What are the common database data models? In view of this problem, this article gives the corresponding analysis and answers, hoping to help more friends who want to solve this problem to find a more simple and feasible way.

At present, there are three common database data models: hierarchical model, mesh model and relational model.

Introduction of relevant knowledge points

The database model describes the methods of structuring and manipulating data in the database. The structural part of the model specifies how the data is described (such as trees, tables, etc.). The manipulation part of the model specifies the operations of adding, deleting, displaying, maintaining, printing, finding, selecting, sorting and updating data.

Classification of database models

1. Conceptual model

2. Hierarchical model

3. Mesh model

4. Relation model

5. Object-oriented model

In general, the expression of the model can be divided into physical model, mathematical model, structural model and simulation model.

About the common database data model to share here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
