INTERNAL SCHEMA Meaning and
Definition
-
Internal schema refers to the way data is organized and structured within a database management system (DBMS). It defines how data is stored, the relationships between different data elements, and the format in which it is represented. The internal schema is primarily concerned with the physical aspects and implementation details of a database.
The internal schema provides a low-level view of the database and specifies how the data is stored on the secondary storage devices such as disks or tapes. It includes details such as the file organization, indexing techniques, data compression methods, and data storage formats. This level of schema focuses on optimizing the storage, retrieval, and manipulation of data for efficient performance of the DBMS.
The internal schema is typically designed by database administrators and system developers, as it involves decisions regarding the physical storage and access paths to the data. It acts as a bridge between the conceptual schema (which defines the overall structure of the database) and the physical storage devices.
Changes made to the internal schema do not affect how users interact with the database at the conceptual or external level. It provides a layer of abstraction between the physical storage implementation and the logical representation of data. This allows for modifications and improvements to the internal schema without impacting the applications or users relying on the database.

Etymology of INTERNAL SCHEMA
The word "internal" derives from the Latin word "internus", meaning "within", "on the inside", or "interior". It came into Middle English from the Old French word "interne", referring to something inside or within. The term "schema" has its roots in the Greek word "σχῆμα" (skhēma), which means "shape", "figure", or "form". In psychology and cognitive science, a "schema" refers to an organized pattern of thought or mental framework. When combined, the term "internal schema" refers to an individual's internalized mental structure or organizing framework for interpreting and understanding information.
