The Lost Art of Data Profiling

Bob Conway, Information Engineering Associates

Data profiling is the technique of inferring the true semantic meaning of data by carefully scrutinizing the structure and content of existing databases.  The title refers to data profiling as an art because it is much more than mechanically capturing distinct values and min/max values of data elements.  Data profiling is the heuristic interpretation of those statistics to discover the underlying business rules.  Data profiling is true reverse engineering.

This bottom- up method of data modeling is a valuable complement and validation of top down modeling methods such as user interviews and group consensus (JAD) sessions.  Data profiling is also the most reliable way to identify data quality issues and design ETL procedures to mitigate them.
