repetition, there is a list in a, which holds the B object's n references , that's it.Well, to here, already put the above diagram of the relationship is finished, I hope you can have some gains, I also spent a lot of time ah (drawing, generate code, write to the blog, alas, a sweat). But it's worth it if you can get a thorough understanding of these relationships in UML class diagrams. :)+++++++++++++++++

extension cases in extend provide direct service to participants, while the use cases included in the include provide indirect services to participants.For extend, the extension use case does not contain the content of the underlying use case, nor does the underlying use case contain the content of the extension use case.For inheritance, a child use case contains all the contents of the underlying use case and its relationship to other use cases or actors;A use case

OverviewTime series diagrams (Sequence Diagram) describe the chronological order in which messages are routed between objects, which are used to denote the order of behavior in a use case.The time series diagram contains 4 elements, namely the object (OBJCE), the Lifeline (Lifeline), the message, and the activation (Activation).Time series diagrams in UML are rep

In the 13 graphs of UML 2.0, class diagrams are one of the most frequently used UML diagrams. Martin Fowler in his book "UML Distilled:a Brief Guide to the Standard object Modeling Language, Third Edition" (UML Essence: A concise reference to the model language South (3rd edition)) There is a paragraph in this: "If som

(representing 0 or more), "0,1" (for 0 or one), "N...M" (for N to M), "m...*" (for at least m).• Association Relationship (association) is the most commonly used relationship between classes and classes, which is a structured relationship between a class of objects and another class of objects. • In UML class diagrams, objects that are associated with a solid line are connected by a class that, when implemented in a programming language

For inheritance, subuse cases include all the content of the basic use case and its relationship with other use cases or participants; Example of a use case chart: Complaints: I feel that the use case diagram is not mature enough to express the requirements of the system. Users without a UML background almost do not know w

PHP and UML class diagrams PHPandUMLClassDiagrams. This short article is well written. it can be said that using PHP to explain UML (or conversely) is an innovation. through this article, I also found a good site: www.phppatterns.com. This short article on various UML techniques is well written. using PHP to explain UML
