In the previous articles we have described how Hierarchical State Machines (HFSMs) can be used to define the whole application logic and advantages of using Services, Extension Extension Points to build user interfaces. This blog post continues this series and describes how these architectural patterns are used together. Demo : A

This article is about Deterministic Hierarchical Finite State Machines (DHFSM) and how we use them to build applications - especially web applications. Finite State Machines - FSMs - is a very old and well known formalism used to describe the behavior of dynamic systems as a set of states and

Services allow to dynamically (at run time) add functionalities in existing applications without changing the application itself. The Georito platform is based on a simple implementation of this Service Provider / Consumer pattern. The main idea of this pattern is that one part of the system can dynamically register, update and

In this blog post we want to put at your disposal our open source library @agen managing and transforming data streams.
