2、动人事管理的日常事务，是适应现代企业制度要求、推动企业劳动人事管理走向科学化、规范化的必要条件；计算机管理所无法比拟的优点检索迅速、查找方便、可靠性高、存储量大、保密性好、寿命长、成本低等。这些优点能够极大地提高人事管理的效率,也是企业的科学化、正规化管理,与世界接轨的重要条件。不同的企业具有不同的人事管理制度，这就决定了不同的企业需要不同的人事管理系统。【关键词】人事管理，提高效率，科学化，信息化。在目前市场上这些众多的程序开发工具中，有些强调程语言的弹性与执行效率；有些则偏重于可视化程序开发工具所带来的便利性与效率的得高，各有各的优点和特色，也满足了不同用户的需求。然而，语言的弹性和工具的

3、便利性是密不可分的，只有便利的工具，却没有弹性的语言作支持，许多特殊化的处理动作必需要耗费数倍的工夫来处理，使得原来所标榜的效率提高的优点失去了作用；相反，如果只强调程续语言的弹性，却没有便利的工具作配合，会使一些即使非常简单的界面处理动作，也会严重地浪费程序设计师的宝贵时间。作为数据库系统的开发，Visual Basic是一个非常理想选择。数据库是MIS中的重要支持技术，在MIS开发过程中，如何选择数据库管理是一个重要的问题，目前，数据库产品较多，每种产品都具有各自的特点和适用范围，因此，在选择数据库时，应考虑数据库应用的特点及适用范围，本系统选用的数据库语言Visual Basic语言，该

4、开发工具具有很多长处：Visual Basic是一种可视化的、面对对象和条用事件驱动方式的结构化高级程序设计，可用于开发Windows环境下的种类应用程序。它简单易学、效率高，且功能强大，可以与Windows的专业开发工具SDK相媲美，而且程序开发人员不必具有C/C+编程基础。在Visual Basic环境下，利用事件驱动的编程机制、新颖易用的可视化设计工具，使用Windows内部的应用程序接口(API)函数，以及动态链接库(DLL)、动态数据交换(DDE)、对象的链接与嵌入(OLE)、开放式数据访问(ODBC)等技术，可以高效、快速地开发出Windows环境下功能强大、图形界面丰富的应用软件

5、系统。总的来说，Visual Basic具有以下特点：可视化编程：用传统程序设计语言设计程序时，都是通过编写程序代码来设计用户界面，在设计过程中看不到界面的实际显示效果，必须编译后运行程序才能观察。如果对界面的效果不满意，还要回到程序中修改。有时候，这种编程-编译-修改的操作可能要反复多次，大大影响了软件开发效率。Visual Basic提供了可视化设计工具，把Windows界面设计的复杂性“封装”起来，开发人员不必为界面设计而编写大量程序代码。只需要按设计要求的屏幕布局，用系统提供的工具，在屏幕上画出各种“部件”，即图形对象，并设置这些图形对象的属性。Visual Basic自动产生界面设计

6、代码，程序设计人员只需要编写实现程序功能的那部分代码，从而可以大大提高程序设计的效率。面向对象的程序设计4.0版以后的Visual Basic支持面向对象的程序设计，但它与一般的面向对象的程序设计语言(C+)不完全相同。在一般的面向对象程序设计语言中，对象由程序代码和数据组成，是抽象的概念；而Visual Basic则是应用面向对象的程序设计方法(OOP)，把程序和数据封装起来作为一个对象，并为每个对象赋予应有的属性，使对象成为实在的东西。在设计对象时，不必编写建立和描述每个对象的程序代码，而是用工具画在界面上，Visual Basic自动生成对象的程序代码并封装起来。每个对象以图形方式显示在

7、界面上，都是可视的。结构化程序设计语言Visual Basic是在BASIC语言的基础上发展起来的，具有高级程序设计语言的语句结构，接近于自然语言和人类的逻辑思维方式。Visual Basic语句简单易懂，其编辑器支持彩色代码，可自动进行语法错误检查，同时具有功能强大且使用灵活的调试器和编译器。Visual Basic是解释型语言，在输入代码的同时，解释系统将高级语言分解翻译成计算机可以识别的机器指令，并判断每个语句的语法错误。在设计Visual Basic程序的过程中，随时可以运行程序，而在整个程序设计好之后，可以编译生成可执行文件(.EXE)，脱离Visual Basic环境，直接在Win

