Problems solved by technology

[0007] There are some ETL tools on the market that can extract classified data based on rules, but these tools cannot be directly combined with PDM business processes and interface display, and cannot achieve an integrated display effect

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] The operation steps in the product implementation process are as follows:

[0031] 1. Definition of basic data:

[0032] Definition of meta-attributes: You can define basic information such as the name of the meta-attribute, data type, whether the attribute is enabled or not; each meta-attribute has and only has a unique serial number as its primary key identifier stored in the database; for example image 3 interface shown.

[0033] Definition of meta-object class: each meta-object class contains multiple meta-attributes describing its characteristic properties. The relationship between meta-object classes and meta-attributes is an aggregation relationship. The aggregation relationship is also described on this interface, such as the editing method of meta attributes, display status, display alias, and whether it needs to be displayed on various business int...

Abstract

This invention relates to a method for showing screening and classification of a data set in a PDM system. This method is expanded based on a metadata model of the PDM system, shows screening and classification of the data set according to a custom rule in the manner of directory tree, and defines one or more meta-object class to participate the configuration rule of the directory tree. The method comprises the following steps: a, the directory tree for classifying the data and the data lists which meet the rule condition are collected; b, and directory nodes on the directory tree are divided into static directory trees and dynamic directory tree. By adopting the method, only based on the script rule configuration, the data can be located precisely without program compilation; and thus, the data is convenient to show, collect and track dynamically. The method quickly meets the requirements of the projects with various data types, reduces the implementation cost and shortens the project cycle.

Description

technical field [0001] The invention relates to a display method for screening and classifying data sets, in particular to a display method for screening and classifying data sets in a PDM system. Background technique [0002] In the existing PDM system, the display methods for screening and classifying data sets, one is to use a fixed tree structure to classify data sets, that is, directly according to the data characteristics of the meta-model, capture more common attributes as feature attributes to classify data sets Classification; the other requires secondary development and programming, and cannot be configured based on rules. [0003] Using a fixed tree structure to classify data sets cannot meet the individual needs of the project, the implementation workload is heavy, the solution has low versatility, and low reusability. [0004] Secondary development programming is adopted, and the cost of secondary development increases. A large number of secondary developments ...
