1. Flat Data Model. Flat data model is the first and foremost introduced model and in this all the data used is kept in the same plane. Since it was used earlier this model was not so scientific.
2. Entity Relationship Data Model. Entity relationship model is based on the notion of the real world entities and their relationships. While formulating the real world scenario in to the database model an entity set is created and this model is dependent on two vital things and they are
3. Relational Data Model. Relational model is the most popular model and the most extensively used model. In this model the data can be stored in the tables and this storing is called as relation, the relations can be normalized and the normalized relation values are called atomic values.
4. Network Data Model. Network model has the entities which are organized in a graphical representation and some entities in the graph can be accessed through several paths.
5. Hierarchical Data Model. Hierarchical model has one parent entity with several children entity but at the top we should have only one entity called root.
6. Object oriented Data Model. Object oriented data model is one of the developed data model and this can hold the audio, video and graphic files. These consist of data piece and the methods which are the DBMS instructions.
7. Record base Data Model. Record base model is used to specify the overall structure of the database and in this there are many record types. Each record type has fixed no. of fields having the fixed length.
8. Object relation Data Model. Object relation model is a very powerful model but coming to it’s design it is quiet complex. This complexity is not problem because it gives efficient results and widespread with huge applications.
9. Semi structured Data Model. Semi structured data model is a self describing data model, in this the information that is normally associated with a scheme is contained within the data and this property is called as the self describing property.
10. Associative Data Model. Associative model has a division property, this divides the real world things about which data is to be recorded in two sorts i.e.
