Indexes are often intended to assist readers in quickly and easily locating information. They supplement the table of contents by allowing access to information by particular topic, while contents listings allow access to information by large divisions of the text organised in the order they appear in the text. When a database table is accessed, indexes are used to easily find data without having to check every row in the table. Indexes can be constructed using one or more columns from a database table, allowing for fast random lookups as well as easy access to ordered records.
