CHAPTER ONESOFTWARE REQUIREMENT1 SPECIFICATIONI

I11 Introduction

111 Purpose of Project t

There are many Web sites that provide interactive

tutorials for students such as CBT GTSS and etc There is no evaluation of students understanding and learning

in these web sites In order to solve this problem the

idea of creating evaluation tool was proposed in Fall 2000iIas a master project called Web-based Interactive

Self-Evaluation System I

The goal of this master project is to promote andI

facilitate the use of new Web-based and Java-basedI

technologies in the development pf self-evaluation systemIfor computer science in particular analysis of sorting

Ialgorithms This project is built as part of the GTSS system (see figure 11) WISE will promote Web-based interactive exercises by providing educators with thetools to create interactive exercise materials Students

are able to evaluate their understanding though exercises

1

II

112 Scope of Project

WISE project will provide tools to create exercises 1and to evaluate students performance Evaluation topics

are limited to sorting algorithms that include Selection Sort Insertion sort Bubble Sort Quick Sort and Heap

ISort These are important topicsiin computer scienceStudents who understand sorting algorithms very well can

Idevelop efficiently software i

Ithe final product the complete tutorial system The

complete WISE project consists of two main parts GTSS tutorial and WISE application server (see figure 12)

Project Product with Deployment DiagramrFigure 12 Project Overview i

I1Sorting algorithm Tutorials These tutorials

iinclude the concept of each sorting algorithms and

analysis of sorting algorithms in term of Big Oh notationi2Interactive self-evaluation exercise system This

system includes interactive exercise creator tool

question management tool and score analysis These

easy-to-use tools will help instructors create interactive I

exercises in the area of sortingialgorithms Creating someI

of the exercises may require the programming to set rules

system The system will evaluate 1 the student scores withI

the passing scores set by the instructors If studentspass they can start the next chapter otherwise they

irepeat the current chapter is required

122 Functionality of Project

In WISE system all functions are categorized by

level of users which include student level instructorlevel and administrator level Figure 14 shows a Use Case

diagram which describes the functionalities provided byWISE system i

1221 Instructor Level The instructor is able toi

create edit and delete sorting algorithm questions by

using tools such as EZ question creator to create

questions and Question Manager to edit and deletequestions Question Manager engine handles all activitiesdescribed above The instructor can also access students

Irecord to view their score and evaluate studentsunderstanding

1222 Student Level After the student finished

their tutorial applets The Question Manager engine will

generate a set of questions Most questions automaticallygenerate answers Then they are shuffled them by theQuestion Manager engine The Answer Manager engine is

Iresponsible for counting score and recording it in the

student database If the student passes the exam the

student can start the next tutorial otherwise the Answer

Manager engine locks the current chapter until the studentpasses the exam

1223 Administrator Level) System administrator or SA has the major task to maintain all the tables in the

IWISE database and overall system) SA is able to create

instructor and student account Students and instructorsIIcannot delete their account unless the SA does The User

Manager engine will handle these tasks on the backgroundUser manager engine also checks user logins to ensure thatonly registered student access the system

SA has also to maintain the knowledge base With the

knowledge base engine SA can manage the knowledge base

that is used for creating new questions by the

instructors

123 System Analysis and Requirements

The WISE system consists of1 several components in sorder to work properly a)Java Server Pages (JSP) b)Java

Database Connectivity driver (JDBC) and c)MySQL database engine In this section each component will be described briefly In WISE system all information will be stored in MySQL databases The front-end applications will be

written by JSP All applications I will use JDBC to connect

to databases I(a) Java Server Pages consists of powerful JAVA

programming language integrated with the

server-side script language based on extra markupIlanguage or XML These itake JSP easy for dynamiciWeb programming Furthermore JSP uses graphicsfrom HTML As a result JSP applications run faster Compared to the(other server side language such as Active Server Pages (ASP) PERLor PHP JSP has the major advantages of real

object-oriented run faster and highly reusableIJSP is a language of choice for creating dynamicI

Web-based interaction

Since WISE contains many interactive forms to get data in or to display result out it is a igood idea to use JSP imWISE system Integration

8

of GTSS and WISE systemwill not slow the systemIdown because WISE system will optimize GTSSi

performance I

There are many advantages to use JSP in WISEIsystem

mdash WISE system is objett-oriented which is thesame as GTSS WISE can be very modular and

Ireadily adapted to new usesI

mdash As a teaching interactive material tool aI

well-written JSP program allows the

instructor to focus1attention precisely ont

the point at hand 1I

- With build-in templates it will be easy for

instructors of the computer sciences to[develop additional interactive exercises with

minimal requirement1 for programmingi

(b) Java Database Connectivity defines a structuredinterface to Standard Query Language (SQL)

Idatabase The JDBC API provides Java developers

Iwith consistent approach to accessing SQL

I I databases that is comparable to existing database I development techniques I The JDBC API includes

