Definition
Software that connects two or more applications, translating data formats and managing communication between systems.
In Depth
Middleware sits between systems, handling data transformation, protocol translation, message queuing, and error handling. It decouples systems so they can evolve independently while maintaining integration.
Example Usage
Building a FastAPI middleware layer that normalizes data between Shopify orders and NetSuite sales orders.
Business Context
Middleware simplifies complex integrations by centralizing transformation logic, making it easier to add or replace systems without rewriting every integration.
