Logical data modeling is an important step in the data modeling and design process. It focuses on designing the database schema and relationships based on the requirements and constraints identified during the conceptual data modeling phase.

In logical data modeling, we translate the conceptual data model into a format that can be implemented in a database management system (DBMS). This involves defining the tables, columns, data types, primary keys, foreign keys, and other constraints necessary for storing and retrieving the data.

Logical data modeling helps in ensuring data integrity and consistency in the database. It provides a clear understanding of the data structure and relationships, which facilitates effective data management and analysis.

In logical data modeling, the relationships between entities are defined through ___ and ___.

The correct answer is foreign keys and primary keys.

Foreign keys define the relationships between tables by referencing the primary key of another table. They ensure data integrity and maintain referential integrity between related tables.

Primary keys uniquely identify each record in a table. They ensure the uniqueness of records and provide a way to access and retrieve data efficiently.

By defining both foreign keys and primary keys, logical data modeling establishes the relationships and structure of the database, enabling efficient data retrieval and manipulation.
