You can examine the data available in single tables of a database and collect information and statistics about this data.

The sequence of profiling data in one or multiple tables may involve the following steps:

  1. Defining one or more tables on which to carry out data profiling processes that will define the content, structure and quality of the data included in the table(s).

  2. Creating SQL business rules based on WHERE clauses and add them as indicators to table analyses.

  3. Creating column functional dependencies analyses to detect anomalies in the column dependencies of the defined table(s) through defining columns as either "determinant" or "dependent".
