Student management system design and implementation
文章来源:www.biyezuopin.cc   发布者:学生毕业作品网站  

As information technology advances, various management systems have emerged to change the daily lives of the more coherent, to the extent possible, the use of network resources can be significantly reasonable reduction of manual management inconvenience and waste of time.
Accelerating the modernization of the 21st century, the continuous improvement of the scientific and cultural levels, the rapid growth of the number of students will inevitably increase the pressure information management students, the inefficient manual retrieval completely incompatible with the community\'s needs. The Student Information Management System an information management one kind within system, currently information technique continuously of development, the network technique has already been applied in us extensively nearby of every trade, there is the network technical development, each high schools all make use of a calculator to manage to do to learn, the school is operated by handicraft before of the whole tedious affairs all got fast and solve high-efficiencily, especially student result management the system had in the school very big function, all can be more convenient, fast for the student and the teacher coming saying and understand accurately with management everyone noodles information.
AbstractIt is a very heavy and baldness job of managing a bulky database by manpower. The disadvantage, such as great capacity of work, low efficiency and long period, exist in data inputting, demanding and modification. So the computer management system will bring us a quite change.. Because there are so many students in the school, the data of students' information is huge, it makes the management of the information become a complicated and tedious work. This system aims at the school, passing by practically of demand analysis, adopt mighty VB6.0 to develop the student information management system. The whole system design process follow the principle of simple operation, beautiful and vivid interface and practical request. The student information management system including the function of system management, basic information management, study management, prize and punishment management , print statement and so on. Through the proof of using, the student information management system which this text designed can satisfy the school to manage the demand of the aspect to students' information. The thesis introduced the background of development, the functions demanded and the process of design. The thesis mainly explained the point of the system design, the thought of design, the difficult technique and the solutions. The student managed the creation of the system to reduce the inconvenience on the manpower consumedly, let the whole student the data management is more science reasonable. The place that this system has most the special features is the backstage database to unify the management to student's information. That system mainly is divided into the system management, student profession management, student file management, school fees management, course management, result management and print the statement. The interface of the system is to make use of the vb software creation of, above few molds pieces are all make use of the vb to control a the piece binds to settle of method to carry out the conjunction toward the backstage database, the backstage database probably is divided into following few formses:Professional information form, the charges category form, student the job form, student the information form, political feature form of student, the customer logs on the form The system used Client/Server structure design, the system is in the data from one server and a number of Taiwan formed LAN workstations. Users can check the competence of different systems in different users submit personal data, background database you can quickly given the mandate to see to the content.
Marks management is a important work of school,the original manual management have many insufficiencies,the reasons that,students' population are multitudinous in school,and each student's information are too complex,thus the work load are extremely big,the statistics and the inquiry have been inconvenient. Therefore,how to solve these insufficiencies,let the marks management to be more convenient and quickly,have a higher efficiency, and become a key question.
More and more are also urgent along with school automationthe marks management when science and technology rapid development,therefore is essential to develop the software system of marks register to assist the school teaching management.So that can improve the marks management,enhance the efficiency of management.
Systems Analysis and Design
Systems
Working under control of a stored program, a computer processes data into information. Think about that definition for a minute. Any given computer application involves at least three components: hardware, software, and data. Merely writing a program isn’t enough, because the program is but one component is in a system.
A system is a group of components that work together to accomplish an objective. For example, consider a payroll system. Its objective is paying employees. What components are involved? Each day, employees record their hours worked on time cards. At the end of each week, the time cards are collected and delivered to the computer center, where they are read into a payroll program. As it runs, the program accesses data files. Finally, the paychecks are printed and distributed. For the system to work, people, procedures, input and output media, files, hardware, and software must be carefully coordinated. Note that the program is but one component in a system.
Systems Analysis
Computer-based systems are developed because people need information. Those people, called users, generally know what is required, but may lack the expertise to obtain it. Technical professionals, such as programmers, have the expertise, but may lack training in the user’s field. To complicate matters, users and programmers often seem to speak different languages, leading to communication problems. A systems analyst is a professional who translates user needs into technical terms, thus serving as a bridge between users and technical professionals.
