What is data model?
In computer science, data modeling is the process of creating a data model by applying a data model theory to create a data model instance. A data model theory is a formal data model description.For the source and more detailed information concerning your request, click on the related links section (Answers.com) indicated below.
What is the difference between data model and database model?
A database is a collection of tables that is used for some purpose (typically an application of some sort). A database model is a description of that database, and describes how the tables relate to each other. Typically, a model is designed first, then the actual database is implemented using the model as a blueprint.

Explain entity relationship model with suitable example?
An entity relationship model is a visual representation of the relationships between entities in a database. For example, in a university database, you could have entities such as "Student," "Course," and "Instructor," with relationships like "Student enrolls in Course" and "Instructor teaches Course." These relationships are represented by lines connecting the entities in a diagram, showing how they are connected and interact with each other.
What is the lowest data model?
The lowest data model is the physical data model. It represents how data is stored on a specific type of hardware and helps optimize storage and retrieval. It is the closest to the physical implementation in a database system.

What is a record-based data model?
-> A record based data model is used to specify the overall logical structure of the database.-> In this model the database consists of a no. of fixed formats of different types.-> Each record type defines a fixed no. of fields having a fixed length.-> There are 3 principle types of record based data model. They are :1. Hierarchical data model.2. Network data model.3. Relational data model.
