Career in Data Warehousing
Career in Data Warehousing
A Data Warehouse ( DW ) is a collection of technologies and techniques aimed at enabling the knowledge worker ( executive, manager, analyst, etc ) to make better and faster decisions using various analytical tools. It can be defined as ‘subject – oriented’, integrated, time – varying, non – volatile collections of data that is used primarily in organizational decision making.
Hence in general it can be considers as a power full tool for analytical processing. Nowadays, data Warehousing has become an important strategy in integrating heterogeneous information sources in organizations, and to enable Online Analytic Processing ( OLAP ) and Online Transaction Processing ( OLTP ). The DBMS based present day systems used for the data collection ( accumulation ), storage, retrieval and further processing, doesn’t seem to be completely credible, reliable and dependable.
When it comes to the areas of OLAP, OLTP, ad – hoc query processing data formatting and data cleaning, decision makers need some system which function beyond the capabilities of an ordinary Database Management Systems ( DBMS ). Hence it will be incorrect to see Data warehouse as a bigger form of DBMS or simple upgradation of DBMS.
There is limited number of people available who have worked with the full data Warehousing system project “Life Cycle”. In view of fast economic growth and industrial progress in our country and in the future we need more decision makers. Our small ( Small and Medium Enterprises – SME ) business organizations are growing to big organizations and to the level of Indian multinational companies.

To successfully complete the acquisitions or consolidation and to run the emerging big organizations, we need more data Warehousing professionals for analyzing the past and present data, and for making future prediction in the industry.
Such activities are called Business Intelligence ( BI ), which is a highly demanding IT application area in the industry. Banking, Insurance Health Care, Credit Card Service Providers, academicians, scientist and researchers are widely using data Warehousing and data mining technology for their various analytical activities. In view of the above and the proposed Indian banks consolidation and merging, Data Warehousing is going to generate lot of new opportunity for the IT professional, which are lying under utilised now.

The economic progress is accelerated the reverse brain drain process, which is going to accelerate the industrial sector further. It means that their will be an increased demand for data warehouse users, employees and professionals in the future.
