uml modeling software

Requirements gathering is an indispensable step in any successful software development cycle. Although there are a number of requirements collection methods, the most common method is use case modeling. In the previous two columns, we have completed part of the work of associating sequence diagrams with use case modeling. This time I will talk more about the theo

subsystems. VI,Example In the book management system, the staff can maintain (add, delete, and update) reader information, and maintain book information. Readers can request to borrow, return, and renew books through the Book Administrator, readers can log on to and query books and borrowing information. The example graph is provided.

. Manage documents This type of documentation is developed by software developers during software project development and should be submitted to some work plans, work plans and work reports of the management department. By reading these documents, managers can learn about the schedule, progress, and resource usage of software project development activities. Such

In order to successfully develop a project, you need the correct process, tools, and symbols (annotations). In this article, the authors explain how UML provides you with the right process for providing you with symbols, the rational Unified Process (Unified process), and how rational rose provides you with the tools to make your project successful. What is visual modeling? Visual

, the aggregate object is responsible for the life cycle of some objects.7. the connotation of the extend relationship between use cases in use case diagrams:The extended relationship between use cases is used to model the user as part of a use case that is considered an optional system behavior. In this way, the optional behavior can be separated from the required behavior.8. Generalization relationships describe the ability of a participant to complete another participant's and can supplement

variable name and its class type in the box in the horizontal axis direction, as shown in Figure 2. This form does not include loops, conditions, and branches that are common in conventional forms. In the actual control process in the system, some assertions made during the interaction may be false. If the assertion is found to be false, all messages in the instance sequence diagram are empty, and this situation will not occur. An instance sequence diagram describes a single situation that may

various diagrams1. Static diagram: Use case diagram, Class diagram, object graph, Component diagram, deployment diagram2, Dynamic diagram: state diagram, activity diagram, time series diagram, collaboration diagramThird, the UML system design steps1. Requirement Analysis and description (use case diagram)2, according to the requirements of the establishment of a system of static model (class diagram, object graph, Component diagram, deployment diagra

Document directory The UML use case diagram contains three relationships: (include), (extend), and (generalization ). Overview The Use Case attempts to summarize the relationship between roles and systems in the use case, and describes the functional requirements of the system, the interaction between roles and systems, and the system response. Official definition: Use Cases define a set of use cases, each of which is a series of operations perfo

the interface of the component implementation. The introduction of interfaces is the interface used by the components. Six, the significance of the component diagram(1) The source code is modeled, it can be divided into several modules or subsystems to be processed.(2) Modeling the relationships between executables, which can clearly describe the dependencies between executables. Seventh, the drawing of component drawing(1) To determine the external

Recent requirements and designs for writing projects require UML modeling, previously used in Visio, although Visio also provides a number of UML components, but it's always uncomfortable to use. Today, IBM's rational Rose was downloaded, referring to a number of articles for installation, which documented the entire installation steps and installation problems a

or describe other features such as composite aggregation, navigation, judgment, association classes, and special categories of dependency and generalization relationships. These and many other features can be expressed in UML, but they belong to a deeper concept.Dependencies, generalizations, and associations is all static things defined at the level of classes. In the UML, these relationships is usually v

plantuml--Simple and fast UML editing software for EclipseIntroduction: in the application system software development process, if the software is composed of many objects, its structure is difficult to clarify by virtue of analysis, at the same time in order to facilitate the development and reuse of

artifacts must be on the nodes that correspond, rather than being isolated. iv. Explanation of the deployment diagram(1) Node: the common name of the compute resource. Includes processors and devices. Where the processor is the hardware structure that can execute the program, such as computers and servers. A device is a service that is performed externally through an interface, such as a printer. Each node should give the appropriate tag description, such as operating system, vendor, and so on.
