Unit 9/Chapter 10 - Technology Layer Flashcards
The node, the technology interface, system software, devices, communication networks
Active Structure
Subjects (technology) that perform behavior such as technology services (external behavior), technology function/processes (internal behavior)
Behavior Aspect
Manipulated by behavior elements
Passive Structure Elements
Used to model structural entities; main active structure element
Node
The logical place where technology services offered by a node can be accessed by other nodes or by application components from the Application Layer
Technology Interface
Models the relation between two or more nodes, through which these nodes can exchange information
Path
Physical realization of a path is modeled as:
Communication network
Technology Layer Active Structure Elements:
Node, Device, System Software, Technology Collaboration, Technology Interface, Path, Communication Network
A computation or physical resource that hosts, manipulates, or interacts with other computational or physical resources
Node
Node
A physical IT resource upon which system software and artifacts may be stored or deployed for execution
Device
Device
Typically used to model hardware systems such as mainframes, PCs, or routers
Device
Provides or contributes to an environment for storing, executing, and using software or data deployed within it
System Software
System Software
An aggregate of two or more technology internal active structure elements that work together to perform collective technology behavior
Technology Collaboration
Technology Collaboration
A point of access where technology services offered by a node can be accessed
Technology Interface
Technology Interface
A link between two or more nodes through which these nodes can exchange data, energy, or material
Path
Path
A set of structures that connects nodes for transmission, routing, and reception of data; represents physical communication infrastructure
Communication Network
Communication Network
Examples include: parameters, protocols, pre & post conditions, data formats
Technology Interface
Technology Layer Internal Behavior Elements:
Functions, processes, interactions
A collection of technology behavior that can be performed by a node.
Technology Function
Technology Function
A sequence of technology behaviors that achieves a specific result.
Technology Process
Technology Process
A unit of collective technology behavior performed by (a collaboration of) two or more nodes.
Technology Interaction
Technology Interaction
A technology state change.
Technology Event
Technology Event
An explicitly defined exposed technology behavior.
Technology Service
Technology Service
Technology Layer Passive Structure Elements
Artifact
A piece of data that is used or produced in a software development process, or by deployment and operation of a system.
Artifact
Artifact
Used to model software products such as source files, executables, scripts, database tables, messages, documents, specifications, and model files
Artifact
Can be used to represent a physical data component that realizes a data object
Artifact
Execution component or a data file
Artifact
