In the view layer, the role of the students ca

23、n get the information of each course or take an examination. As a teacher, who can examine the examination papers or set the paper, and so on. Dean can modify and delete the paper from all teachers or view the message, and so on. After they send the request, the control layer would process the reque

24、st and take the information from the Model layer to the view layer.图2.1.1 MVC model图2.1.2 Scandalous deployment figure2.2 B/S structure and XMLWe use open source, choose B/S structure and XMLopen sourceIn open source, we used the OO database eXist. Choosing eXist because it can be a very good in XML

25、 documents operation and also provides a better user interface. On the other hand, open source has the following four distinct advantage :1. Open source technology is a very low cost and has very low or even zero cost in exit barriers advantage.2. Open source can enhance interoperability.3.In resear

26、ch and development, it can use more resources.4. Open source more secure and very little virus. Because our source code are shared on the Internet, so no secret.B/S architectureIn this system ,we use B/S architecture .Because B/S structure can be combined with a variety of Script language and Active

27、 technology in browser .It can achieve power function before using special and complex softwares , which can save a lot of cost in development. B / S based on the WAN, which is for different user groups and geographic dispersion . However ,C/S structure cannt do that. We know that B / S based on the

28、 browser , so it can be cross-platform by WEB services or other public can identify the description language and using more flexible.Not only been used in Window platform , but B/S structure can be used in Unix/Linux platform .In addition, in the performance of the system , B/S advantage is that any

29、 time, any place, any system, so long as can use the browser on the Internet, you can use the B/S system of terminal . Besides, most C/S structure of software are directly connected to the database through ODBC ,which would lead to poor safety and limited number of users .Because each user will be c

30、onnected to the database to maintain a ODBC connection, so resources have been occupied all the time and user expanded by great limits. On the contrary, all users are using a JDBC connection pool to connect to the database in the B/S structure. So, the user does not maintain a connection to the data

31、base and subscribers basically is limitless.Using XML to store the news informationWe choose XML as the tool to store data because of its advantages. Compared with other data formats , a major advantage of XML is that it is very similar to the object data structure. Since the most of current program

32、 design and development is object-oriented, so using XML to expression data that can enable data processing and dissemination has become very convenient. Firstly, XML format is versatility, convenient, and high efficiency, which can be used on any platform. Secondly, XML has the advantage of keeping

33、 the user interface and the structure in the separation between the data. An XML document ,which storing data, can be analyzed by program. Then, the data be extracted from the inside to be used or stored in database. These data can be used or called in a variety of occasions .In addition, we know th

34、at XML is extensible markup language, so, users are free to set their own markup language. By storing data in XML, you can largely reduce the database access .The last one is that XML broke all kinds of fortress on networks, which lead to value of the data can flow and exchange between them, and to

35、achieve the business purposes of sharing information.三、Detailed design 3.1 General framework design(总体架构设计) 3.1.1The General principles of design for the systema. Simplification(简单化) The system should be easy to use when meet the requirement and reach the goal of expectation.b. Flexibility(灵活性) The

36、system should adapt to the changes of the Environment.c. reliability(可靠性) The system should have a high reliability.3.2 project pictures including the packages and classes.Picture 3.2.1 the java code of eXist datebasePicture 3.2.2 the java code of roles Picture 3.2.3 all the files of the admin Pictu

In this project. We use the object-oriented database eXist to store and manage the

41、 xml files. eXist is an open source database management system entirely built on XML technology, also called a native XML database. Unlike most relational database management systems, eXist uses XQuery, which is a W3C Recommendation, to manipulate its data.Picture 3.4.1 The flow of OODB-Exist proces

44、 been finished normally or not by the black-box testing method. In testing, the program as a can not open the black box, while not considering the internal structure and internal characteristics completely, testers test the program by the programming interfaces. Black box testing only check whether

45、the programs functions can use normally according to the product requirement specification and the program can print a right result when the users have a appropriate input or not, and keep the integrity of external information (such as database or documents).4.1.2 Test design techniquesTypical black

46、-box test design techniques include: Decision table testing. All-pairs testing. State transition tables. Equivalence partitioning. Boundary value analysis. 4.1.3 What is black-box testing.Black-box testing is mainly to found the following categories errors:1. Whether there be incorrect or omissions

47、functions?2. In the interfaces, can accept input correctly or Can output the correct result?3. Whether there is a data structure errors or external information (for example data files) errors?4. Whether the performance can meet the requirements?5. Whether have initialization or terminate mistake? 4.

53、c purpose of To test extreme data ,and it is the minimum entity executed. Here is a test case for login function model: 4.3 Test extreme dataBoundary value analysis (BVA) is a black box testing method used to test the boundary values of input or output .1. Select the boundary value test principle1)

54、if the input conditions stipulated the maximum number of maximal number is used, the minimum number, the number of small a than the smallest number, than the largest number freshman number as test data.2) if the input conditions stipulated the value of scope, it should be taken just reached this ran

55、ge boundaries values and just beyond this boundary value as a test input data.3) if the program was used in an internal data structure, should choose the internal data structures of the boundary value as test cases.4) if the program specification given input fields or output domain is ordered set, s

56、hould be selected set the first element and the last element as test cases.5) analysis program specification, and find out the other possible boundary conditions.2. The common boundary value1) screen cursor in the upper left, most lower position.2) array element of the first and the last one.3) The first line and the last line of statements.4) The 0 times, the first time, reciprocal
