text_B: A deployment diagram in the Unified Modeling Language models the physical deployment of artifacts on nodes .. Unified Modeling Language. Unified Modeling Language. artifacts. Artifact ( UML ). nodes. Node ( UML ). To describe a web site , for example , a deployment diagram would show what hardware components -LRB- `` nodes '' -RRB- exist -LRB- e.g. , a web server , an application server , and a database server -RRB- , what software components -LRB- `` artifacts '' -RRB- run on each node -LRB- e.g. , web application , database -RRB- , and how the different pieces are connected -LRB- e.g. JDBC , REST , RMI -RRB- .. artifacts. Artifact ( UML ). nodes. Node ( UML ). The nodes appear as boxes , and the artifacts allocated to each node appear as rectangles within the boxes .. artifacts. Artifact ( UML ). nodes. Node ( UML ). 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 .. nodes. Node ( UML ). There are two types of Nodes  :. Device Node. Execution Environment Node. Device nodes are physical computing resources with processing memory and services to execute software , such as typical computers or mobile phones .. nodes. Node ( UML ). An execution environment node -LRB- EEN -RRB- is a software computing resource that runs within an outer node and which itself provides a service to host and execute other executable software elements .
