Abstract: A revenue assurance system includes one or more servers coupled with one or more databases and providing a number of displayed fields/selectors on computer interfaces. A business area selection field allows selection of a business area. A first data source field receives selection of a first data source. A first input field receives selection of one or more first data associated with the first data source. An operator field receives selection of a mathematical symbol. A second input field receives a constant or selection of one or more second data. A database query is generated and executed to retrieve data from the database(s), the query defined at least in part by the first data source field, the first input field, the operator field, and the second input field. A graph representatively illustrates the data retrieved by the database query and displays business revenue-related information relevant to the selected business area.
