The Little Pattern That Could - Leveraging the Power of Repositories

(This is a hands-on lab with limited capacity)

The Repository pattern is one of the oldest and most well-known patterns in software architecture. It is simple, elegant, and easy to grasp - or is it? There are actually many versions of this pattern, some in books, some implemented in frameworks, which all look similar, but differ greatly, both in usage and outcome.

This workshop will (re-)introduce the Repository pattern as intended in Domain Driven Design: An elegant way of keeping persistence and domain logic decoupled, improving testability, and creating options for evolutionary development.

We will use ensemble programming to explore different applications of the pattern together, discuss pros and cons, and refactor an existing code base to see the resulting effects.

Prerequisites

All skill levels are welcome - we will work as a group and help each other out. You can join with your own laptop and setup you feel comfortable with, or use the one provided in the session, when it‘s your turn to drive. A git repository for the source code and installation instructions will be shared with you before the event.
