Problems solved by technology

However, when new business and new requirements appear, training and specification also need to be followed up to standardize this new demand, so as to ensure that the entity-relationship models established based on the new business are similar. This standardization method has caused cumbersome work and cost increase
Therefore, it is necessary to solve the inconsistency of the data model of the same business caused by the construction of different entity relationship models by different system implementers, and provide a new model structure, which has a high degree of modeling consistency and effectiveness

Embodiment 2

[0035] Embodiment 2: Taking a procurement contract business as an example, first use the traditional entity relationship model to establish an information system business model for the contract, and then use the model structure of the present invention to construct. Among them, the contents of the procurement contract are listed in the following table:

[0036]

[0037] All underlined places in this contract are information that needs to be recorded in the information system; Party A in the contract is the company, and Party B is the supplier; both parties have a contact person, which means that for this contract, Representatives of both parties.

[0038] First, according to the description of the entity-relationship model, a corresponding information database is established. The information of the purchase contract includes the following contents:

Abstract

The invention discloses a tree atom model structure and a method for constructing a service model by using the tree atom model structure and relates to the field of computers, in particular to the technical field of data modeling of a computer management information system. The tree atom model structure is a model structure which is different from the conventional entity relationship model; and by using the model structure, data model structures which are established for the same service have consistency, and different data model structures cannot be generated. In the tree atom model structure, attributes are separated from relationships, a minimum attribute set is managed by using atoms, and the relationships are managed by using a tree structure. The tree atom model structure has high modeling consistency and solves the problem of inconsistency caused by description of the data models of the same service by using the entity relationship model.

Description

technical field [0001] The invention relates to the computer field, in particular to the technical field of computer management information system data modeling technology. Background technique [0002] In the process of developing information systems, the development of information systems from the perspective of data has now occupied the main position, and the essential characteristics of "data" in information systems have become the core content of current information system research. The commonly used entity-relationship model (ER model) divides data into entities and relationships. Entities describe the existence characteristics of the material in the objective world and the existence characteristics of human social organization and knowledge, and the characteristics are recognized from the perspective of a specific information system. A relationship is a mapping between one set of entities and another set of entities. [0003] When establishing an information system,...
