EDEC is an acronym that stands for Entity, Data, Entity Relationship (ER) Diagram and Constraints. This is a model used in database design that allows for efficient data manipulation. In this model, the Entity represents an object in a database, the Data attributes describe the properties of the Entity, and the ER diagram captures the relationships between different Entities. The Constraints describe the rules that the data must adhere to.
EDEC is most commonly used in relational databases. A relational database stores information in relational tables where information is organized into rows and columns. EDEC allows the user to visualize and manipulate the data in a way that the user desires.
Here are some examples of how EDEC can be used:
