What charts and the functions of each diagram are included in the UML object-oriented model? 1. describes the design process of Object-Oriented Analysis Based on UML. 1. Identify system use cases and RolesFirst, conduct a Demand Survey on the project. Based on the busi

the UML, which has been studied for so long, has a certain understanding of UML. Now a small sum, if there are mistakes, I hope you correct me. Learn together and make progress together. "What is UML?" "UML (Unified Modeling Language) Unified Modeling Language, is the standard modeling language for software and sys

First, create an xml file. The resource type is drawble and the root element is shape. I. Custom draw lines You can use the textview control in the layout xml file to set the background attributes. Ii. Custom circle Use the imageview control in the layout xml file 3. Customize the rectangle 4. Use custom Fonts Copy the font format file. ttf to the assets Directory, read the font file Typeface. createFromAsset, and set the type setTypeface. T

preceding entity, the class diagram establishes three tables, establishes the new project, the source code is as follows:--Create Database newssystem--1, set up Category table CREATE TABLE category ( ID int identity (primary) key, [name] varchar () not NULL )--2, creating news Table CREATE TABLE news ( ID int identity (primary) key, title varchar (+) not Nu ll, [content] text NOT NULL, createtime datetime NOT NULL, caId int )--3, build Comment table create TABLE comment ( C13/>id

objects. Code is not a member of a class, but a parameter or local variable of its method. Aggregate (... owns ...), combination (... is a part ...), are associated (... has ...). However, Association tends to be the relationship with two independent and equal things, such as a good friend or a good friend. However, aggregation and combination tend to be the relationship between the whole and the part. The difference between aggregation and combination lies in the overall grasp of some lifecycl

Tags: perm code recognition Considerations Impact Technology sharing position another implementation class Brief introduction Class diagram is the core of object-oriented analysis and design, which is used to describe the relationship between class and class, interface and interface, class and interface in each module of the system, as well as the properties and operation of each class, which are generally implemented in the detailed design process. The class diagram itself is the abstract of t

In the course of learning to use a number of block diagrams, for drawing block diagram of the language is numerous, this article will be used in the study of a drawing block language to do a simple introduction.Go straight to the subject, using a visual object-oriented Modeling language---UML,UML uses some standard circular elements to represent the object model intuitively, so that people like building wor

Shape object from the shape factory.3. A shape factory creates a Shape object.4. The artboard calls the Shape object painting method to draw the shape.Collaboration diagram (Cooperation Diagram): Describes the interaction between objects, can visually display the collaboration between objects, and timing diagram is called the interaction diagram.State Transition Diagram: Describes all possible states of an object and the transition conditions that re

If the company and the Department is a whole and part of the relationship, no company there is no department.A combinatorial relationship is a relationship that is stronger than the aggregation relationship, which requires that an object representing the whole in an ordinary aggregation relationship is responsible for the life cycle of the object that represents the part."Code embodiment": member variableArrows and points: solid lin

dynamically. The behavior diagram is used to describe the dynamic behavior of the system. UML behavior diagram includes: use case diagram, activity diagram, state machine diagram, interaction diagram (interaction diagram includes: sequence diagram, communication diagram, interaction overview diagram, Time graph ).Development tools:There are many development tools for UML that can
