| If you are knowledgeable of IBM's DB2 Data
Warehouse Edition based applications and the fundamental concepts of DWE, and
are capable of performing the intermediate and advanced skills required to
design, develop and support DWE applications, you may benefit from this
certification. This certification is applicable to those who specialize in DB2
Data Warehouse Edition and its components for Data Mining, RDA based Data
Modeling, Cube Modeling, SQL Warehousing Tool; and those who design, develop
and administer DWE Warehouse based solutions for Business
Intelligence. |
