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.
