摘 要
随着计算机技术的飞速发展,原始以纸和笔来记录数据的手段不可避免的会被淘汰,通过计算机来记录和存储数据必然会将其取代,利用计算机可以将许多繁琐的工作简单化,针对油田来说,为了安全和利润,需要时刻监视每口井的参数,而困难在于数据量的庞大,使工作人员陷入了数据录入和记载繁琐的困境,由于大量的数据实时的需要记录,出错变得不可避免。
基于此本文设计一套数据查询和管理系统,通过计算机来存储,查询,并修改数据,前台用Visual Studio 2010构建查询界面,采用C#编写后台代码,用oracle存储数据,通过登录时对权限的设定来划分使用者级别,通过树状图添加节点的方式来显示数据,以按钮事件下编写代码的方式来调用SQL语句查询数据。
该系统主要由两大部分组成,一个登录界面和一个查询显示界面。登录时只需选中一个用户权限,就可以自动添加所有信息,简单快捷,菜单栏下的数据操作选项可以增加,修改,删除数据,使用户和数据库具有交互性。

Abstract
With the rapid development of computer technology, the original means of pen and paper to record data will be eliminated inevitably,these must be replaced by computer to record and store data,a lot of tedious work can be simplified by a computer,for Oilfield, in order to the secure and profits,the parameters of each well need to be monitored constantly,the huge amount of data make staff fall into the dilemma of Data entry and records,because of large amounts of data in real time need to be recorded,error becomes inevitable.
Based on this a management system has been designed,data can be stored,queried,modified by computer,the query interface was build by Visual Studio 2010,the background code was written by C#,data was stored by oracle,the different user levels were divided by the setting in login form,the data was displayed by adding nodes on treeview,the code was written for using SQL to query data.
The system was consisted by two major components,a login screen and a query screen.All the information will be added automatically by only selecting one login privileges.data can be added,modified,deleted by the options on the menu,making users and database interactive.

Key words: oracle; SQL Sentence; query dynamic data; Visual Studio 2010
