Abstract: Design and deployment of an interface for a data processing application is facilitated by a tool, preferably implemented in software, which parses a description of data to form a hierarchy of groups of selector, terminal and intermediate attributes, including generation of attributes through specification of analyses of data, to develop an interface building program which, when executed, builds an interface for the data processing application. The attributes of the hierarchy are configured into layers, analyses are selected and/or specified, interface display pages are configured and global controls are specified using the tool. Markers having freely definable visual attributes and properties corresponding to analysis results such as return codes provide a condensed display which also facilitates access to data nested beneath each marker.
