Open Studio for Data Quality

You can add one or more regular expressions to one or more of the analyzed columns.

Before you begin

An analysis of a delimited file is open in the analysis editor in the Profiling perspective.

Procedure

  1. Define the regular expression you want to add to the analyzed column.
    In this example, the regular expression checks for all words that start with uppercase.
  2. Add the regular expression to the analyzed column in the open analysis editor, the first_name column in this example.
  3. Save the analysis and press F6 to execute it.
    If the format of the file you are using has problems, you will have an error message to indicate which row causes the problem.
    The detailed analysis results view shows the generated graphics for the analyzed columns accompanied with tables that detail the statistic results.
    Below are the tables that accompany the statistics graphics in the Analysis Results view for the analyzed first_name column in the procedure outlined in Defining the columns to be analyzed in a file.
