2.0 NetWeaver Object Model and Enterprises
Architecture
This section focuses on overview of the object
model of NetWeaver. This basic knowledge facilitates the
organizations in constructing an apprehensible knowledge base. The
various components that are present in NetWeaver Object Model are
Data Links, Dependency Networks, Nodes and in some cases, evaluation
groups. Each of these components and their function in the NetWeaver
Object Model is described below:
- Data Links: These objects of the NetWeaver function to request
data about the real-world objects. They can also be defined as the
objects that have one-to-one relation with the real-life objects
and can be logically and mathematically manipulated. Thus, making
the knowledge representation in NetWeaver simple as well as
insightful. Moreover, these objects are reusable and can be
referred as and when required.
- Dependency Networks: The dependency networks in NetWeaver play
the central role in formulating the representation of the problem.
These dependency networks are used to interconnect different
objects in the object model. Therefore, they are considered to be
the most important factor in the object model of NetWeaver. Using
the "New Network" that is present in the network window can create
a new dependency network. Also, new dependency networks can be
added in the object model in the later stages without creating any
interference with the already existing knowledge base.
- Nodes: Nodes function to form the relation between data links
and dependency networks. Nodes are classified into logical nodes
and functional nodes. The logical nodes define the dependencies of
the network on its antecedents and the functional nodes are used
to construct the mathematical relation in the data links.
- Evaluation Group: An evaluation group is a user-defined
collection of networks. An evaluation group specifies a collection
of networks that are conceptually relevant to one another and that
the knowledge base designer wants to see evaluated as a set.
