企业重要办公数据信息管理系统设计-VB(论文+系统+开题报告+答辩PPT)

--------------摘要--------------

随着科学技术的迅猛发展和管理水平的不断提高，计算机已经被广泛应用于日常管理之中，它的运用不断改进着管理模式，使管理日趋程序化、规范化、现代化。对一个企业来说，为了使数据在企业中能更有效的被利用、被管理，引入计算机辅助管理已是一种必然，企业管理信息系统的开发迫在眉睫，其中为企业实施全面质量管理，落实技术经济责任制提供及时、准确、可靠和一致的信息，企业数据信息管理系统成为企业管理系统中的重要组成部分。
本系统主要实现了以下功能①数据录入：用户按照所需要的工程规格输入条件，系统根据条件按照最底层数据表计算出本次操作所需的数据加载到事先设置好的空数据表中。②数据查询：用户给定查询的数据条件，系统在查询DBGird中示出查找到的数据。同时可把数据添加到专用表，进行多工程的数据管理。③数据汇总和报表功能：根据企业实际要求出汇总的数据的报表显示，同时汇总完成的信息可以打印成报表，用于文件存档或者便于企业管理者管理数据信息。④物理表管理：对物理表进行添加、修改、备份和删除等工作，便于数据库的长期正常运行。⑤系统权限维护：在登陆进系统时有权限的要求，高级的权限可以管理低级的权限，加强了企业信息的保密工作。
本系统的开发使用 MICROSOFT公司的 VISUAL BASIC作为开发工具,利用其提供的各种面向对象的开发工具,尤其是数ADO技术能方便而简洁操纵数据库,通过这些技术在短时间内建立系统应用原型,然后,对初始原型系统进行需求迭代,不断修正和改进,直到形成了这个用户满意的可行系统。

-------------ABSTRACT--------------
With science and technology swift and violent development and constant improvement of the management level, the computer has already widely used in everyday control, its application updates the management mode, enable managing the procedure , standardizes , modernization day by day. To an enterprise, for make data can a valid one utilize , manage among enterprise, it has already been a kind of necessity to introduce the computer-aided management, the development of the management information system of enterprises is extremely urgent , among them implement the total quality control for enterprises , implement the technological economic responsibility system and offer prompt , accurate , reliable and unanimous information, enterprise's data information management system becomes the important component in enterprise's administrative system
This system has realized the following function mainly ①The data are input: Users input the condition according to the project specifications needed, system is it operate according to terms necessary data is it get in advance setting up kind empty data listing to load this time to calculate out according to the bottom data list. ②The data are inquired about: Users give the data terms inquired about definitely, the system shows the data that finds out in inquiring about DBGird. Add the data to the special-purpose form at the same time, carry on the data management of many projects. ③The data are gathered and report form function: Demand according to enterprise report form of data gathered to appear show message finished to gather at the same time can be typed into a report form actually, used in the file files or a convenient enterprise's administrator manages the information of the data④Watch manages physics: Go on add , revise , back up and work of deleting etc. to physics form , benefit the long-term normal running of the database. ⑤The systematic authority is safeguarded: There is a demand for the authority while landing and entering the system , can manage the low-grade authority in advanced authority , have strengthened the security work of enterprise's information

The development of this system uses VISUAL BASIC of MICROSOFT Company to utilize its various kinds of target -oriented developing instruments offered as the developing instrument, count ADO technology can convenient succinct to handle database , set up through technology the system use the prototype within short time especially, then, carry on the demand to change and take the place of to the initial prototype system , is revising and improving constantly, until forming the feasible system that this user is satisfied with.

Keyword:Administrative system , project , controlling part,ADO
