Process Managers Made Simple

Process Managers / Sagas / Orchestrations are one of the eternally discussed topics in Event Sourcing . We will cover how by properly defining the problem and goals we are trying to address ,the question "What is a process manager, and do I need one?" becomes trivial both to answer, and to use.


Data Modeling in an Event Centric World

When moving to an Event Centric data model it often feels like all of the data modeling tools and skills we have built over the years in more traditional systems are lost. In truth it is the exact opposite. Not only can we bring all of our hard-won knowledge on Data Modeling with us, Event Centric systems give us new and exciting Data Modeling tools that enhance our traditional toolboxes. With practical examples we walk a straight line from traditional relation data models into best practice Event Models. In addition, we can apply well known rules from traditional modeling to know why these new models are ideal for various usages.

Data on the Inside: Understanding large scale system design in Event Driven Systems

Inspired by Pat Helland's excellent paper "Data on the Outside vs. Data on the Inside" we explore one of the most insidious anti-patterns seen in building integrated Event Driven Systems. The failure to correctly separate private and public data in event sourced integrations lead to endless trouble. Correctly segmenting and modeling public and private data is the most important element in building integrated Event Driven systems.
