Problems solved by technology

But there are the following deficiencies: (1) Insufficient objective evaluation ability, model evaluation is mainly oriented to the information model at the logical level, which is somewhat disconnected from the actual system realization, and can only be evaluated from the theoretical design level; in addition, model evaluation involves subjective indicators, and the evaluation process requires Relevant experts participate, and the evaluation score comes from the subjective scoring of experts. In practical applications, it does not have the objective evaluation ability of automatic analysis and automatic scoring.
(2) Model evaluation based on model-based high-level design, the evaluation results cannot reflect the actual application effect of the model in the IT system, and there will be problems that the model with better design effect is not necessarily applicable
(3) Lack of quantitative scoring rules for evaluation indicators, it is difficult to intuitively reflect the quality of the model, and the operability is low in practical applications

Embodiment 1

[0040] like figure 1 As shown, it is a schematic flowchart of the evaluation method of the data model provided by Embodiment 1 of the present invention, which may include the following steps:

[0041] S11. Based on the metadata structure of the data model to be evaluated, determine the association relationship between the various database tables included in the data model to be evaluated.

[0042] During specific implementation, the data model generally includes database tables, association relationships between tables, and table fields. The content described by the data model consists of three parts, namely data structure, data operation and data constraints. Data structure is used to describe the static characteristics of the system, including data type, content, nature and the connection between data, etc.; data operation is used to describe the dynamic characteristics of the system, including data insertion, modification, deletion and query, etc.; data constraints It is ...

Abstract

The invention discloses a data model evaluation method, device and equipment, and the method comprises the steps: determining the incidence relation between all database tables contained in a to-be-evaluated data model based on a metadata structure of the to-be-evaluated data model; according to the incidence relation between the database tables, determining theoretical design indexes of the database tables and static weight factors of the database tables respectively; according to the monitored access record of each database table, respectively determining a dynamic operation index of each database table, and determining a dynamic weight factor of each database table; and determining a comprehensive evaluation result of the to-be-evaluated data model according to the theoretical design index and the static weight factor of each database table and the dynamic operation index and the dynamic weight factor of each database table. According to the method provided by the invention, the theoretical design index and the dynamic operation index are combined to evaluate the to-be-evaluated data model, so that the obtained comprehensive evaluation result is more objective and is suitable for practical application.

Description

technical field [0001] The present invention relates to the technical field of IT business support, in particular to a data model evaluation method, device and equipment. Background technique [0002] The data model is the core and foundation of the IT system. In the database system, the data model is used to describe the structure and semantics of the database. The quality of the data model design directly affects the operation effect of the system. [0003] A data warehouse is a subject-oriented, integrated, relatively stable data collection that reflects historical changes and is used to support management decisions. The data warehouse stores analytical data and is mainly used to collect various data of the enterprise and perform online analysis and processing. [0004] In order to effectively support front-end query and analysis, data warehouse modeling usually adopts a layered modeling method, which is divided into basic data layer, summary layer, data mart layer and a...
