File extension dbx information
A database index is a structure for data that enhances the operational speed on database tables. Creation of indices is achieved using columns in database tables to provide a basis for rapid lookups that are random as well as accessing ordered records efficiently. Storage of the index requires a typically less disk space in comparison to what the table requires. The main reason for the difference is that indices only contain key-fields regarding the table being arranged while excluding the other details of the table.

Some databases are capable of extending the indexing power by permitting creation of indices on expressions or functions. When using filtered indices, the creation of index entries is limited to the records that are capable of satisfying conditional expressions. Another aspect to flexibility is permitting indexing on functions that are user-defined and the expressions structured from assortments of functions that are built in. Indices can be non-unique or unique with the latter being a constraint by prevention of identical rows.
