MIDA: An open systems architecture for model-oriented integration of data and algorithms

摘要

MIDA defines an architecture for building distributed Decision Support Systems by integrating high-level modeling approaches and implementation techniques for platform independent distributed client/server applications. One of the chief design goals is hiding of all infrastructural and system specific implementation details to users. MIDA covers solutions for model-oriented representation, administration, and (remote) access to both data and methods in distributed heterogeneous computer and networking environments. AMBAS-SOOM is an implemented variant of the MIDA architecture which has been developed at FAW. AMBAS-SOOM has two main components: the distributed operating platform AMBAS and the modeling environment SOOM, which implements concepts of Structured Modeling (SM) and Object Orientation. Models are developed using the graphical expert interface of SOOM and include formal descriptions of data types, of methods (functions, solvers) and relationships between data and methods. These models are translated automatically into executables for AMBAS. AMBAS contains an Object Request Broker mechanism to assign requests for data or methods from applications to services available within the network and, therefore, enables reuse of distributed data and methods to build up new models.
