Data Model

A data model is an abstract representation of how data is structured, organized, and related in a system or database. It defines the entities, attributes, relationships, and constraints to ensure data integrity and support business processes. Data models serve as blueprints for database design, application development, and data analysis.

Also known as: Data Modeling, Data Schema, Entity-Relationship Model, ER Model, Data Structure Design

Why learn Data Model?

Developers should learn data modeling to design efficient databases, ensure data consistency, and facilitate communication between technical and non-technical stakeholders. It is essential for building scalable applications, performing data migrations, and implementing data governance in systems like relational databases, NoSQL databases, and data warehouses.
