What is book index?

In the simplest terms, a book index is simply a key to locating information contained in a book. It is also known as back-of-the-book index, as it is mostly found at the end of the book. The index terms can be names, places, events, or any other terms related to your book content.

Are there any tools to identify missing indexes?

The tool you are talking about is called the Database Engine Tuning Advisor (DTA for short). It can take a number of inputs and give recommendations on things like missing indexes. It is worth noting, though, that these are just suggestions and careful consideration should be taken instead of blindly following DTA’s recommendations.

What happens when an index is used the first time?

When an index is used for the first time, a new row gets created in the dm_db_index_usage_stats DMV and subsequently updated every time an index is used. However, as with every DMV, the data present in dm_db_index_usage_stats contain only the data since the last SQL Server service restart (SQL Server service restart resets the data in the DMV).

Why are indexes so important in SQL Server?

SQL Server indexes are an excellent tool for improving the performance of SELECT queries, but at the same time, SQL Server indexes have negative effects on data updates. INSERT, UPDATE, and DELETE operations cause index updating and thus duplicating the data that already exists in the table.

When to look for missing indexes in SQL Server?

Execute the query against your database and any time the Index Advantage for a particular index is above 1000, start evaluating whether the particular index will be beneficial or not. Remember that like other DMVs, the information stored by the Missing Index DMV gets deleted when the SQL Server is restarted.
