The Sensor Integration Platform was developed to access sensor measurements and events as well as to task and control sensor system components in a uniform manner. Its core consists of the so called Tsunami Service Bus (TSB), built on top of a service and messaging backbone. The TSB realizes functional integration compliant to a service-oriented architecture pattern: Functionality is implemented in form of dedicated components communicating via a service infrastructure. These components provide their functionality in form of services via standardized and published interfaces which can be used to access data maintained in and functionality provided by dedicated components. Functional integration replaces the tight coupling at data level by a dependency on loosely coupled services. If the interfaces of the service providing components remain unchanged, components can be maintained and evolved independently on each other and service functionality as a whole can be reused. The TSB provides four services that are realized in conformance to the Sensor Web Enablement (SWE*), a standard specified by the Open Geospatial Consortium (OGC):
