Could you please provide me with some resources/direction for data profiling tools that will give me a better understanding of the quality of my data?


Sid Adelman's Answer: While data profiling tools can evaluate certain types of data quality including missing data, conformance to valid values and business rules, and incorrect data types, it's still hard work to define the rules to the profiling tool. The high-end tools also provide profiling but they are costly. Most of the profiling tools will give you the capabilities you need so look for ease of use, support of your DBMS and platform, vendor support and cost.
