Consider the following database information:
domain s_id: integer domain grd: fixed length
character string length 1
STUDENT_GRADE(
Student_Number: s_id NOT NULL -
Grade: grd ) Primary Key -
Student_Number -
During which phase of the database design process would this information be developed?
This information would be developed during the logical phase of the database design process. In this phase, the conceptual model is translated into a formal representation that includes defining tables, attributes, primary keys, foreign keys, and other constraints. The goal is to achieve data normalization and ensure data integrity. The provided database information about domains, primary keys, and constraints aligns with the activities performed during the logical design phase.
The correct answer is A. Logical
Logical Design: In the logical design phase, the conceptual model is translated into a formal representation suitable for the selected database management system (DBMS). The designer creates a logical data model that defines the tables, attributes, primary keys, foreign keys, and other constraints. The main goal is to achieve data normalization to eliminate redundancy and ensure data integrity.
