UML sequence diagrams model the flow of logic within your system in a visual manner, enabling you both to document and validate your logic, and are commonly used for both analysis and design purposes.
Messages are indicated on UML sequence diagrams as labeled arrows, when the source and target of a message is an object or class the label is the signature of the method invoked in response to the message.
I used a UML note in Figure 4; notes are basically free-form text that can be placed on any UML diagram, to provide a header for the diagram,indicating its title and identifier (as you may have noticed, I give unique identifiers to all artifacts that I intend to keep).
UML is a general-purpose modeling language that includes a standardized graphical notation that may be used to create an abstract model of a system, sometimes referred to as the UML model.
Ed Eykholt chaired the overall UML proposal effort, and Cris Kobryn chaired the UML Semantics Task Force, which was tasked with defining the semantics for the UML notation.
Since UML is specified by a combination of itself (abstract syntax), OCL (well-formedness rules) and English (detailed semantic), it lacks the rigor of a language precisely defined using formal language techniques.
Unified Modeling Language (UML) is one tool that allow developers and architects to ease the process and create a big picture before committing to a particular technology.
UML allows architects, developers, management, testers, designers, and users to come together and create a software model in an abstract fashion.
UML models are diagrams of three primary types: structural, behavioral, and interaction.
