DOAF — A development framework for distributed applications

In this paper we present an application development framework that has the goal of supporting the development of distributed applications. The Distributed Operation Application Framework (DOAF) provides standardized interfaces to software developers with the purpose of facilitating the development of distributed applications without caring for topics like: node/replica localization, operation synchronization or conflict management and resolution. The application framework consists of three main components: the Localization component (PathFinder), the Optimizer and the Core. All these components cooperate in order to support the development of distributed applications. The DOAF platform also offers support for optimistic replication of data by maintaining the so called “Distributed Operation” as the main replication strategy.