8、dows环境下运行。事件驱动编程机制Visual Basic通过事件来执行对象的操作。一个对象可能会产生多个事件，每个事件都可以通过一段程序来响应。例如，命令按钮是一个对象，当用户单击该按钮时，将产生一个“单击”(CLICK)事件，而在产生该事件时将执行一段程序，用来实现指定的操作。在用Visual Basic设计大型应用软件时，不必建立具有明显开始和结束的程序，而是编写若干个微小的子程序，即过程。这些过程分别面向不同的对象，由用户操作引发某个事件来驱动完成某种特定的功能，或者由事件驱动程序调用通用过程来执行指定的操作，这样可以方便编程人员，提高效率。访问数据库Visual Basic具有强大

9、的数据库管理功能，利用数据控件和数据库管理窗口，可以直接建立或处理Microsoft Access格式的数据库，并提供了强大的数据存储和检索功能。同时，Visual Basic还能直接编辑和访问其他外部数据库，如DBASE，FoxPro，Paradox等，这些数据库格式都可以用Visual Basic编辑和处理。Visual Basic提供开放式数据连接，即ODBC功能，可通过直接访问或建立连接的方式使用并操作后台大型网络数据库，如SQL Server，Oracle等。在应用程序中，可以使用结构化查询语言SQL数据标准，直接访问服务器上的数据库，并提供了简单的面向对象的库操作指令和多用户数据库

10、访问的加锁机制和网络数据库的SQL的编程技术，为单机上运行的数据库提供了SQL网络接口，以便在分布式环境中快速而有效地实现客户/服务器(client/server)方案。动态数据交换(DDE)利用动态数据交换(Dynamic Data Exchange)技术，可以把一种应用程序中的数据动态地链接到另一种应用程序中，使两种完全不同的应用程序建立起一条动态数据链路。当原始数据变化时，可以自动更新链接的数据。Visual Basic提供了动态数据交换的编程技术，可以在应用程序中与其他Windows应用程序建立动态数据交换，在不同的应用程序之间进行通信。2.外文原文Personnel Manageme

18、ystem.choice of development toolsNow, the market can buy a lot of application development products, popular, and dozens. Currently the mo st popular in our market, the most used, most advanced development tools can be used as enterprise-level products:Microsofts Visual BasicMicrosofts Visual CBorlan

However, the language of the flexibility and convenience tools are inextricably linked, and only a convenient tool, but did not support the language of flexibility, many specialized processing actions will need to spend s

If you are not satisfied with the effect of the interface, but also return to the program changes. Sometimes, this program

28、ming - Compiler - Change the operation may be repeated several times, greatly affected the efficiency of software development. Visual Basic provides a visual design tool, the complexity of the Windows interface design package together, developers do not have a lot of interface design and write code.

29、Just press the screen layout design, using system tools to draw on the screen various parts, that is, graphical objects, and set the properties of these graphical objects. Visual Basic code automatically generated interface design, programmers need only write the part to achieve functionality of the

30、 program code, which can greatly improve the efficiency of program design.Object-oriented programmingVisual Basic 4.0 support for future object-oriented programming, but it is the general object-oriented programming language (C + +) are not identical. In general object-oriented programming language,

31、 object code and data from the composition of an abstract concept; and Visual Basic is the application of object-oriented programming methodology (OOP), the programs and data encapsulated as an object and should be given for each object the attributes of the object as something real. In the design o

Each object is displayed graphically in the interface are visible. Structured programming languageVisual Basic is based

33、 on the BASIC language developed, high-level programming language with sentence structure, similar to the logic of natural language and human thinking. Visual Basic statements easy to understand, its editor supports color code, can automatically check for syntax errors, but also has powerful and fle

EXE), from the Visual Basic environment, directly in the Windows environments.Event-driven programming mechanismVisual Basic object through the event to perform the

36、 operation. An object may have multiple events, each event are available through a program to respond. For example, the command button is an object, when the user clicks the button, will generate a click (CLICK) event, but in the production of the event will execute a program used to implement the s

These processes are aimed at different objects, an event triggered by the user to drive the completion of a particular function or procedure called by the generic event-d
