What are some effective SQL database optimization techniques?

There are several techniques to optimize SQL databases, such as indexing, query optimization, and normalization. Would you like to know more about any specific technique?

Can you explain how indexing works?

Indexing creates a data structure that improves the speed of data retrieval operations on a database table. It works like an index in a book, allowing the database to find data without scanning every row.

What about query optimization?

Query optimization involves rewriting SQL queries to make them more efficient. This can include using joins instead of subqueries, selecting only necessary columns, and avoiding unnecessary calculations.

How does normalization help in optimization?

Normalization reduces data redundancy and improves data integrity by organizing tables and relationships. This can lead to more efficient queries and better performance.
