Object-oriented database management systems (OODBMS) are expected to serve advanced application domains such as engineering design, office information systems, imaging systems, and multimedia. This book, based on a NATO Advanced Research Workshop, covers all aspects of object-oriented database systems from design principles to implementation of prototypes. Topics covered include model concepts, query optimization, query languages, functional programming formalism, storage systems, transaction models, interoperability, distributed computing, rule languages, open architectures, hypermedia systems, and many others. Designers and developers will benefit from the comprehensive presentation of the various modules of such systems, while practitioners will find examples of implemented prototypes.

Workflow management systems enjoy increasing popularity due to their ability to coordinate and streamline complex organizational processes within organizations of all sizes. Control of these processes allows an organization to reengineer and improve or adapt them. Interest in workflow management systems was demonstrated in the early 1990s by an increased number of commercial products in an estimated USD2 billion market. This book addresses recent advances in workflow management systems. Based on a NATO workshop held in 1997, it is an integrated collection of papers by leading international researchers. Topics emphasized include interoperability, Internet technologies to improve system capabilities, scalable and dynamic cooperation technologies, and workflow system prototypes.

Object-oriented database management systems (OODBMSs) have generated significant excitement in the database community in the last decade. This interest stems from a real need for data management support for what are called "advanced application areas" that are not well-served by relational technology. The case for object-oriented technology has been made on three fronts. First is the data modeling requirements of the new applications. Some of the more important shortcomings of the relational systems in meeting the requirements of these applications include: 1. Relational systems deal with a single object type: a relation. A relation is used to model different real-world objects, but the semantics of this association is not part of the database. Furthermore, the attributes of a relation may come only from simple and fixed data type domains (numeric, character, and, sometimes, date types). Advanced applications require explicit storage and manipulation of more abstract types (e.g., images, design documents) and the ability for the users to define their own application-specific types. Therefore, a rich type system supporting user defined abstract types is required. 2. The relational model structures data in a relatively simple and flat manner. Non traditional applications require more complex object structures with nested objects (e.g., a vehicle object containing an engine object).

Workflow management systems (WFMS) are enjoying increasing popular ity due to their ability to coordinate and streamline complex organizational processes within organizations of all sizes. Organizational processes are de scriptions of an organization's activities engineered to fulfill its mission such as completing a business contract or satisfying a specific customer request. Gaining control of these processes allows an organization to reengineer and improve each process or adapt them to changing requirements. The goal of WFMSs is to manage these organizational processes and coordinate their execution. was demonstrated in the first half The high degree of interest in WFMSs of the 1990s by a significant increase in the number of commercial products (once estimated to about 250) and the estimated market size (in combined $2 billion in 1996. Ensuing maturity product sales and services) of about is demonstrated by consolidations during the last year. Ranging from mere e-mail based calendar tools and flow charting tools to very sophisticated inte grated development environments for distributed enterprise-wide applications and systems to support programming in the large, these products are finding an eager market and opening up important research and development op portunities. In spite of their early success in the market place, however, the current generation of systems can benefit from further research and develop ment, especially for increasingly complex and mission-critical applications.
