You are designing a conceptual model and are in the process of matching the DBMS requirements to the entity-relationship diagram (ERD) to create a data model that is software- independent. Which stage of the design phase are you doing? O a. internal schema O b. logical design O c. external model O d. physical independence
You are designing a conceptual model and are in the process of matching the DBMS requirements to the entity-relationship diagram (ERD) to create a data model that is software- independent. Which stage of the design phase are you doing? O a. internal schema O b. logical design O c. external model O d. physical independence
The design of a database is a critical step in creating an organized and efficient system for managing and accessing data. Among the phases of database design, the logical design stage is a pivotal point where the focus is on creating an abstract representation of the data model, independent of any specific database management system (DBMS). This phase involves the mapping of requirements and specifications onto an entity-relationship diagram (ERD), providing a high-level structure that can be adapted to various software environments. In this discussion, we explore the significance of the logical design phase and how it sets the foundation for a software-independent data model.
