Answer 1

The step-by-step mapping process from the given ER diagram results in a relational schema. This schema includes the identification of primary keys and foreign keys for each table.

Step-by-step explanation:

The step-by-step mapping process involves transforming entities, relationships, and attributes from the ER diagram into tables, columns, primary keys, and foreign keys in a relational schema. Each entity becomes a table, each attribute becomes a column, and each relationship becomes a foreign key.

Identifying Primary Keys: For each table, one or more attributes uniquely identifying each record become the primary key.

Identifying Foreign Keys: In tables associated with relationships, attributes referencing the primary key of another table become foreign keys.

The resulting relational schema provides a structured representation of the data model derived from the original ER diagram, facilitating efficient data organization and retrieval.
