Description: Consider the Healthcare Sales Management system again, this time you are required to draw a deployment diagram for the scenario given below:


Architecture of health care management system consists of two tiers of servers; application server and database server. We have one application server and two database servers. Both database servers are identical; first acts as a main server, while the second acts as a redundant backup in case the first one fails. Clients can access database server through application server.

For above system, we also have the option of using a proprietary client that accesses the databases directly.



  1. Given the above scenario, you are now required to draw deployment (physical) view based on Krutchen’s 4+1 architectural model for the above system depicting normal client access scenario as well as proprietary client access scenario.
  2. You are also required to explain your deployment diagram that how data will flow from client to server and then from server to client (request initiation to reply from server). Explanation of deployment diagram should be done in not more than 4 to 5 lines.

Q: What is a Deployment Diagram?
Ans: A deployment diagram in the Unified Modeling Language models the physical deployment of artifacts on nodes.[1] To describe a web site, for example, a deployment diagram would show what hardware components ("nodes") exist (e.g., a web server, an application server, and a database server), what software components ("artifacts") run on each node (e.g., web application, database), and how the different pieces are connected (e.g. JDBC, REST, RMI).

The nodes appear as boxes, and the artifacts allocated to each node appear as rectangles within the boxes. Nodes may have subnodes, which appear as nested boxes. A single node in a deployment diagram may conceptually represent multiple physical nodes, such as a cluster of database servers.

There are two types of Nodes .
Device Node
Execution Environment Node
