sql小型

1. 学习sql有什么用，具体用于什么方面

SQL用于存储数据，做一些管理系统，网站什么的，都会使用sqlserver来存储数据，SQL的作用：

SQL主要用于数据库系列的软件的查询、汇总、写入、删改等方面的操控，具体应用于数据库编程或数据库数据的维护。

也就是说SQL一般用于数据库编程，以及现有数据库错误排查。所以一般涉及数据库的编程人员或电脑信息化系统维护人员需要对SQL（也就是对数据库）知识进行学习。

(1)sql小型扩展阅读：

结构化查询语言是高级的非过程化编程语言，允许用户在高层数据结构上工作。它不要求用户指定对数据的存放方法，也不需要用户了解具体的数据存放方式，所以具有完全不同底层结构的不同数据库系统, 可以使用相同的结构化查询语言作为数据输入与管理的接口。

结构化查询语言语句可以嵌套，这使它具有极大的灵活性和强大的功能。

3. MSSQL适合做个人小型软件的数据库么

1、MSSQL，不管网络的单机的，都适合。2、是要装，一般都是把安装脚本写好，跟你的应用程序一起打包装的。3、ACCESS对生成的安装包比SQL要简单，至于要安全，数据部分可以用MD5算法加密，再写进数据库里。

4. SQL SERVER 算是一个小型的信息系统吗请具体一下。还有就是小型信息系统还有哪些

SQL SERVER 是数据库，如果自己开发的信息系统需要存放数据，那就可以使用该数据库进行存储数据。
销售管理信息系统是一个信息系统，但是大型还是小型要看具体的业务，如果只是简简单单的登记销售记录。查看信息等，那就只能算小型的。以此类推，图书管理系统、学籍管理系统、车辆管理系统等。

5. 如何用prontpage和SQL设计一个小型的数据库系统(学生综合测评排名系统)

首先在SQL中利用企业管理器或向导建立一个数据库，命名为学生管理系统， 启动SQL Sever服务，运行企业管理器，单击要创建数据库的服务器左边的加号图标，展开树形目录，在“数据库”节点上右击鼠标，在弹出的快捷菜单中选则“新建数据库”命令，然后按照提示一步步建立数据库，不再详细叙述。 假设学生管理系统下有三个表，分别为学生表、课程表、修课表，表的结构
