These are the following steps to be done for database optimization : 1. Maintaining proper indexing for required

tables in the db (don’t over do indexing ,it may also lead to lowering performance.)

3. Maintaining proper relation and association between models.

4. Fetch only when it is required and only what is required and reuse the fetched data from the db as much as possible.

5. Optimize the query by limiting the data fetched and fetch data in batches for large amount of data.
