1. A method of supporting a family of logics defining windows of continuous data streams in a data stream management system, said method comprising:

  • receiving a common software code designed to execute using a set of values as parameters, wherein execution of said common software code with a corresponding set of values results in a corresponding one of said family of logics;

    receiving a query to be executed on a continuous data stream, wherein said first query specifies a first set of parametric values corresponding to a desired logic contained in said family of logics;

    determining a set of data values to be included in a first window by executing said software code using said first set of parametric values as said set of values, wherein said set of data values is contained in a plurality of data values received in said continuous data stream; and

    generating an output of said query based on said set of data values included in said first window.
