The UML

• UML stands for Unified Modelling Language
• The UML is primarily a graphical notation used for modelling systems using object oriented concepts
• The UML is emerging as an industry standard for object oriented modelling
• In additional to this the UML is recognized as the standard language for use with OO Analysis & Design by the Object Management Group (OMG)
• The UML consists of a number of graphical elements that are combined to form diagram
• The UML language specifies rules for combining these graphical elements
• The purpose of producing these diagrams is to represent multiple views of the system
• This set of views is collectively referred to as a model of the system
• UML enables the software developer to understand certain concepts of the system more clearly.
• When understanding programming languages, the results are precise but too much detail is needed to gain the results
• When using UML the developer can gain a certain amount of precision and avoid getting lost in detail
• That does not mean that the detail is avoided, rather that the UML can highlight the important detail
