Chapter 20. Identity Mapping and De-Duplicating

Exam objectives in this chapter:

Extract and Transform Data
- Design data flow.
- Implement data flow.
Build Data Quality Solutions
- Create a data quality project to clean data.

Two of the most challenging problems with maintaining master data are identity mapping and de-duplication.

In an enterprise, you frequently have more than one source of master data. Sometimes you have to import master data from outer sources. Different sources can include older applications; relational databases used by OLTP applications; analytical databases; semi-structured data, such as XML data from a web service; and even non-structured data in Microsoft Excel worksheets and Microsoft Word documents. Typically, you do not have unique ...
