Indexes

Indexes are database structures that improve the speed of data retrieval operations, such as querying and sorting.

Without indexes, the database would have to scan every row in a table to find the requested data, which can be slow for large tables.

#How it works

Indexes are like a table of contents in a book, providing a quick reference to where data is located. They store a sorted list of values and pointers to the actual data rows.

#Advantages of Indexes

• Improved query performance: speeds up data retrieval operations.
• Efficient sorting: enhances sorting operations.
• Enforcement of Uniqueness: Enforces uniqueness constraints.
• Support for Joins: Facilitates efficient Joins operations.
