What is a schema in the context of a relational database?
The software used to manage and query a database
The largest table in a database that contains the most records
A tool used to input new data into the database
An outline that defines the structure and organization of data within the database
A schema in a relational database is an outline or blueprint that defines how data is organized, including the structure of tables, columns, and relationships. You can think of it like an architectural plan for a building, describing the rooms (tables), their characteristics such as size and shape (fields/columns), and how different parts of the building connect (constraints and keys).
