Entity Relationship Model
The Entity Relationship model, also known as ER model, is a data model used to describe the relationships between different entities in a database. It visually represents how data is organized and the relationships between entities. The model consists of entities, attributes, and relationships, which help in understanding the structure of the database and how data is stored. Entities are objects or concepts that are represented in the database, attributes describe the properties of entities, and relationships define how entities are related to each other. The ER model is widely used in database design to create a blueprint for the database structure before implementation. It provides a clear and concise way to visualize the database schema and the connections between different data elements.
