What role does the Side Table play in a database or system?

A Side Table in a database or system is an auxiliary table that stores additional information related to the main table but not directly included in it.

It is used for:

• Storing metadata or extended attributes of objects.
• Separating frequently used and rarely used data for performance optimization.
• Organizing 'one-to-many' or 'many-to-many' relationships through separate tables.

For example, in a user application, the main table might contain basic data (ID, name, email), while the Side Table contains additional settings or activity history.

This approach helps to avoid redundancy and improves data structure.
