What is Data Model?

A conceptual representation of data objects, relationships, and rules within a domain. It defines the structure, semantics, and constraints of data elements to facilitate understanding, communication, and implementation of data systems. Data models can be graphical or textual, illustrating entities, attributes, and their interconnections using diagrams or formal languages like Entity-Relationship (ER) or Unified Modelling Language (UML). They serve as blueprints for database design, software development, and data management processes, guiding the creation of databases, applications, and analytical frameworks. Data models help ensure data consistency, integrity, and interoperability across different systems and stakeholders.
