    Study Notes

    Conceptual Design Phase in Data Modeling

    • The aim is to identify the overall structure and organization of the data, without considering the technical implementation details.

    Conceptual Model in Data Modeling

    • Primary focus is on the meaning and usability of the data, rather than its technical aspects.

    Conceptual Schema in Data Modeling

    • Provides a high-level, abstract representation of the data, focusing on the meaning and relationships of the data.

    Entity-Relationship (ER) Diagram in Database Design

    • The main purpose is to visually represent the relationships between entities in a database, and to organize the data in a logical and systematic way.

    Logical Model in Conceptual Data Modeling

    • Concerned with the transformation of the conceptual model into a more formal and technical representation, closer to the actual database implementation.
