Lynx Profiler our Data Quality software is a commercial Data Quality package and our customers include the National Policing Improvement Agency who licensed the software for all 43 Police Forces to improve the quality of police operational data.

We have experienced data quality consultants to undertake your quality improvement program along with administrative staff who can perform manual data cleansing should it be required.

Using our standard methodology Datalynx can undertake a complete data quality assessment for you. From defining the data quality measures that are important to you, through to analysing your data and, if required, correcting it. The data quality software can then be configured to perform regular data quality assessments.

We have a standard two phase approach which can be adapted to your requirements;

Data Quality Investigation

The goal of the phase is to identify your specific data quality rules, assess the data, quantify the data quality challenge and agree the actions to improve the data quality.

This would be achieved by undertaking the following tasks –

  • Initial data quality analysis using our standard data quality measures
  • Data quality rules discovery
  • Full data quality assessment using the expanded data quality rules
  • Develop and agree a “Data quality management specification (DQMs) which defines how each issue should be addressed


  • Initial and full Data Quality reports
  • Data Quality management specification
  • Proposal and estimate for the Data Quality Improvement Phase

Data Quality Improvement

The goal of this phase is to put in place the measures to improve your data quality

We would employ different data quality improvement techniques to correct the data quality issues dependant on the volume and nature of data quality issues discovered in your data:

  • Manual
  • Scripted or programmatic correction
  • Report for addressing by you.
  • Augment or correction with external sources for example
    – Address cleansing
    – Removal of gone aways, opt outs and the deceased

Where the number of errors is low or difficult to correct in an automated manner DataLynx can supply the necessary resources to manually correct the data wherever appropriate.
