After implementing an ERD, what does an entity transform into?

• A. Data Element
• B. Relationship
• C. Table
• D. View

Answer: (C)

When an entity is identified and defined in an Entity-Relationship Diagram (ERD), it ultimately transforms into a table in a relational database. This transformation is crucial because the primary purpose of an ERD is to model how data is organized and how different entities relate to one another. Each entity in the ERD represents a specific object or concept that holds data within the database. As tables in a relational database, entities are structured to contain rows and columns similar to the entities shown on the ERD. Each row typically represents a unique instance of the entity, while each column represents an attribute of that entity. This table structure allows for efficient organization, retrieval, and manipulation of data. Understanding this transformation is fundamental for anyone working with databases, as it illustrates the process by which abstract concepts represented in an ERD are implemented into a tangible data structure used for storing and managing information.
