstract

The invention provides an information system data architecture model and a construction method thereof. Firstly, a system to be designed is decomposed into a plurality of businesses; each service is designed into a service data model composed of data entities, then a service function data model is constructed according to the angle of service operation, the data entities are defined through the service function data model, and finally one or more defined service function data models are constrained through a service process. According to the method, the system needing to be designed can be decomposed into a service data model; the service data model is decomposed into the data entities, on the basis, the user can construct the service function data model according to the functions, constraint is carried out through the service process, an independent function system is built, building of the function system is simpler, more convenient and more flexible, and the expandability and maintainability of the system are improved.

Description

technical field

[0001] The invention relates to the field of software technology, in particular to an information system data architecture model and a construction method thereof. Background technique

[0002] In the field of existing software development, the data structure description of the system is implemented in the software code, and the relationship with the code is tightly coupled. When maintaining and redeveloping the existing software, the programmer needs to The source code needs to be modified a lot before the software function can be changed, so the development efficiency is low and the cycle is long; moreover, most of the current software systems greatly increase the program due to software encryption, unmanned maintenance, and inability to obtain the source code. It is difficult for personnel to redevelop this type of software, which makes the life cycle of this type of software system very short. Contents of the invention

[0003] The purpose of the prese...
