What involves specifying primary keys and analyzing relationships in a database?

Specifying primary keys and analyzing relationships in a database is a fundamental aspect of the database design and structure. This process falls under the category of organizing data into feature classes, where the focus is on defining how different data sets relate to one another and establishing unique identifiers for each data entry.

In this context, the primary key serves as a unique identifier for records in a database, ensuring that each entry can be distinctly referenced. Analyzing relationships involves understanding how different entities within the database interact with one another, which is crucial for proper data organization. This organization is essential for effective data retrieval and manipulation within the database, allowing users to efficiently query and manage the information.

The other options relate to different facets of database management, such as documenting design, creating views and indexes, and refining data integrity measures, but they do not directly address the foundational task of structuring data with appropriate keys and relationships. These tasks might enhance the database's functionality or ensure the data remains consistent, but they are not about the initial organization and framework of the database itself.
