In this blog post, I will explain how I implemented a graph algorithm to solve the database migration problem in an application pluggable module system.

Prerequisites:

• Working knowledge of Python
• Working knowledge of Graph Theory. Familiar with the terms: Edge, vertex, path, sink, source, digraph, path graph, etc.

Gavika Web Framework has a pluggable module system. The modules can be developed independently. They can be installed, upgraded and removed from the main application. Gavika Web Framework is written using Python, Flask, SQLAlchemy and a bunch of other related technologies and libraries.
