Solution
Entity Relationship Diagrams are output from the Conceptual Data Modeling phase of Database Development. This phase involves identifying the high-level, user-oriented entities and relationships that are relevant to the data requirements of the organization. The output of this phase is typically an Entity Relationship Diagram (ERD), which provides a visual representation of the main entities, attributes, and relationships within the system.
