A system of entity-attribute frameworks for information system modeling and data access

Abstract

A system of entity-attribute framework for information system modeling and data access, belonging to the field of information technology, including entity attribute modeling module, storage management module, process information management module, materialized view management module, extended query engine module, User UI module, see Figure 1. Among them, the entity attribute modeling module is responsible for the modeling function of the system. The advantage is that it can quickly model business objects and feed back to data storage, which improves the efficiency of system modeling, and data can be expanded in parallel with the increase of data volume, and users do not need to care about the structure and method of data storage , thereby reducing the complexity of the system; in terms of data access, it provides a method to expand the definition of column marks in SQL, and users can flexibly filter and sort data through the definition of column marks, which improves the flexibility of the system.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular provides a system of entity-attribute framework for information system modeling and data access. In this system, it is proposed to establish a unified description service through a combination framework of entity information and attribute information. The model's information structure and methods for handling the business model lifecycle. Background technique [0002] An information system is a system that collects, processes, stores, manages, retrieves, and transmits information. Common modeling methods for information systems include structured methods, object-oriented methods, prototype methods, process-based network modeling methods, and agent-oriented methods. . Among them, the object-oriented method emphasizes setting the objects in the analysis model for the objectively existing things in the problem domain, using the attributes and behaviors encapsulated in the obj...

Problems solved by technology

Object-oriented has played a huge role in the construction of information systems, but from the perspective of object-oriented system design, there are many types of objects, the relationship between objects is more complicated, and there are many interfaces between objects. When developing large-scale information systems, the system structure is very complicated. Developers have developed object-oriented software reuse technology, developed a large number of component libraries, advocated general interface technology, and lowered the threshold for building information systems, but there are still shortcomings. It is a difficult task to further abstract object-oriented and reduce the complexity of the system
