ABSTRACT
The main purpose of undertaking this project is to circumvent some of the limitations implicit in the migration tools. The main constraint is the lack of facility to validate the migrated data at the target level. In case of small data transfer it may be possible to make comparisons visually between the source and the target. But during the transfer of large volumet rics there is likelihood of the loss of some data elements. Hence a robust validation procedure becomes inevitable to assure data integrity at the target level. Informatica, a migration tool, seems to suffer this desideratum, which is the main motivation for this project. The software developed is highly comprehensive and concise in tackling this vital problem. Usually the migration from different external source s are considered to be the needs and then loaded into the data ware house. While the data are getting populated in data ware house, validation is a sine quanon to bring about the "data rectitude". The reports generated from data ware house are primarily meant for the higher management to embark upon adroit decision in respect of the future growth of the organization. The acient on this work is to be minimizing the manual checking and to replace it with automatic validation.
