7. Systems 317
architectures manifests on all layers except the integration layer. Task flows in
the integrated work place are supported by workflows as part of information services.
Transaction systems execute processes in the layer of information
sources.

FIGURE B-57. Integrated, layered architecture for KMS 514
Becker et al. (2002, 24) present an architecture that views KMS from the perspective
of meta-data (see Figure B-58). The starting point for this architecture
is the observation that in most organizations there are already a number of application
systems installed that provide a substantial portion of the functions that
are required for KM. Becker et al. conclude that the KMS additions are basically
restricted to the integration of these application systems with the help of a
defined set of meta-data and a knowledge portal. Examples for application systems
that provide KM functionality are content management systems, data
warehouses, enterprise resource planning systems and workflow management
systems. Each of these systems handles its own meta-data. Consequently, a
KMS needs to align the meta-data of these systems. A knowledge management
portal accesses the contents of these application systems on the basis of a separate
data base with integrated meta-data drawn from these systems.
