many properties, but do not use the idea of designing a database to design class diagrams. Class diagrams are only used to reflect the reality that when designing a class diagram, you can think of the data as stored in a DB or stored in XML or stored in a file, not to consider storage. Object graph, not too much to use Sequence diagrams, which describe the order of interactions between objects, focus on the chronological order of message passing between objects, which is useful, but not

monkeys are animals, but we can't say that monkeys are animals classified by purpose. Note here that "primate is an animal classified by purpose" is classification. So note that the "yes" relationship here is not all generalization.2. Sequence diagram (Sequence Diagram)Sequence diagrams are one of the interaction diagrams (Interaction Diagram). Interaction diagrams describe certain behaviors between objects (note that between objects, not classes. It is also possible that there is more than jus

A friend of the reflection, a direct talk about the design mode even if the understanding, and do not know how to draw a class diagram, then we will use a graph to illustrate how to apply UML to correctly represent the relationship between class and classes. This picture tells the whole story about the survival of birds. The first is the class: in UML, we us

Most computer systems today are in some sort of network. Most systems provide some value or service to entities other than the group, in addition to serving the internal user community. In return, most systems also use services provided by other systems (for example, client-side operating systems, WEB browsers, external databases, and Third-party service providers). With the advent of WEB services, we will soon find that the systems we develop are serving a growing range of applications. In thi

UML, English name Yue: Unified Modeling Language, she also has a Chinese name is called Unified Modeling Language, in simple terms, she is a drawing software blueprint standard language. Her ability to express is particularly strong, describing the various views needed for development and then deploying the system on that basis. UML is a difficult way to develop software development methods, she is indepen

A package diagram can consist of any UML diagram that can hold elements such as classes, interfaces, components, use cases, and other packages. A package is a very common element in

UML is not a new term, but it is rarely used in practice (it may be because it is used for small projects, so it is much used for large projects ). UML is a good thing, but it is not a good thing to rely too much on UML, because sometimes it will complicate simple things. even the fine structure and reusability of Code cannot be used as an excuse to force the use

I. Meanings and functions of the Unified Modeling Language (UML: A: uniied modeling language: Unified Modeling Language, simple Simply put, it is a language with special purposes. UML (Unified Modeling Language) is a tool for analyzing and designing software using object-oriented methods. UML is a language used for Visual Modeling of software systems.

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. The translation of various UML terms comes from the book I am reading, TheUnifiedModelingLanguageUserGuide. UML (UnifiedModelingLanguage) is a good short article. using PHP to expla

Rose, a design tool that was developed directly from UML, was created to support UML modeling, and rose did not support database-side modeling at first, but has joined the database modeling feature in today's release. Rose is mainly in the development process of various semantics, modules, objects and processes, state and other descriptions are better, mainly reflected in the ability to analyze and design f

describe complex program logic or multiple parallel transactions. A collaboration diagram is a graphical representation of the related interactions between objects, and can also have hierarchies. Multiple objects can be used as an abstract object, through decomposition, using the lower-level collaboration diagram to express the collaboration between the multiple objects, which can alleviate the complexity of the problem. using the ER to draw collabor

static structure of the system. Process view and physical view are mainly used to describe the dynamic structure of the system. Not every system must draw five views, but each has its own focus. For example, the MIS system focuses on the logic view and development view, while the real-time control system focuses on the process view and physical view. We usually choose UML to present various views. The foll

Original: UML First glanceThis chapter uses a simple example to take a first glance at the concepts and views used in UML. The purpose of this chapter is to organize high-level UML concepts into a series of smaller views and diagrams to visualize these concepts, explain how to describe a system in a variety of different concepts, and how to organize the various v
