Architecture pattern and use case
The use case describes the task; the architecture pattern explains its technical implementation.
What is Architecture pattern and use case?
A use case is a concrete task, such as reviewing documents or screening applications. An architecture pattern describes how the system solves it: for example with a predictive model, document retrieval or an agent with tools. One use case can combine several patterns.
The graphical model in this knowledge base shows a typical setup. Compare it with your actual system and record deviations; the architecture pattern alone does not determine a statutory risk class.
