Abstract: Interfaces to systems are defined by system files, which inherit attributes of one or more templates in a hierarchy. An access system might provide access and presentation of data to users wherein data is at least in part extracted from a plurality of external applications. The access system comprises storage for a plurality of system templates, storage for a plurality of system definitions, wherein a system definition includes properties and attributes usable to access an external application from a plurality of external applications to obtain data and wherein at least one system definition has at least one of properties or attributes that are inherited from a system template referenced from the plurality of system templates, and storage for a plurality of system connectors, wherein a system connector provides an interface to one of the plurality of external applications. The system connectors might be referenced by a system definition using an alias.
