Logical Schema

A logical schema is a blueprint that outlines how data is organized and structured in a database, independent of its physical storage. It defines the relationships between different data elements, such as tables and fields, and helps ensure that data is stored in a consistent and meaningful way. Think of it as a detailed plan for a building, showing how various rooms (data) are connected and function together, allowing for efficient access and management without focusing on the materials or tools used to construct it.
