How Can You Protect Yourself From Unclean Data?

The first step is to stop dirty data from entering your systems in the first place (see error prevention and capture). However this is not always possible, and we have to cope with data from external systems or old data that hasn’t been validated.

So what do we do when unclean data has entered our systems already?

The first step in ridding your business of unclean data is to run an audit on your data. For most businesses, a manual audit of their data would either take too long and/or would not identify all of the issues.

We develop automated tools that will check your data against a set of validation rules to check they are as error free as possible. The validation rules can be as numerous and as complicated as your business needs. Some of the rules our past clients have used include;

  • Checking serial numbers of the correct format
  • Dates are valid and end dates don’t come before start dates
  • Totals add up (e.g. cost + tax really does equal the amount given)
  • Data cross references correctly against other data
  • Checksums calculate correctly
  • Values in one field are dependent on values in other fields
  • Illegal hidden characters are not present
  • Much, much more.

What Can I Do With My Unclean Data?

Once you have identified problems in your data, you have a number of options on how to handle it. These options can be combined to come up with a solution that fits your business.

Automated Fixes

If you can define rules to fix your data, they can be applied as and when issues are found. This can be anything from fixing formatting to applying complex calculations.

Record Deletion

If you want to delete faulty data you can do so. This should probably be the last measure in most cases.

Record Quarantining

An alternative to deleting the faulty data is quarantining it. This usual involves moving the data to a separate spreadsheet or file. Once quarantined the data can be fixed by human operators when possible.

Generate Reports

This will leave the faulty data in situ but record it on a separate report. This will allow human operatives to manually check the data in situ.
