1、英文文献： Personnel management system development and design By Dustin Marx Summary With the rapid development of computer technology, computer applications in the popularity of business management, personnel management of enterprises using computers is imperative. For medium-sized enterprises, enterpri
2、ses and efficient use of computer support to complete the daily affairs of labor and personnel management is to adapt to the modern enterprise system, encourage enterprises to labor and personnel management to scientific, standardized, a necessary condition； incomparable advantage of the computer to
3、 retrieve managementrapid, easy to find, high reliability, large memory capacity, security and good, long life and low cost. These advantages can greatly improve the efficiency of personnel management, but also corporate scientific and standardized management, an important condition for integration
4、with the world. Different companies have different human resources management system, which determines the different companies need different personnel management system. choice of development tools Now, the market can buy a lot of application development products, popular, and dozens. Currently the
5、 most popular in our market, the most used, most advanced development tools can be used as enterprise-level products: Microsofts Visual Basic Microsofts Visual C Borlands Delphi Java, etc. In the current market, many application development tools for these, some stressed that the implementation of p
6、rocess flexibility and efficiency of language； and some emphasis on the visual application development tools to bring convenience and efficiency high, each with its own advantages and characteristics, but also to meet the needs of different users. However, the language of the flexibility and conveni
7、ence 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 several times the effort to deal with, so the efficiency of the original advertisedloss of a role in improving the advantage； the co
8、ntrary, if the language only emphasizes the flexibility of process continued, but no convenient tool for co-ordination will make some very simple interface, even if the deal moves, programmers will be a serious waste of valuable time. As the database system development, Visual Basic is an ideal choi
9、ce. MIS database is an important enabling technology in the MIS development process, how to choose the database management is an important issue, at present, the database more products, 共 13 页 第 1 页 each product has its own characteristics and scope, therefore, the choice of database should consider
10、 the characteristics of database applications and application, the systems database language used Visual Basic language, the development tool has many advantages: Visual Basic is a visual, object-oriented and event-driven article by the way of structured high-level programming, can be used to develo
11、p the type of Windows environment applications. It is easy to learn, efficient, and powerful, with professional development tools, Windows SDK comparable to, and application developers do not have the C / C + + Programming. In the Visual Basic environment, the use of event-driven programming mechani
12、sm, novel-to-use visual design tools, the use of Windows internal application program interface (API) functions, and dynamic-link library (DLL), Dynamic Data Exchange (DDE), Object Linking and Embedding (OLE), Open Data Access (ODBC) technology, can efficiently and quickly developed a Windows enviro
13、nment, powerful, rich graphical user interface application software system. In general, Visual Basic has the following characteristics: Visual Programming: Traditional programming language design program, are designed by writing code to the user interface, the interface design process do not see the
14、 actual display, run the program to be compiled can be observed. If you are not satisfied with the effect of the interface, but also return to the program changes. Sometimes, this programming - Compiler - Change the operation may be repeated several times, greatly affected the efficiency of software
15、 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.Just press the screen layout design, using system tools to draw on the screen various parts, that is, graphical o
16、bjects, 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 program code, which can greatly improve the efficiency of program design. Object-oriented programming Visual Bas
17、ic 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, object code and data from the composition of an abstract concept； and Visual Basic is the application of objec
18、t-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 of objects, without writing to establish and describe each object code, but with the tool to draw the interface,
19、 Visual Basic automatically generates the object 共 13 页 第 2 页 code and package it. Each object is displayed graphically in the interface are visible. Structured programming language Visual Basic is based on the BASIC language developed, high-level programming language with sentence structure, simila
20、r 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 flexible to use debugger and compiler. Visual Basic is an interpreted language, enter the code at th
21、e same time, decomposition of high-level language interpretation system will be translated into machine instructions the computer can recognize and judge each statement syntax error. Visual Basic procedures in the design process, you can always run the program, and in the whole process a good design
22、, you can compile an executable file (. EXE), from the Visual Basic environment, directly in the Windows environments. Event-driven programming mechanism Visual Basic object through the event to perform the operation. An object may have multiple events, each event are available through a program to
23、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 specified operation. In the design of large-scale applications using Visual Basic software, wit
24、hout creating a clear beginning and end of the procedure, but the preparation of a number of small subroutines that process. 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-driven
25、 process to perform the specified operation, so that programmers can easily and improve efficiency. Access to the database Visual Basic has a powerful database management features, the use of data control and database management window, you can directly create or deal with Microsoft Access database
26、format, and provides powerful data storage and retrieval capabilities. At the same time, Visual Basic can also directly edit, and access to other external databases, such as DBASE, FoxPro, Paradox, etc. These database format can be edited and processed using Visual Basic. Visual Basic provides an op
27、en data connection, the ODBC functions, can be established through direct access or use the connection and operation of large-scale network database backend such as SQL Server, Oracle and so on. In the application, you can use structured query language SQL data standards, direct access to the server database and provides a simple object-oriented database instructions and multi-user database access locking mechanism and network programming SQL
