Abstract: A method for integrated database user privilege management can be implemented. The method presents a computer interface for managing access privileges of one or more users to a database comprising independent data and dependent data, and retrieves one or more role objects, record filter objects, and attribute filter objects assigned to a user. A role object defines access privileges to selected values of the independent data and dependent data. A record filter object can modify the access privileges defined in the one or more role objects. An attribute filter object defines access privileges to selected attributes of the independent data. The method can calculate, and present on the computer interface, a list of attributes of the independent data and a list of dependent data that the user has access privileges based on the one or more role objects, record filter objects, and attribute filter objects assigned to the user.

Abstract: A convertible ladder and scaffold assembly includes a plurality of uprights and a plurality of beams each extending from one of the uprights. A plurality of hinges each hingedly connect one of the uprights to one of the beams about a rotational axis (AR) to provide an assembly having ladder, scaffold, push-cart, and storage configurations. Each of the hinges defines catches and present a stop releasably engaging catches for preventing rotation about the rotational axis (AR). At least one lever bar releasably engages a plurality of the stops for simultaneously releasing a plurality of the stops from engaging catches. Each of the lever bars have a plurality of lever sections for providing leverage to disengage the stops from the catches. Each of the lever bars has a grip section interconnecting the lever sections for simultaneously releasing a plurality of the stops from engaging the catches.
