Flexible business-oriented service interfaces in information systems

摘要

Information systems supporting flexible business in small-to-medium enterprises must be easily modifiable under the supervision of their users. The users (business people) must take active part in agile system development and maintenance. The systems must be able to integrate large legacy systems and to communicate with the systems of independent business partners. Business processes need not be executed by a single ERR We discuss a variant of SOA able to meet these requirements. The discussed SOA uses communication protocols based on problem-oriented languages. We propose a concept of organizational (architectural) services generalizing the concept of connectors and routers. The power and usefulness of the proposal is demonstrated on the examples of service composition, business-oriented interfaces, agile business processes, portals, and gateways. The proposal is based on experience from practical SOA projects.
