- Objective : Handle key data management services close to data, the database. Managing data is Oracle’s core competency.
- Model structure is expressed as an Event Processing Network (EPN) An EPN describes collaborating producers and consumers of events. The EPN is a directed graph made up of: Adapters – translate external events/data into events that are processed by rules Streams – connect sources and sinks to configure the flow control Processors – set of rules that are applied to streams that the processor listens to Listeners - event sinks implemented as POJOs that implement the business logic necessary to handle raised events A WLEvS application is defined via a Spring configuration file WLEvS custom tags declare instances and relationships of EPN elements (e.g. <wlevs:adapter>) Events Implemented as JavaBean or Map Registered with a runtime service Adapters, Processors, and Events Are published via OSGI services and can be shared across applications
