WSO2 DAS stores the received events and processed data in its underlying data storage system, where that data can be retrieved using the standards APIs that have been defined. Analytics REST API allows external parties to query this data. When this API is used independently of the backend data store, it can be used to lookup/search for data that is stored in the system. e.g., this can be used by any server side application, mobile application etc. anywhere the HTTP based service can be accessed.
