AbstractThis paper discusses the use of services in the design and development of adaptable business processes, which should let organizations quickly react to changes in regulations and needs. Two types of services are adopted namely Data and Information Technology. A data service is primarily used to hide the complexity of accessing distributed and heterogeneous data sources, while an information technology service is primarily used to hide the complexity of running requests that cross organizational boundaries. The combination of both services takes place under the control of another service, which is denoted by service domain. A service domain orchestrates and manages data and information technology services in response to the events that arise and changes that occur. This happens because service domains are sensible to context. Policies and aspect-oriented programming principles support the exercise of packaging data and information technology services into service domains as well as making service domains adapt to business changes. Keywords: service, service adaptation, context, aspect-oriented programming, policy. |
