Use Cases

  • Dictionary lookup and field explanation
  • SQL filtering and grouping
  • Analytical reporting and reusable query building

Common Usage

  • audit trail and record stewardship review
  • identifying recent data maintenance activity
  • filtering transactions last edited by a specific user or domain

Common Mistakes

  • confusing the editor identifier with the contractor or awarding official
  • using it as a procurement performance or award characteristic

Query Guidance

Use exact-match or pattern-based filters on the string value, for example WHERE lastModifiedBy = 'LYDIA.RICHARDS.HR0011@DARPA.MIL' or WHERE lastModifiedBy LIKE '%@DARPA.MIL'. For analysis, group carefully because this is high-cardinality text and may reflect individual accounts rather than stable organizational units.
