complete. Significant progress has been made in serialization logic modeling due to changes in the symbol set of the sequence diagram in UML 2 ). Note the text I mentioned above: "The uml2.0 draft Specification has been adopted ." Indeed, the specifications are still in the draft State, but the key is that the draft specifications have been adopted by OMG, which is an organization that uses them until the new standards are quite reliable. Before UML
UML-united modeling language, unified modeling language-is an object-oriented visual modeling language. UML uses a set of visualized graphical symbols (such as class diagrams) as the modeling language. These symbols can be used to visually describe all aspects of the system. UML describes a model by establishing various relationships between graphs (such as the relationship between classes. There are 5 types (9 types) of diagrams in UML, includingUse case di
The main purpose of this article is to continue to focus on the basic UML diagram. This month, we will learn more about the sequence diagram. Note that the following example is based on the new UML 2 Specification. Purpose A Sequence Chart is used to display the interaction between objects in a series of order of interaction. Like a class chart, developers generally think that a sequence chart is only meani
Activity diagram Activity diagram (dynamic diagram) is a workflow that clarifies the implementation of business use cases. Activity diagram in Business Case Model The Business Use Case workflow describes the work that must be done by the business to provide the required value to the Service's business leading role.

A : the use of E-R method for database conceptual design, can be divided into 3 steps: First, the design of local E-R mode, and then the local E-R model integrated into a global E-R mode, and finally the global E-R mode optimization, get the final E-R mode, that is, 1, a university realizes the credit system, the student may choose according to own circumsta

Use the [iconix] method to design a blog [sequence diagram] In the previous articles, we performed domain model and case modeling respectively, and used the robustness tool for further analysis and verification.Based on the corresponding model (domain model), the related boundary pair is introduced through the robustness method.Control Object (Controller), and update the attributes (fields) of classes in the corresponding domain model ). Next, you
A component diagram is used to reflect the physical structure of the Code. From the component diagram, you can understand the compiler and runtime dependencies between software components (such as source code files or dynamic link libraries. You can use a component diagram to divide the system into cohesion components and display the code structure. The main purp
behavior and achievesSpecific interface. 1In component-based development (CBD), component diagrams provide architects with a natural form of starting to model the solution. The component diagram allows an architect to verify that the required functions of the system are implemented by the component.Ensures that the final system will be accepted.In addition, component diagrams are useful communication tools for different groups. The
Collaboration diagram of UMLCollaboration Diagram--communicationdiagram also called co-operation diagram, is an interaction diagram (Interactiondiagram). The emphasis is on the organizational structure between the objects that send and receive messages, and a collaboration diagram

A sequence diagram describes the interaction modes between objects in chronological order. It uses the "lifeline" of objects and the messages passed between them to show how objects participate in interaction. A sequence diagram is a model used to describe how object groups collaborate in certain behavior aspects over time. A sequence diagram captures the behavi

to represent other information, such as comments and semantics of model elements. In addition, UML provides an extension mechanism that enables the UML language to adapt to a special method (or process) or expand to an organization or user. Classification of UML views:UML is used to describe a model. A model is used to describe the institutional or static features of a system, as well as behavior or dynamic features.

I still cannot get through it, # ￥ % ^ % ￥ #)Miao Zi got the car and the antenna system was damaged (no land Network !), At this time, the standing wave ratio will be very high. That is to say, most of the power is reflected back to the vehicle platform, and little power is emitted. At this time, the car is definitely not comfortable, people are not comfortable, because you are not sure about how much radiat
From:http://www.uml.org.cn/oobject/201211231.asp 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: Concise Reference of standard object Modeling language South (3rd edition)), there is such a paragraph: "If someone were to come," "a dark alley and say, ' Psst, Wanna, a UML diagram?
