In this paper, the authors present performance improvement techniques for data retrieval from customized data warehouses for efficient querying and On-Line Analytical Processing (OLAP) in relation to efficient database and memory management. Different database management techniques, e.g. indexing, partitioning, etc. play vital role in efficient memory management. A comparison of data retrieval time for a particular query from a relational database as well as data warehouse database with and without indexing is performed. The authors show that the application of different database management techniques result faster query execution by reducing data retrieval time.
