1. A method for use with a network management unit to be used in a network management system including at least one enhanced network element to obtain query results the method comprising the steps of:

  • obtaining an inputted query that is a declarative language query;

    determining a set of enhanced network elements required to answer said declarative language query;

    computing a query execution plan for each determined enhanced network element;

    employing a query optimizer to compute each of said query execution plans;

    transmitting an associated computed query execution plan to each determined enhanced network element;

    obtaining results of said query execution plans from said at least one determined enhanced network elements;

    combining said obtained results to generate a query result; and

    displaying said query result;

    in said at least one enhanced network element obtaining a query execution plan from said network management unit, a query that is the basis for said query execution plan being a declarative query language query;

    translating said query execution plan into a sequence of network management calls that are simple network management protocol (SNMP) calls;

    employing a SNMP wrapper to translate said declarative query language query to said SNMP calls;

    executing said sequence of network management calls to obtain a corresponding sequence of query results and correlating said sequence of query results; and

    supplying said correlated query results as an output from said at least one enhanced network element to said network unit.
