They are Logical Schema, Physical Schema and view Schema. Now let’s define them.
When someone thinks of this term as database schema, then we are addressing topics that concern a database system. In computer programming, a schema (pronounced SKEE-mah) represents the organization or structure for a database structure described in a formal language derived from the database management system (DBMS) and refers to the organizational structure of data to create a blueprint of how a database will be constructed. Typically, these are divided into database tables.
The formal definition of database schema is a set of formulas (sentences) called integrity constraints imposed on a database. These integrity constraints ensure compatibility between parts of the dataset. In this context, it represents the logical configuration of all or part of a relational database. It can exist both as a visual representation and as a set of formulas known as integrity constraints that set the rules of a database. These formulas are expressed in a data definition language, such as SQL. As part of a data dictionary, a database indicates how the entities that make up the database relate to one another, including tables, views, stored procedures, and more.
It is an outline, diagram, or data model. In computing, they are often used to describe the structure of different types of data. Two common examples include database and XML types.
