A Unified Approach to Multi-DataBase Query Templates

While trying to get the information he needed out of various SQL, MySQL and Oracle environments, Michael finally got tired of endlessly flicking through reference manuals and having to work so hard just to formulate his queries.

Introducing Microsoft’s Platform for Complex Event Processing

While typical relational database applications are query-driven, event-driven applications have become increasingly important. Event-driven applications are characterized by high event data rates, continuous queries, and millisecond latency requirements that make it impractical to persist the data in a relational database for processing. These requirements are shared by vertical markets such as manufacturing, oil and gas, utilities, financial services, health care, web analytics, and IT and data center monitoring. Event-driven applications use complex event processing (CEP) technology with the goal of identifying meaningful patterns, relationships and data abstractions from among seemingly unrelated events and trigger immediate response actions.
