Problem Statement

Our Client wanted to run a research project to build a multi-backend platform for their educational applications starting with their existing Oracle-based applications as they started cloud-based, online offerings. This meant two important constraints of their requirements.

  • Compatible database schemas and packages between different databases like Oracle and PostgreSQL, needed from current Oracle schemas and packages with:
  1. Minimal application changes
  2. Minimal data migrations from legacy / Oracle
  • Minimal manual interventions for maintaining bidirectional compatibility while changes may originate from any of the supported databases