Like an engineer or an architect, a systems analyst solves problems by combining solid technical skills with insight, imagination, and a touch of art. Generally, the analyst follows a well-defined, methodical process that includes at least the following steps:
Problem definition
1 .Analysis
2. Design
3. Implementation
4. Maintenance
At the end of each step, results are documented and shared with both the user and the programmers. The idea is to catch and correct errors and misunderstandings as early as possible. Perhaps the best way to illustrate the process is through example.
Problem Definition
The first step in the systems analysis and design process is problem definition. The analyst’s objective is determining what the user needs. Note that, as the process begins, the user possesses the critical information, and the analyst must listen and learn. Few users are technical experts. Most see the computer as a “magic box,” and are not concerned with how it works. At this stage, the analyst has no business even thinking about programs, files, and computer hardware, but must communicate with the user on his or her own terms.
The idea is to ensure that both the user and the analyst are thinking about the same thing. Thus, a clear, written statement expressing the analyst’s understanding of the problem is essential. The user should review and correct this written statement. The time to catch misunderstandings and oversights is now, before time, money, and effort are wasted.
Often, following a preliminary problem definition, the analyst performs a feasibility study. The study, a brief capsule version of the entire systems analysis and design process, attempts to answer three questions:
1.      Can the problem be solved?
2.      Can it be solved in the user’s environment?
3.      Can it be solved at a reasonable cost?
If the answer to any one of these questions is no, the system should not be developed. Given a good problem definition and a positive feasibility study, the analyst can turn to planning and developing a problem solution.
Analysis
As analysis begins, the analyst understands the problem. The next step is determining what must be done to solve it. The user knows what must be done; during analysis, this knowledge is extracted and formally documented. Most users think in terms of the functions to be performed and the data elements to be manipulated. The objective is to identify and link these key functions and data elements, yielding a logical system design.
Start with the system’s basic functions. The key is keeping track of the stock-on-hand for each product in inventory. Inventory changes because customers purchase, exchange, and return products, so the system will have to process customer transactions. The store’s owner wants to selectively look at the inventory level for any product in short supply and, if appropriate, order replacement stock, so the system must be able to communicate with management. Finally, following management authorization, the system should generate a reorder ready to send to a supplier.
Design
As we enter the design stage, we know what the system must do, and thus can begin thinking about how to do it. The objective is to develop a strategy for solving the problem. At this stage, we are not interested in writing code or in defining precise data structures; instead, we want to identify, at a black box level, necessary programs, files, procedures, and other components.
The data flow diagram defines the system’s necessary functions; how might they be implemented? One possibility is writing one program for each process. Another is combining two or more processes in a single program; there are dozens of alternative solutions. Let’s focus on one option and document it.
Implementation
Once the system’s major components have been identified, we can begin to develop them. Our system includes two programs, several pieces of equipment, and a number of data structures. During implementation, each program is planned and written using the techniques described in Chapter 7. Files are created, and their contents checked. New hardware is purchased, installed, and tested. Additionally, operating procedures are written and evaluated. Once all the component parts are ready, the system is tested. Assuming the user is satisfied, the finished system is released.
Summary
A system is a collection of hardware, software, data, and procedural components that work together to accomplish an objective. A program is but one component in a system.
System are planned and designed by system analysts who generally follow a well-defined, methodical process. The first step in the process is problem definition, when the analyst attempts to discover exactly what the user needs. Often, following a preliminary problem definition, a feasibility study is conducted to determine if the problem can be solved.
Given a clear problem definition, analysis begins. During this stage, the analyst develops a logical model of the system. Key functions are linked through a data flow diagram. Using the diagram as a tool, the data flows are traced, and the system’s data elements are identified and recorded in a data dictionary. After the logical system is reviewed with the user, design begins.
During design, the analyst develops a model of the physical system. A system flowchart can be used to map the system, defining each physical component as a symbol. A good systems analyst considers a number of alternative solutions to the problem before settling on one. Implementation follows design. Programs are planned and written; hardware is ordered and installed; procedures are written; files and databases are initialized; and, finally, the pieces are assembled and tested. Following release of the system, maintenance begins
