as alternative streams in the parent case. For example, there may be many tasks that require approval from department leaders in the business, but the approval process is very similar. In this case, the general relationship can be expressed as follows: The above is an article I have referenced. I think the difference between the three relations is very clear. Based on this, I will combine my own system to explain the project (Online Shopping System) as a whole. ********************************

a lot of computer technology books or articles commonly used in UML class diagram, the author of the book describes each design pattern is the class diagram + Object-oriented language applet ( in C #, its basic knowledge of a different article)+ character dialogue interpretation of knowledge points. This paper introduces the basic knowledge of

Teach () { ...... } } 4. Interface and Implementation relationshipIn many object-oriented languages have introduced the concept of interfaces, such as Java, C #, etc., in the interface, usually no attributes, and all operations are abstract, only the operation of the Declaration, there is no implementation of the operation. UML represents an interface in a manner similar to the representation of a class, as shown in 3:Figure 3

. Note: The door in "Top level diagram" uses the message arrow to point to the reference fragment, where it is not necessary to draw it as a block.??Partial decompositionAn object can draw multiple lifelines so that messages inside and between objects are displayed on the same graph.State Constants/ContinuationsThe state constant is the constraint of the lifeline, and the runtime is always true. A rectangle displayed as a semicircle on both sides, suc

and is considered an attribute in another local application.(2) The same entity does not have exactly the same attributes in different detail views, or the order of the attributes is not identical.(3) The relationships between entities render different types in different detail views. For example, the entity E1 and E2 are many-to-many links in local application A, but in the local application B is a one-to-many connection, as in the local application of x E1 with E2, and in the local applicatio

definition of sequence diagram: Interaction is the behavior of a group of messages that interact with a set of objects that implement a goal in a specific context. Sequence diagram is a kind of interaction graph. A sequence diagram is a visual representation of the time order in which messages are routed between objects. Sequence diagrams describe the needs of u

This article begins with a discussion of code-level issues.

select from the list. Delete the re-Warranty notification without affecting the plan.6. There is an aggregation relationship between cutover notification and request ticket. Similarly, a request ticket can exist independently of a cutover notification. That is to say, the cutover notification is deleted without affecting the ticket.7. Notifications and replies are in a combination. Because the reply cannot exist independently of the notification. That is to say, to delete a notification, the co

arrows can only be nouns or noun phrases, and the entire graph does not reflect the order of execution of the processing.③ generally do not draw material flow. Data flow reflects the data that can be processed by computer, it is not physical, so the flow chart of the target system is generally not to draw material stream.④ has at least one input data stream and one output stream per processing, reflecting the source and processing results of this processing data.⑤ number.

When you use Microsoft Visio to draw a use case diagram today, you find that the include relationship is not found in the Visio UML use case, which is the "arrow" + "Finally, a workable solution was found:First: Open the UML Model diagram, software and database, Microsoft visio-> newThen select "
