Schema vs. Table — What's the Difference?

A schema is a logical collection of database objects including tables, defining structure and relationships, while a table is a specific structure within a schema used to store data in rows and columns.

Key Differences
A schema in the context of databases represents a collection of database objects, such as tables, views, indexes, and stored procedures, that logically group these elements together. It defines how data is organized and how relationships between data are handled. In contrast, a table is one of the objects contained within a schema and is used specifically for storing data in an organized manner, with rows representing records and columns representing attributes of those records.
Schemas serve as a blueprint for a database, outlining the overall structure and the relationships between the different tables and other objects within the database. They provide a framework within which tables and other objects are created, ensuring data integrity and enforcing business rules through constraints and relationships. On the other hand, tables are the actual containers for data storage within this framework, holding the detailed records that are accessed and manipulated through SQL queries.
The concept of a schema allows for separation and organization of data within a database, especially in large databases where multiple users or applications might need to work with different sets of data. Schemas can help in managing access permissions, making it easier to control who has access to what data. Tables, while being integral parts of schemas, are focused more on the efficient storage, retrieval, and manipulation of data records.
In terms of database design, the schema is developed first to define the overall structure and relationships between objects. This includes planning out the tables, their columns, and the types of data that will be stored, as well as how tables relate to each other. The creation of tables follows, adhering to the schema’s design, to actually implement the storage of data according to the defined structure and rules.
The relationship between schemas and tables is akin to that between blueprints and rooms in a building's design. The schema provides the overall design and organization, indicating how different parts of the database (rooms) fit together, while tables are like individual rooms designed for specific purposes, in this case, storing data in a structured way.
