These information sources are dynamic in nature and keep on changing owing to the autonomous nature of transactions being carried out in the organization along with the complexity involved in gathering requirements from the users. Requirements elicitation and collection is difficult to perform because user needs keep on changing. As a consequence, the data warehouse must evolve so that it improves the data quality by easily incorporating the changes in requirements as well as source schema. In this paper we present a theoretical framework called DWEVOLVE to support data warehouse evolution. The proposed framework enhances the functionality of previously designed framework by taking into account the requirements specified by the users. Provisions have also been made to define and generate customized reports according to the user needs.<\/jats:p>","DOI":"10.1145\/2047414.2047433","type":"journal-article","created":{"date-parts":[[2011,11,21]],"date-time":"2011-11-21T19:54:36Z","timestamp":1321905276000},"page":"1-8","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["DWEVOLVE"],"prefix":"10.1145","volume":"36","author":[{"given":"Garima","family":"Thakur","sequence":"first","affiliation":[{"name":"Guru Gobind Singh Indraprastha University, Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anjana","family":"Gosain","sequence":"additional","affiliation":[{"name":"Guru Gobind Singh Indraprastha University, Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2011,11,14]]},"reference":[{"volume-title":"USA","year":"1994","author":"Inmon W.","key":"e_1_2_1_1_1"},{"volume-title":"Proceedings of the 5th National Conference; INDIACom-201","year":"2011","author":"Gupta V.","key":"e_1_2_1_2_1"},{"volume-title":"University of Bologna","year":"2009","author":"Golfarelli M.","key":"e_1_2_1_3_1"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/COMPSAC.2007.30"},{"key":"e_1_2_1_5_1","first-page":"249","volume-title":"A.
