Ambica was brought in to improve the performance of the SMS databases and applications and to work on enhancements. SMS was a client/server system used to store information about cable TV and telephone customers and was divided into three applications: Sales Order Processing (SOP), the Despatch Management System (Despatch) and VT (Batch and Standing Data Maintenance). The front-end had been written using:

  • CA-OPENROAD 3.5/02
  • MS Windows NT 3.51
  • CA-INGRES ABF/4GL
  • SQL
  • VAX/VMS 6.2.

The back-end was on four CA-INGRES 6.4 databases on two Digital VAX machines running VAX/VMS 6.2.
