Impact Analysis for Shared Databases: The 9-App Problem

One database, many masters

Legacy estates often grow into a shared-database architecture: multiple applications, built over years by different teams, all reading and writing the same tables. It's efficient until you need to change something — then it's terrifying.

The cross-app blind spot

Each application team knows their own code. Nobody has a view across all nine. So a change that's safe in one app silently breaks another, and the failure surfaces in production, in a system the author never opened.

A portfolio graph

CodeIQ Pro builds a knowledge graph per application and a portfolio view across them. Ask which applications write a given table and you get the real answer spanning the whole estate — not just the app in front of you.

Change with the whole picture

Before altering a shared table, you can see every application, function and screen that depends on it, everywhere. The 9-app problem stops being a source of production surprises and becomes a coordinated, visible change — planned across teams instead of discovered by users.
