Lets discuss about some best practices on Database Optimization which I normally used for other projects. Step 1: Apply proper indexing in the table columns in the database: Well, some could argue whether implementing proper indexing should be the first step in the performance optimization process for a database. But I would prefer applying indexing properly in the database in the first place. This will allow you to achieve the best possible performance in the quickest amount of time in a production system. Applying/creating indexes in the database will not require you to do any application modification, and thus will not require any build and deployment. Step 2: Create the appropriate covering indexes: It does, compared to the situation where no index is created on the foreign key column, in which case, a full table scan is done (scanning all related pages in the table to retrieve desired data). But still, there is further scope to improve this query. Step 3: Defragment indexes if fragmentation occurs: You created all the appropriate indexes in your tables. Or, may be, indexes are already there in your database tables. But you might not still get the desired good performance according to your expectations. There is a strong chance that index fragmentation has occurred. I would wait for your response to discuss in details. Not only this, it is important to check whether I will have to check for which case you need which End point and how you are expecting the response.
