Abstract
A method and system for modular storage of measurement streams using a hierarchy of stream-processing objects. A first application may log measurement data of a plurality of data types to a shared memory location on a first computer, independent of the data type. Both the data and an index to the data may be logged. A second application may trend the data substantially concurrently as the data is logged. Both applications may include a plurality of filter objects, including a hierarchy of stream processing objects, which may operate to log/trend the data. Trending may include: (1) generating a query; (2) determining the location using the index; (3) accessing the data from the shared memory; and (4) displaying the data. The data may be replicated to an archival database, independent of the type of data. The replicated data may be transmitted to a plurality of computers.
