自己使用springMvc+myBatis+oracle数据库的一个小例子，实现了增，删，改，查，分页功能，带有sql,适合初学者

为了得到最大的性能，一般数据库都有并发机制，不过带来的问题就是数据访问的冲突。为了解决这个问题，大多数数据库用的方法就是数据的锁定.-In order to get the maximum performance, a general mechanism for the database have complicated, but the problem is caused by data access conflicts. To solve this problem, the majority of the database is used to lock data.

这里我举函数的例子。如何在pl/sql中创建函数和调用函数

真受不了，还要解释，就是一些cobol的东东啦，看看就会晓得了嘛-really hollered, but also explained that some of the COBOL-- Wanton, will look at the know! !

初始化数据库 设置用户入库界面 使读者对数据库有一定的了解-initialization warehousing database user interface to the database so that readers have a better understanding

通用数据库格式转换工具，支持oracle,sqlsever,access等数据库之间数据格式转换:即Oracle转SQL Server；SQL Server转Oracle；Oracle转Access；Access转Oracle；SQL Server转Access, Access转SQL Server等。可以实现数据库的移植，异构数据库之间同步。完成表的创建（含字段的约束：默认值，是否为空，和的主键），数据的导入，导出。转换速度快，有完整的转换日志，有那个数据无法转换，可以精确定位。-Common database format conversion tools in support of oracle, sqlsever, access and other data format conversion between the database: the Oracle to switch SQL Server SQL Server switch to Oracle Oracle switch to Access Access switch to Oracle SQL Server switch to Access, Access switch to SQL Server and so on. Database migration can be achieved, synchronization between heterogeneous databases. Complete the table creation (including field constraints: the default value, whether it is empty, and the primary key), data import, export. Conversion speed, a complete conversion of the log, there is that data can not be converted, you can pinpoint.

说明：  解决delphi下增对Oracle数据库开发时碰到的无法更新定位问题(Under the settlement by delphi on Oracle database development can not be updated when the positioning of encounter)

暂时只能安装12cR1，安装12cR2时会有问题

改源码用来对Oracle性能进行测试，请各位指教。-Source used to test the performance of Oracle, please advice.
