I need a little of help. This is my design to organize several categories. Category 1 Sub Category 1.1 Sub Category 1.1.1 Sub Category 1.2 Sub Category 1.3 It would be a collection. I want to store it in a database, but I don't know how can I model it in a database table. I'm using SQL Server CE. UPDATE : I forgot put the objective number in the class (1.1, 1.1.1). You'd have a table something like this: category id (primary key, not null) name (text, not null) parent_category_id (foreign key to category.id, nullable) Then, if a category has a parent, you reference the id of that other row. So

这周做的事 继续自学UML和java； 去pta平台练习基础编程； 学习html; 每天坚持阅读 下周将做的事： 1.进入PTA平台进行程序的编写； 2.阅读java程序设计 用java实现一些 复杂 的程序; 3.每天自学1-2个小时的JAVA; 4.自学html和UML; 来源： https://www.cnblogs.com/zzmds/p/11407405.html

　　本周每天都敲了2-3道PTA的题，目前PTA所做题目分数已达到老师的要求。并且预习了部分建模语言UML的知识。 　　下周要看完UML，进一步学习JAVA的知识。 　　本周遇到的问题是不清楚JAVA中对类和方法的限定的适用场景。 来源： https://www.cnblogs.com/wuren-best/p/11407029.html

How can I show struct members in the UML class diagram. In class diagram, I added struct as attribute and don't know how to add 'x', 'next' elements to that struct. if I generate the C++ from class diagram, it should have 'x' and 'next' elements in struct. class LinkList { private: // how to show the struct and its members in UML class diagram struct node { int x; node *next; }*p; public: // add an element void append(int num); // counts number of elements int count(); }; something like this?! and you would just remove the <<ptr>> stereotype and use the * as well, like +next:node* 来源： https:/

I have the following interface: public interface IRegisterable { T Register<T>(string username, string passw) where T : User, ICanLogin, new(); } User is an abstract class, and ICanLogin is another interface. Now, I want to represent the above interface with its method in a UML Class Diagram, in Visio. How can I represent the above generic method with its constraints in a Class Diagram ? UML does not support type parametric methods directly. About the closest you'll get is to define a nested class which has the type constraints with a stereotype which you will interpret as meaning it's a type

今天离开学只剩一周了，开始了暑假作业的收尾工作，这个暑假要求达到500分的pta上的题，还有要求的实验报告，我这周主要是写完了pta和pta相关的实验报告，还有看了UML的第一章导言，知道了什么是统一建模语言，UML的发展史、UML的结构模型和行为模型，看了第一章的用例图，知道了用例之间的关系，这周没有对Java进行复习，主要是对假期作业的总结和对作业的完成。 来源： https://www.cnblogs.com/1234yyf/p/11405948.html

How do i show the use of static methods in a UML class diagram? class A{ public static void test(){ } } class B{ public void b(){ A.test(); } } How would a class diagram look like, which shows the relationship? UML 2.0 would be prepared, if there is a difference. To show a static method you underline the name of the static method - have a look here for more detailed info. As for navigating that relationship; class B is dependent on the existance of class A . We can say that class B has a "usage dependency" on class A class B ----uses----> class A Hope this helps. umlcat @RobertMS is right.
