Schema Synchronization Automation
A scheduled synchronization tool designed to reduce schema drift between central and local environments and support a more reliable downtime workflow.
Context
A local pharmacy environment could fall behind the central database structure used by the main system. During a server outage, that mismatch could leave staff working with an older interface and reduce continuity at a time when reliable access mattered most.
Approach
I built a VB .NET console application that compared schema metadata, generated the required update logic, and synchronized selected data between environments. The process was designed to run during lower-risk periods through a scheduler, reducing dependence on repeated manual preparation.
Validation
I considered failure scenarios and post-sync checks as part of the delivery rather than treating a successful script run as sufficient. The goal was a repeatable process that could support operational continuity and be checked after each synchronization.
