Example A7 Business Re-Engineering

• IWIMS is comprised of 212 individual databases
• ACES-Personnel Readiness is comprised of 194
  individual databases
• ACES-Real Property is comprised of 194
  individual databases and utilizes the Command RP
  database to consolidate data for annual reporting
  requirements
• ACES-FD is comprised of 194 individual
  databases hosted at each installation
• ACES-HM and FMO are each comprised of 194
  individual databases
