Best Practices

Understanding owl activities and what the key/date columns mean for each

  • Starting with profile and expanding to rules and then other advanced capabilities.
  • Training with Owl-team Zoom/On-site support
  • Running with sample data
  • Introducing anomalies on sample data and running an owlcheck to see the anomalies.

Using the tool with practical scenarios

  • Having Well Defined Use Cases
    • Determine a single table (dataset) that you would like to scan
    • Have an expectation of what you would expect Owl to find in this dataset
    • Understand which activities would capture the expected findings
  • Target internal datasets with known data issues
  • Historical Comparisons:
    • If pre-cleaned data is available with data findings that have been cleaned via legacy methods such as internal rules, run these datasets and compare the results from Owl to Internal findings.
  • Work with data owners to understand findings or review expected findings

Explorer

  • The date selected with the calendar widget in the Scope (home) tab should align with the calendar widget assigned on the final (Save/Run) tab.
  • If you elect to Unlock the cmd line and override the final parameters, do not re-lock or the changes will be overwritten. In general, only advanced users should override the guided settings.
  • Pushdown and parallel JDBC cannot be used together. If you are using pushdown, do not select the parallel JDBC option

Files

  • File paths should not contain spaces or special characters.
  • Backrun (replay) and advanced features are best suited for JDBC connections. Some features are unavailable if file and storage naming conventions do not consistently contain a date signature.
