The conceptual level is a high-level description of the data and its relationships in the database, without specifying how the data is physically stored or implemented. It defines the main entities, attributes, and constraints for the entire database, and is independent of any specific database management system or application. The conceptual level is also known as the logical level, and it is usually represented by an entity-relationship diagram (ERD).
