Common Modeling Techniques

Modeling an Embedded System

To model an embedded system,

Identify the devices and nodes that are unique to the system
Provide visual cues, especially for uncommon devices, by using the UML's extensibility mechanisms to define stereotypes with appropriate icons
For example, we may want to at least distinguish processors (which contain software components) and devices (do not contain software that we build)
Model the relationships among these processors and devices in a deployment diagram
Similarly, specify the relationship between the artifacts in the system's implementation view and the nodes in the system's deployment view

Modeling a Client/Server System

To model a client/server system,

Identify the nodes that represent your system's client and server processors
Highlight those devices that are fundamental to the behavior of the system
For example, we want to model special devices, such as credit card readers, badge readers, and display devices other than monitors because their placement in the system's hardware topology is likely to be architecturally significant
Provide visual cues for these processors an devices via stereotyping
Model the topology of these nodes in a deployment diagram
Similarly, specify the relationship between the components in your system's implementation view and the nodes in your system's deployment view

Modeling a Fully Distributed System

To model a fully distributed system:

Identify the system's devices and processors like in simple client/server systems
If the performance of the system's network or the impact of changes to the network is to be analyzed, model these communication devices to sufficient level of detail
Specify logical groupings of nodes by using packages
Model these devices and processors using deployment diagrams
Where possible, use tools that discover the topology of the system by walking through the system's network
