About
Welcome to Sandesh Gawande’s website on data warehousing. This website includes wealth of knowledge critical to the role of Enterprise Data Integration Architecture. ETLGuru has been designed for sharing upto date information on Data Integration, ETL and Data Warehousing. Sandesh (Creator of this site) is highly experienced in this field. This portal will share information on ETL, so that Developers, Managers, Architects can have a reliable, usable and impartial source of information.
Why etlguru.com exists? Sandesh started as a Data Architect for OLTP applications. But as he transitioned to Business Intelligence environment, over a period of time he realized that data integration or ETL is seventy to eighty percent of data warehousing effort. Modeling structures are critical but there are many experts to advise on it. But nobody was talking about the dirty work, ETL. In 1999 Sandesh started to take ETL seriously and started to think about strategies that will work for data integration/ETL and data management. The thought process lead him to write a book on ETL. However for many reasons, he realized that he alone cannot finish the ETL book.
In 2005 an ETL book was published by someone else(Kimball group). Not satisfied with the contents, he decided to put his own (real) experience & 200 pages of completed (planned 300 pages) of the book on this website. Thus http://www.etlguru.com/ was born.
We hope the information and services will be useful and valuable to accomplish all your data integration efforts.
