Course Description
Contains: PDF course guide, as well as a lab environment where students can work through demonstrations and exercises at their own pace.
This IBM InfoSphere Advanced QualityStage V11.5 course will step you through the QualityStage data cleansing process. You will transform an unstructured data source into a format suitable for loading into an existing data target. You will cleanse the source data by building a customer rule set that you create and use that rule set to standardize the data. You will next build a reference match to relate the cleansed source data to the existing target data.
