A tree structure basic data change recording method based on operator

Abstract

The invention discloses a tree structure basic data change recording method based on an operator, which comprising the steps of: dividing the change operation of the basic data into a plurality of atomic operation sets with a data node as a unit; determining an operation object and an operation result of each basic atomic operation, and obtaining a list of basic data change operators; according tothe basic data change request, extracting and combining the operators in the basic data change atomic operation list to obtain the basic data change operator expression; using the basic data changeoperator to change the basic data, generating a new version of the basic data and its number, and storing the changes and records of the basic data. The technical problem is solved that it is difficult to determine the historical evolution of the basic data and guarantee the data traceability after the basic data is updated in the prior art. The recorded basic atomic operation combination can be used for history tracing when the basic data is changed.

Description

technical field [0001] The invention belongs to the field of basic data management, and in particular relates to an operator-based tree structure basic data change recording method. Background technique [0002] Basic data and business data are a set of relative concepts common in various information management systems. Basic data is the data dictionary of the system. When the system is initialized, it exists in the system database and is a structural or functional support. ; while business data is in the process of system work, with the development of business work, the data related to business work is continuously added. Generally, basic personnel tables, organization tables, equipment catalogs (type tables), and material catalogs (type tables) can be regarded as basic data. The common feature in technology is that there are no foreign keys and no other tables will be referenced; while work The planning table, work process record table, work result record table, inspectio...

AI Technical Summary

Problems solved by technology

The method of the technical solution of the present invention aims at the situation in the prior art that it is difficult to determine the historical evolution of the basic data and the traceability of the data after the basic data is updated. By decomposing a basic data change operation into several basic atomic operations, an atomic The operation only changes the basic data node once, and records each basic atomic operation combination, so that the history can be traced by using the recorded basic atomic operation combination while realizing the basic data change
