DEDISYS

The major focus of DeDiSys is on optimized dependability by adaptively balancing (trading) availability and constraint consistency. System entities (objects, services) are constraint consistent if constraints (typically predicates stemming from requirements) put on them are satisfied. In data-centric applications the data itself is subject to constraints (data integrity). In service-oriented systems we focus on quality of service constraints... DeDiSys -- Dependable Distributed Systems, An introduction to DeDiSys... DeDiSys provides concepts for optimized dependability for two classes of distributed systems: Tightly coupled, data-centric systems such as distributed object systems and loosely coupled, service-oriented systems such as Web service based Grid systems or peer-to-peer systems.
