SQL Performance Tuning (in the Codebase): Indexes
SQL performance tuning can be an incredibly difficult task, particularly when working with large-scale data where even the most minor change can have a dramatic positive or negative impact on performance. But believe me, there are plenty of developers out there who have to perform DBA-like tasks. On top of that, corporate structure can also play a role. In basic terms, an index is a data structure that improves the speed of data retrieval operations on a database table by providing rapid random lookups and efficient access of ordered records. Indexes are also used to define a primary-key or unique index which will guarantee that no other columns have the same values.
