1、毕业设计（论文）报告纸英文文献： Personnel management system development and design By Dustin MarxSummary 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

2、, enterprises 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 c

3、omputer to 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 in

4、tegration 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. Cur

5、rently the 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 implement

6、ation of process 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 a

7、nd 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 several times the effort to deal with, so the efficiency of the original advertisedloss of a role in improving the advanta

8、ge; the contrary, 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

9、ideal choice. 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, each product has its own characteristics and scope, therefore, the choice of database should consider th

10、e 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 develop t

11、he 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 mechanism,

12、 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 environme

13、nt, 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 ac

14、tual 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 de

15、velopment. 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 obje

16、cts, 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 Basic

17、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 object-o

18、riented 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, Vi

19、sual Basic automatically generates the object 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, similar to the logic o

20、f 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 the same time, dec

21、omposition 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, you can compil

22、e 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 respond. For exa

23、mple, 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, without creating a

24、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 process to perf

25、orm 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 format, and prov

26、ides 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 open data connectio

27、n, 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 pro

28、vides a simple object-oriented database instructions and multi-user database access locking mechanism and network programming SQL databasestechnology for stand-alone databases running on the SQL network interface to a distributed environment, fast and effective implementation of client / server (cli

29、ent / server) programs. Dynamic Data Exchange (DDE) Using Dynamic Data Exchange (Dynamic Data Exchange) technology, an application can dynamically link the data to another application, so that two completely different applications, establish a dynamic data link. When the original data changes, you c

30、an automatically update the linked data. Visual Basic provides the programming dynamic data exchange technology, the application program with other Windows applications to create dynamic data exchange between different applications to communicate. Object Linking and Embedding (OLE) Object Linking an

31、d Embedding (OLE) to each application as an object (object), to link different objects (link) up, and then embedded (embed) an application, which can be a sound, image, image, animation, text and other information collection style files.OLE technology is Microsofts strategic corporate object technol

32、ogy, which the multiple applications into one, as each application for an object linking and embedding, is an application integration technology. Using OLE technology, you can easily build composite documents (compound document), this document from a number of different application objects, each obj

33、ect in the document and linked to the original application, and perform with the original application the same operation. Dynamic link library (DLL) Visual Basic is an advanced programming language, do not have low-level language functions, the operation of the access to the machine hardware is not

34、easy to implement. But it could be dynamic link library technology will C / C + + or assembly language programs to Visual Basic applications, you can call the same function as the internal call functions written in other languages. In addition, the dynamic link library, you can call the Windows appl

35、ication program interface (API) function has the function to achieve SDK. systems research and feasibility analysis Research Before the formal development of management information system is necessary for research, the need for mainly the following aspects. (1) to the users request to conduct a feas

36、ibility analysis of the survey results confirm the feasibility of system development. (2) The staff of the new system not all systems researchers, some people process data for its function and no clear understanding of the method. They only work according to their business needs requests, system dev

37、elopers to conduct a detailed survey and analysis to confirm the users requirements can be achieved through the existing computer technology to ensure the development of management information system functions and user submitted required match. (3) the existing business system may be a manual system

38、, it could be used and the computer system, no matter the circumstances, the current system should be investigated in detail the specific circumstances of information processing, functional structure within the system in order to design a reasonable, good new system logic model for the design of the

39、 new system to lay the foundation to ensure the quality of the entire system development. In short, the current system is necessary to conduct a detailed investigation, a clear user needs, to ensure the development of new system functions consistent with the users requirements and avoid a lot of man

40、power, material and financial resources, the development of the new system is the failure of the tragedy. Overview of Feasibility Study Feasibility analysis is the users requirements and system on the basis of research conducted on the development of new systems of social, technical, economic, manag

41、ement, analysis and development of new systems come feasible, not feasible, need to modify , additional investment, the suspension of development, step by step and other programs and conclusions, and finally complete the feasibility analysis. Feasibility analysis of the general can be defined as: a

42、feasibility analysis early in the construction of a project study and appraisal of the proposed project to conduct a comprehensive and integrated technical and economic capacity of the investigation to determine whether it is feasible. (1) the feasibility study stage of the work include the followin

43、g: Objective analysis of whether the new system status and business development needs. social feasibility analysis: Social feasibility analysis mainly refers to the management information system development is consistent with national law, bad policy, whether we can achieve a good social system and

44、docking. technical feasibility analysis: Technical feasibility analysis is based on the new system aims to measure whether they have the required technology, including the number and level of system developers, hardware, software and other application technologies. economic feasibility analysis Econ

45、omic feasibility analysis is mainly on the development of capital invested in new systems and systems put into use to compare the economic benefits to confirm whether the new system will bring some economic benefits companies. management feasibility analysis: Management feasibility analysis is to an

46、alyze existing enterprise management system and whether the business leaders of modern management awareness and management.Technical feasibility analysis Technical feasibility analysis includes four aspects: the current technology can support the new systems developed; the new system the number and

47、level of developers, namely, human resources; hardware and software resources. (1) Technical Support: First, the target under the new system, considering the current technology can support the new systems developed. Technology must be discussed here has been widely used, not to be studied or are stu
