b. logical structure
c. primary key
d. foreign key

Answer 1

In designing a relational database, the logical structure is defined by outlining the tables, fields, and relationships between tables using primary keys and foreign keys.

Step-by-step explanation:

To begin designing a relational database, one must define the logical structure by defining each table and the fields in it. The logical structure of a database involves creating a blueprint that represents the way data is stored, organized, and related within the database. It includes specifying tables, the columns (or fields) within those tables, data types for each field, and the relationships between tables, which are usually enforced through primary keys and foreign keys.

Primary keys are unique identifiers for the records within a table, ensuring that no duplicate records exist. Foreign keys are used to link records between different tables, establishing a referential integrity that maintains the accuracy and consistency of the data.
