Table vs. View: Know the Difference
By Shumaila Saeed || Published on February 21, 2024
A Table is a database structure storing data in rows and columns; a View is a virtual table created by a query on one or more tables, presenting data without storing it physically.
Key Differences
In database management, a Table is a fundamental and physical structure with rows and columns to store data. A View, on the other hand, is a virtual table created through a query and does not store data physically but displays it as a table.

Tables are the basic storage unit in a database, holding actual data in a structured format. Views are like a lens over one or more tables, representing data from these tables in a specific way without duplicating it.

Creating a Table involves defining its schema, i.e., the structure of rows and columns, including data types. Creating a View involves writing a SQL query that pulls and presents data from tables, but the view itself does not hold this data physically.

Modifications to a Table, such as inserting, updating, or deleting records, affect the database's actual data. Modifications through a View, depending on its design, may or may not be possible, and when they are, they indirectly modify the underlying table data.

Tables are more about data storage and are integral to the design and functionality of a database. Views are used for data presentation and can simplify complex queries, provide security by limiting data access, and offer a customized view of the data.
