Set of tables

A set of tables is a collection of structured data tables grouped together because they are related by topic, purpose, or dataset.

Each table in the set typically contains rows and columns, where:

Rows represent individual records or entries.

Columns represent attributes or variables describing those records.

General description

A set of tables is used to organize complex or large datasets into logical sections, making the information easier to store, compare, and analyze. Each table usually focuses on a specific aspect of a broader dataset while maintaining consistency in structure or identifiers so the tables can be linked or interpreted together.

Example

In a university database:

One table may store student details (names, IDs, courses).

Another may store grades (student ID, course, score).

Another may store course information (course ID, instructor, credits).

Together, these form a set of tables that collectively describe the academic system.
