Writing Query Templates in LINQ
Once data has been delivered into the StreamInsight server, computation may be continuously performed over the data. In other words, as events are inserted into the server, these events are processed by standing queries, which emit the processed output events. These standing queries are written in the language framework LINQ. LINQ is a mechanism for expressing declarative queries over data sets that is fully integrated into a host language such as C#. In the current release, StreamInsight only supports C# as a host language.This framework has been adapted for the StreamInsight platform, resulting in a tight integration of the StreamInsight server with C#. The topics in this section demonstrate a number of computational operations over events supported by this platform and demonstrate how these operations are specified with StreamInsight LINQ queries.
