数据库的应用，基于索引，实现一个简单的B+树搜索树

题目:稀疏矩阵是指那些多数元素为0的矩阵.利用稀疏特点进行存储和计算可以大大节省存储空间,提高计算效率.实现一个能进行稀疏矩阵基本运算的运算器.基本要求:以带行逻辑连接信息的3元组顺序表表示稀疏矩阵,实现两个矩阵相加,相减和相乘的运算.矩阵的输入形式采用3元组表示,而运算结果的矩阵则以通常的阵列形式列出.概要设计:1.以带行逻辑连接信息的3元组顺序表表示稀疏矩阵2.本程序包含2个模块:(1) 各集合定义模块(2) 主程序模块-topics : sparse matrix refers to those elements for most of the matrix 0. Using sparse features storage and computation can be greatly reduced storage space and improve computational efficiency. One can achieve for sparse matrix operations basic computing device. Basic requirements : OK logical connection with the three yuan Information Group the order said the sparse matrix table to achieve two matrices together, subtract and multiply arithmetic. Matrix entry forms using three yuan Group said, and the results of the matrix operations while the usual array listed. summary of design : 1. in line with the logic of information linking the three element group said sparse chronology matrix 2. this program contains two modules : (1) Set module (2) main program module

We discussed two versions of the 3-sum problem: A "naive" implementation (O(N^3)) and a "sophisticated" implementation (O(N^2 lg N)). Implement these algorithms.  Your implementation should be able to read data in from regular data/text file with each entry on a separate line.

基于数据库设计一个网页,实现基本功能：增删改、查询、统计报表的功能要有.管理信息-A. General Queries- The system should be able to retrieve useful data stored in the database. B. Statistics Collection- The system should be able to generate useful statistics information. C. Modification of Data- The system should provide interface for the store managers to add, remove and update the data in the database. D. Dealing with special events in the system. Your system should be able to handle real life situations that may arise from running the business. E. You are required to implement a web user interface for your system. F. The user interface should be intuitive and effective to use. G. Please bear in mind that a casual user should not have problems to check some simple information. H. The system should provide an English UI. You can also design multi-lingual UI.

功能实现：1).输入，显示各个学生信息 2)．根据学号，姓名查找某个学生的成绩 3)．修改学生信息 4).删除学生信息 5） 清空数据库6）选择范围的输出学生成绩排名。-Function achieve: 1). Input, display individual student information 2). According to Student ID, name to find a student" s achievement 3). Modified Student Information 4). Remove Student Information 5) Clear the database 6) Select the output range of student achievement rankings.
