Additional questions: Deployment diagramKey concepts:1. The deployment diagram shows how specific software artifacts, such as executables, are assigned to a compute node (something that has a processing service). The deployment diagram represents the deployment of the software elements on the physical architecture , as well as the communication between the physical elements (usually over the network).2. The

10. Status machine diagram state machines diagramA state machine diagram is a common technique for describing a system's behavior. In an object-oriented approach, a state machine diagram is drawn for a single class to demonstrate the life cycle behavior of a single object.See Figure 10.1The diagram shows a state machin

I think the correct sequence of Data Center reconstruction is: database, drawing (package diagram, class diagram, timing diagram), and the implementation of code at the end of the document. However, although I think so, I did not fully follow this process. In my opinion, the Plan and sequence are dead, and people are living. What if you do not go down after a cer

Unified Modeling Language (UML. It includes the following important functions: Visualizing) Specifying) Construting) Document creation (documenting) UML includes: User case diagrams) Class Diagrams) Sequence Diagram (sequence diagrams) Collaboration diagrams) Activity diagram (activitiy diagrams) Component diagram (Component diagrams) Deployment Dia

DFD graph is a ing method based on the closeness of data and data. It is a structured analysis method from the problematic space to a certain representation. DFD diagram plays an irreplaceable role in software requirement analysis. DFD diagram is mandatory in the soft examination, and is also a very important diagram in the software engineering. The following is

Transferred from: http://blog.csdn.net/tianhai110Use case diagrams are primarily used to describe the relationship between users, requirements, and system functional units. It shows a model diagram of a system function that an external user can observe."Purpose": helps the development team to understand the functional requirements of the system in a visual way.The use case diagram contains the following ele

It is important to clarify the relationship between use cases when drawing a use case diagram. The relationships of use cases include generalization, extended, and include ). Include and extend are the most confusing. Next we will thoroughly clarify the relationship between the three Based on the instance. Basic ConceptsUse case diagram: the use case diagram show

fluctuations caused by special causes are more likely to be discovered, for example, if the limit is exceeded or the lower limit is exceeded, or the control chart is usually used to determine the seven-point rule. The role of a control chart is to discover these exceptions and take corrective actions to analyze the root cause. Use and selection of Control Charts Continuous grouped data: xbar-r control chart and xbar-s control chart. Continuous single value data: I-MR control chart. Number o

Activity diagram, her English name is active Diagram, a workflow that describes the implementation of a business use case, which is one of the none of the diagrams used in the UML family to model dynamic aspects of the system. To give a simple example, to build a work flow for example, first of all, we have to select an address, and then commissioned an architect to design the house, when we have confirmed

Introduction The learning of UML started on the 3rd and ended on the evening of the 13th. Today (Nov 14), I reviewed UML and refined the following learning tasks. The overall learning of UML is similar, but there are still many areas to be improved. Learning Process At the beginning of UML learning, I first spent half a day on the concept of UML. The main method is to query materials and watch books online, and then watch the UML video, during the watching process, I watched the video quickly. A

Most of the models in UML describe the logic and design information: Use Case chart to understand expectations Class diagrams can understand the Vocabulary (class and object) of the problem domain) The status chart, InterAction diagram, and activity diagram can be used to understand how the words in the class diagram are written (logical structure)An Implementati

I started to draw the UML diagram from June 1. Now it's over a month and a half! Let's talk about my feelings with UML diagrams over the past one and a half months: Phase 1: September 5-September 5 1. Example Diagram The use case diagram mainly refers to the functional model diagram of the system, and has the first dra

Sequence diagramA sequence diagram is a form of an interaction diagram that shows the evolution of an object along a lifeline, and the interaction between objects over time is expressed as a message from the source lifeline to the target lifeline. The sequence diagram is a good indicator of how those objects communicate with other objects, what messages trigger t

In This article, we focus on UML time series diagrams, which include modeling elements in the main sequence diagram: Objects (Actor), lifelines (Lifeline), Focus control (Focusofcontrol), messages (message), and so on. First, the UML sequence diagram Brief introduction (Briefintroduction)time series diagrams (Sequencediagram) are graphs that display the interaction between objects, which are arranged in

Activity diagram is one of the 5 dynamic modeling mechanisms of UML, is a process-oriented description, and describes the workflow of business use case implementation. The activity diagram is also a special example of the state machine, emphasizing the sequence and concurrency steps in the calculation process, where most of the state is active, and most of the transitions are triggered by the completion of

The e-r graph , also known as the entity-contact graph (Entities Relationship Diagram), provides methods for representing entity types, attributes, and connections to describe the conceptual model of the real world.1 , Presentation methodE-r is an effective method to describe the conceptual structure model of the real world. is a way to represent a conceptual model.(1) Rectangle: Indicates the entity type, the name of the entity is indicated in the re

UMLThe use case diagram is a very useful graph. In demand analysis, it can free people from the heavy documentation, in addition, it prompts people to express their meaning more accurately and intuitively when making demands. Common languagesThe word is often unable to express a thing clearly. At this time, it needs to be expressed in other ways. The example graph is a good method, of course, the use case diagram
