![]() Dependency: When changes in one class cause changes in another class, they are dependent.For example: a FailedStudentsList will know about the Student class, but the Student class is not aware of the FailedStudentsList class. One way: Only one class knows about the other – use an open arrow head.Bi-directional: Both classes know about the association – draw a solid line between the classes, with no arrows.When a link exists between classes you can indicate it in a number of ways. It’s perfectly normal to need to correct or modify your earlier diagrams – think of it as parallel diagramming! Class diagrams are not just used for programmingįor example, business analysts can model the company structure of assets and processes associated with them. But as you work on later diagrams, especially those in the other category, you’ll almost certainly find you have missed things. Of course, you can develop the different UML diagrams in the order that you prefer. Probably the most well known structural diagram are class diagrams, which specify the data structures and their relationships within your program. I’d like to jump to the other category of UML diagrams – structural diagrams. In previous posts, you have seen two examples of behavioural diagrams (use case models and activity diagrams). They help you clarify requirements and limitations, speed up the implementation, provide a guide for thorough testing, and prevent bugs from sneaking in throughout the entire software development process. ![]() There are a wide range of diagrams to help you specify your data and processes before you start programming. ![]() The Unified Modeling Language or UML notation is probably the most well known and regularly used visual representation of programs that you’ll find in software development. ![]()
