Today, many tools and techniques have increased in the performance of database management as data warehousing and data mining. These warehouses provide storage functionality and responsiveness to queries beyond capacity of transaction oriented database. In this paper, the authors focus on indexing of the data warehouse and omits the requirement of significant manual intervention such as the data acquisition, data quality management, and functionality and performance optimization. Many approaches are used for data indexing such as sequential, B-tree key and some other advanced techniques.
