I created a professional ER diagram that reflects
Main entities of the system (such as Users, Books, Orders, etc.) Key attributes per entity Relationships between entities (1:1, 1:N, N:M) Referential integrity rules This model is the visual and logical foundation of the future database.
Creating the Data Dictionary
Document each entity and attribute with: Table and column name Data type Length Constraints (PK, FK, NOT NULL, etc.) Functional description The dictionary facilitates validation with the client and standardizes the design.
