A Pipeline-Oriented Data Management System: Design and Implementation with an OODBMS

A project is described, aiming at the design and implementation of DMC, a data management system built on top of a commercial Object-Oriented Database Management System (OODBMS) and particularly suited to handle data processing pipelining tasks. Although the design of the system is quite general, specific reference is made to its incarnation developed for the ESA Planck mission. Beating heart of the Planck IDIS information system, DMC is the tool chosen by the two Data Processing Centres (DPCs) as a common language for the data handling applications being developed. Particular reference is made to the design of the model, to the data structures and to the portability to other experiments of the main features of the service suite provided.
