A container represents an application or a data store; Component diagrams (level 3): decompose containers into interrelated components, and relate the components to other containers or other systems; Code diagrams (level 4): provide additional details about the design of the architectural elements that can be mapped to code.
Since structure diagrams represent the structure, they are used extensively in documenting the software architecture of software systems. For example, the component diagram describes how a software system is split up into components and shows the dependencies among these components.
A deployment diagram [1] "specifies constructs that can be used to define the execution architecture of systems and the assignment of software artifacts to system elements." [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 ...
An example of two components in UML: Checkout processes a customer's order, which requires the other one to bill the credit card. For large-scale systems developed by large teams, a disciplined culture and process is required to achieve the benefits of CBSE. [4] Third-party components are often utilized in large systems.
Software architecture is the set of structures needed to reason about a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations.
The object collaboration diagram shows the run-time interactions: In this example, the Client object sends a request to the top-level Composite object (of type Component) in the tree structure. The request is forwarded to (performed on) all child Component objects (Leaf and Composite objects) downwards the tree structure.
"An object diagram is a graph of instances, including objects and data values. A static object diagram is an instance of a class diagram; it shows a snapshot of the detailed state of a system at a point in time. The use of object diagrams is fairly limited, namely to show examples of data structure."
The component diagram extends the information given in a component notation element. One way of illustrating a component's provided and required interfaces is through a rectangular compartment attached to the component element. [3] Another accepted way of presenting the interfaces is the ball-and-socket graphic convention.
