DATABASE SUBSCHEMA Meaning and
Definition
-
A database subschema refers to a subset of a larger database schema that contains only relevant data and definitions needed to fulfill specific user requirements. It can be seen as a customized view of the database that focuses on a specific user's needs, tailored to their particular application or task.
In a database system, a schema represents the overall structure that defines the organization and relationships between various data elements, tables, and attributes. While the schema provides a global view of the database, a subschema offers a localized and customized view for a specific user or user group. It allows users to access and manipulate data without being overwhelmed by the entire database structure.
The database subschema contains the entities, relationships, and attributes that are relevant to a specific user's requirements. It may include only a subset of tables and data elements from the overall schema, hiding unnecessary or sensitive information from the user's view. The subschema is designed to provide a simplified and intuitive interface for users, presenting them with a logical and coherent representation of the data they need.
By creating database subschemas, database administrators can tailor the database system to meet the specific needs of diverse users or user groups. This allows for the customization of data access, manipulation, and presentation based on individual requirements, enhancing usability and efficiency.

Etymology of DATABASE SUBSCHEMA
The etymology of the word "database subschema" can be broken down as follows:
1. Database: The term "database" originated from the combination of "data" (plural of "datum", meaning information) and "base" (referring to a foundation or starting point). It was first used in the late 1960s to describe a structured collection of data organized for efficient retrieval and manipulation.
2. Subschema: "Subschema" is a compound word formed by combining the prefix "sub-" (meaning below, under, or secondary) and "schema" (derived from the Greek word "skhēma", meaning form or plan). In the context of databases, a subschema refers to a subset of a database schema that defines the logical view or representation of a portion of the overall database.
