Computer Integrated Manufacturing involves collaboration and exchange of information among several groups of engineers. A Concurrent Engineering environment uses CIM technologies to handle shared information. Such applications are both data-intensive and computation-intensive. A natural architecture to support the management and sharing of information for this application is a network (federation) of heterogeneous and autonomous agents that are some loosely and some tightly-coupled. This paper presents a preliminary study in the design of a distributed CIM database for an aerospace industry in Brazil. In this effort, first some information modelling requirements are distinguished. Then, a federated information management system PEER, that handles the requirements, is described.
