Compare | Data IBM, Oracle, Sybase, CA, NCR, Informix, Microsoft, SAS and other powerful companies have launched their own data warehousing solutions (through acquisitions or research and development). Professional software companies such as Bo and Brio also have a place in the front-end online analytical processing tools market. The following is an analysis and

New data needs to be updated to these tables on a daily basis.
The procedures for updating these tables (programs) are developed at the very beginning, and each day only needs to pass some parameters, such as dates, to run the programs.
