The ReportService supports methods to create, process and find report instances. A Report Entity is identified by its name represented by the attribute 'name' So a ReportService Implementation should ensure that name is a unique key for the report entity. Also each report entity holds a EQL Query in the attribute "txtquery". this eql statement will be processed by the processQuery method and should return a collection of entities defined by the query.
