 What is Data Model in Database?

In an organization, various departments handle different aspects of data management, including how data is accessed, stored, and utilized. To effectively manage and describe these processes, data models are created.

A data model in a database serves as the logical structure that provides a clear understanding of how the database is organized. It outlines the methods for accessing, updating, and storing data within the system, ensuring consistency and integrity across the organization.

There are different types of data models:- 

1) Record based logical model

1. Hierarchical Data Model
2. Relational Data Model
3. Network Data Model

2) Object based logical model

1.     Entity Relationship Model

For the organization's members, the data model defines how operations are conducted within the database. It acts like a blueprint, guiding the development and maintenance of the database and ensuring that everyone involved has a shared understanding of how data is structured and managed. This not only simplifies the management of the physical database for developers but also enhances communication among various stakeholders, leading to more efficient data handling and decision-making.
