The recent learning architecture design, first from the most basic student information management system analysis. Objective: The structure design of student information management system First step: Identify system complexity?? The real purpose of architecture design is to solve the problems caused by software complexity, so we should first identify the complexity of the system, and then analyze the

There is a student table with three columns in total. The first column is the student ID column, which stores the student ID of the Course Selection. You can repeat it to allow one student to select multiple courses. The second column is the course column, that is, the name of the course selected. The third column is

Some time ago, a friend of Android just wanted to implement a table to show the information, so we can extend the viewgroup to achieve a simple.This article through the extension of Android ViewGroup implementation table can be used for course information, Student Information view display, the implementation of the table is available in a patchwork layout can also be customized viewgroup way to achieve.The final effect is as follows:Start by creating
