Abstract

The invention provides a system and a method for dynamically querying the inheritance data of a version. The system comprises a type creating unit, a database creating unit, a database view creating unit, a real-time processing unit and a query unit, wherein the type creating unit classifies a plurality of data objects according to a version inheritance relationship of the plurality of data objects to generate a plurality of data types; the database creating unit generates corresponding database tables for the data object of each data type, wherein the database tables comprise the version data of the data objects; the database view creating unit generates a database view according to the version inheritance relationship; the real-time processing unit changes the corresponding database tables in real time during editing of the data objects to change the corresponding database views in real time; and the query unit generates query sentences which correspond to the database views and acquires the corresponding data objects by operating the query sentences. By adoption of the technical scheme of the invention, the data query performance of the type having a parent-child relationship can be effectively improved, and difficulty in writing of a structured query language (SQL) character string program for query by a developer is reduced.

Description

technical field [0001] The invention relates to the technical field of data storage and query, in particular to a dynamic query system and method for version inheritance data. Background technique [0002] The present invention is oriented to design and manufacturing related enterprises and design units. When we talk about data models, everyone naturally thinks of model data and data tables. The usual data model is to abstract real data into objects, and then classify the objects and then summarize them. It is a type, and the type of storage is usually a data table. The data in the manufacturing industry is mainly product structure, parts, documents, process information, etc. After research and analysis, it is found that parts, documents, and file objects are the basic and smallest units. These three types of objects There are two types of features, version and status. In the range of status, the life cycle status is the basis. We usually establish two dimensions. The first ...
