What is data modeling and design?
Data Modelling is the process of analyzing the data objects and their relationship to the other objects. Data Model is basically an architect’s building plan. It is a process of documenting complex software system design as in a diagram that can be easily understood.
Is data model and database model same?
A database model is a type of data model that determines the logical structure of a database. It fundamentally determines in which manner data can be stored, organized and manipulated. The most popular example of a database model is the relational model, which uses a table-based format.
What is data Modelling in database?

What is the different data model of the database and its use?
Types of database models Hierarchical database model. Relational model. Network model. Object-oriented database model.
What is data model define the different type of data models?

What do you mean by data modeling compare different data models?
Data modeling is the process of developing data model for the data to be stored in a Database. Logical data model defines the structure of the data elements and set the relationships between them. A Physical Data Model describes the database specific implementation of the data model.
What is data modeling Why is it important in database design?

What are the advantages of data modeling?
Data modeling allows organizations to spell out specific details and requirements for both the overall network of connected databases as well as the design of individual databases. With a clear visual overview, it’s much easier to identify any gaps or opportunities before the blueprints go into development.
What are the different data models in DBMS?
Some of the Data Models in DBMS are:
- Hierarchical Model.
- Network Model.
- Entity-Relationship Model.
- Relational Model.
- Object-Oriented Data Model.
- Object-Relational Data Model.
- Flat Data Model.
- Semi-Structured Data Model.

What is a database schema?
