Embodiment 1
[0022] Embodiment 1: For the purchase and warehousing business of a purchase business, construct its business data model according to the method of the present invention.
[0023] Before building a business data model, the definition of data fields, atoms and atomic entities, expression atom types, expression string rules, and expression operators must be completed in the system. in the table below.
[0024] Definition of data fields:
[0025]
[0026] Definitions of atoms and atomic entities:
[0027]
[0028] Definition of expression atomic type:
[0029]
[0030] The definition of the expression string rule, the expression string is composed of 1 to 6 character strings, and the 1 to 5 character strings are separated by ".":
[0031]
[0032] Definitions of expression operators:
[0033]
[0034] After the above content is defined in the system, then the method of the present invention is used to construct the business data model.
[0035] First of all, a...
Embodiment 2
[0050] Embodiment 2: For the picking business of a maintenance business, build its business model according to the method of the present invention, before building the business data model, the definition of the data field, the definition of the atom and the atomic entity, and the expression atom type must be completed in the system The definition of , the definition of the expression character string rule and the definition of the expression operator, the content of the definition is as listed in Embodiment 1. After the content is defined in the system, the method of the present invention is used to construct the business data model.
[0051]
[0052] First, according to the attributes of the picking business, build a picking and warehousing business model, and decompose it into "picking", "picking list number", "car pick-up note number", "date", "accessories", "quantity", The picking business model of the "unit price" and "amount" atomic entities.
[0053] Secondly, the ato...

Abstract
A method for building a data model with integrity based on a tree-shaped atomic model structure relates to the field of computers, in particular to computer managementinformation system service modeling technology. The method includes: firstly, completing definition of data domains, definition of atoms and atomic entities, definition of expression atom types, definition of expression character string rules and definition of expression operational characters in a system; secondly, decomposing atomic entities of a service model and building the service model according to service attributes; thirdly, listing and defining attributes of the decomposed atomic entities in the system according to rules of the data domain definition, the atom and atomic entity definition, the expression atom type definition, the expression character string definition and expression operational character definition; and lastly, building entity integrity, referential integrity and user-defined integrity of the service model.
Description
technical field [0001] The invention relates to the computer field, in particular to the business modeling technology of a computer managementinformation system. Background technique [0002] The patent application number is 201010222311.4, and the patent name is "Tree Atomic Model Structure and Method for Constructing Business Model Using the Structure". The technology disclosed in the Chinese patent uses . Encapsulate and support COM interface standards and web service interface standards. This patented technology has solved the problem of data modeling consistency in enterprise information systems, but it has not solved the problem of relationship mapping between logical models and relational database products and the problem of model integrity management. [0003] At present, there are three main data models supported in the databasesystem, which are Hierarchical Model, Network Model and Relational Model; among these three data models, the relational model is the most...
