<h1>ETL – Best tool to build the data warehouse</h1><strong> Author: <a href='http://www.articleseen.com/profile_Denish.aspx'>Denish</a></strong><br /><p>ETL tools nowadays considered the most efficient software product to load data into a data warehouse. Initially data warehouses were not observed as being proficient of handling the wide processing needed to achieve the typical data transformations involved in the warehouse load method. Instead, third-party tools were leveraged to organize data transformation between source systems and the data warehouse. With the improvement in both hardware and data warehouse software technology, warehouse designers can now consider extract, load and transform (ELT) a feasible choice. ETL Tools also offers consistent environment for dissimilar data. Designers should evaluate the amount of the information to be transformed by data warehouse ETL. Occasionally it is numerous TB (terabytes) per hour, sometimes less and data is transformed onto predefined controlled structure which is called enterprise data warehouse. ETL tools capture transformation of data from the ETL process in a meta data repository. This centralized repository can enable communication between the associates of the warehouse development team: the end-user, the subject matter professional, the data warehouse designer, the programmers and others. The data in the repository is then accessible for subsequent warehouse programmers adding a subject or changing a current area who must recognize existing transform logic before developing new logic. The centralized repository in ETL permits data modeling problems to be fixed with input from team members and then offers consolidated access to the resulting model. ETL can offer a technical foundation for this effort if they comprise a complete repository tool. This centralized repository plus various time-saving ETL tools for the extraction, transformation and loading of data to develop an important value-proposition for data warehouse programmers. ELT software also uses typical transfer mechanisms such as FTP to transfer the data right to the data warehouse system. The transformation business rules are then applied and the data warehouse tables are loaded in the system.
