About Index Objects |
An index is a sorted map of selected columns in a table or object. Therefore an index is similar to a table, and the columns in an index refer to the rows and columns of the associated table. By indexing columns frequently used in queries, you can improve data retrieval performance. An index can be either unique or non-unique.
A non-unique index often enables faster queries. Oracle8 supports a type of index called a bitmap index. A bitmap index uses a compressed bit-stream storage technique that allows very fast retrieval. The characteristics and usage of this database object are described in Oracle documentation. |
