• Allows for comparing data elements across applications

  • Finding and reconciling inconsistencies
  • Recognizing commonalties to reduce redundancy

• Improves data integrity

• Provides for greater reuse potential

• Increases interoperability

  • And DISA recommends it
  • See Directive 8320.1-M, Appendix B, Section A.2.c:
    • “… appropriate data administration tools should provide support for … data analysis, cross-referencing and mapping of data in existing systems”