Iclasses for common SQL database constructs such

ias database connections SQL statements and

9

result sets JDBC database drivers can either be I Iwritten entirely in Java or they can be

implemented using nativg methods to bridge Java1

application to existingdatabase access

librariesI

(c) Databases are becoming a big part ofiapplications and one of the most popular products is MySQL fromMySQLcom MySQL is a

free product under General Public License MySQL

has many advantages over the other databaseIengine products such as 1 reliability speed andI

capacity

MySQL can run on ariy platforms such asIwindows 98 or NT UNIXLINUX and etc Using

IMySQL is also easy to use with simple SQLicommands

124 Hardware and Software RequirementIn order to successful develop WISE system the

ihardware and software are a major concern Minimumrequirements are specified here both a) development and b)

implementphasesI

(a) Development Phase is the phase that involvesIdesign coding and debugging of this project The following hardware and software specification are

1 Algorithm Analysis (Review)

X

An algorithm is a clearly specified set of instructions the computer will follow to slove a problem Once an algorithm is given for a problem and detemined to be correct an inportant next step is to determine the amount of resources such as time and space the algorithm will require This process is known as algorithm analysis

Algorithm analysis is mostly measuring of the computational time to run algorithm Because the behavior of an algorithm may be different for each possible set of data there needs to be a means for summarizing that behavior in simple easily understood formulas One way to derive these formulas is the big 0 notation Big O notation also called an efficiency indicator is used to describe the growth rate of a function The big O notation represents the running time needed to solve the computational steps

CHAPTER TWO

DESIGN

After defining all software specification the next

step in software development life cycle isdesign Design is a creative process Software design guality is depended on understandability verification and adaptability To achieve this goal Unified Modeling Language (UML) is used

for software analysis and design It simplifies thecomplex process of software design making a blueprint for construction Use Case is one example of UML that

define functionality of software in the last chapter In this chapter other UML diagrams such as class diagram

will be used in the following section From the last

chapter (Figure 12) project product goals are to create sorting algorithm tutorials and complete interactive tutorial system in the GTSS system Therefore these twoproduct goals will be discussed

The GTSS Project is an on-going project in the

department of computer science mathematics physics and

chemistry at CSUSB We used the GTSS tools and built newones to implement WISE

36

21 Architecture Design

221 Sorting Algorithm Tutorials Design

The GTSS structure consists of 3 layers core

objects engine objects and application objects [1] For Sorting Algorithm GTSS applets WISE still use the same

structure Furthermore new applets add more classes to the engine objects and application objects to make new

sorting algorithm applets run correctly Figure 21 showsstructure of GTSS

From Figure 21 Core Objects are used for creatingprimitive graphics such as frames text canvases

buttons menus etc The Engine Objects are build on top

37

of the core objects and though inheritance and

polymorphism this engine supports the generation of

windows and graphics for the specified subject TheApplication Objects are a set of objects that is used togenerate windows and graphics for a specific topic in a subj ect

2111 Core Objects There are seven classes in the

Core Objects that are used to build new sorting algorithm

applet They are SGApplet SGFrame SGControlPanelSGMenu SplashPanel HsplitPanel and Vspiltpanel (SeeTable 21)

Table 21 Core Objects

Class Name FunctionSGApplet This is the superclass of all appletSGFrame Defines a FrameSGControlPanel Specifies button on panelSGMenu Specifies menus on menus barSplashPanel A panel used for demonstrationHspiltPanel Defines a two horizontally split

panelsVspiltPanel Defines a two vertically split panels

2112 Computer Science Engine Objects The Computer

Science Engines that are used in creating new sorting

algorithm tutorials contain six classes ScatterPanel

SortPanel Scatterlnterface Pseudocode Sortlnterface

and Sortnode (See Table 22)

Class Name FunctionScatterPanel Panel that displays the scatter

graphScatterlnterface Class interface to ScatterPanelSortPanel Defines the base panel for sort

walkthroughsPseudocode Defines the base panel to display

algorithmSortlnterface Class interface for SortPanel amp

PseudocodeSortnode Defines graphical boxes for

sorting animation

The Computer Science Engine Objects are built using Core Objects Computer Science Objects define basic graphics about animations such as sorting pseudocode and rectangular boxes for sorting animation It rules also contains how to animate them such as swapping the boxes orhighlighting on lines in the pseudocode

2113 Application Objects The current GTSSstructure supports four applications Computer Science Physics Mathematics and Statistics We will continue ourdiscussion on computer science applets

39

The five new applets added to GTSS foe computer

science are the following(a) Selection Sort is a Selection Sort walkthrough-

of the steps by steps execution of thealgorithm

(b) Insertion Sort is an Insertion Sort walkthroughof the steps by steps execution of the

algorithm

(c) Quick Sort is a Quick Sort walkthrough of the

steps by steps execution of the algorithm(d) Heap Sort is a Heap Sort walkthrough of the

steps by steps execution of the algorithmIn Application Objects We define the rule how the

algorithms associate with the pseudocode and rectangularI1 boxes by adding actionlistener Every time the user clicks

on forward button We define two more classes for every sorting applet to handle this situation In insertion sort for example they are Iswalkjava andISControljava These two classes will tell the appletwhat animation should it do This method is applied to

every new sorting algorithm in GTSS Table 23 shows new

Application Objects built for new sorting tutorial

algorithms

Class name FunctionIswalk and ISControl Integrate all components objects

and Control Insertion sort animation applet

SSWalk and SSControl Integrate all components objects and Control Selection Sort animation applet

Hswalk and HSControl Integrate all components objects and Control Heap sort animation applet

Qswalk and QSControl Integrate all components objects and Control Quick sort animation applet

Using GTSS to create new applet is quite easy sincethere are preprogrammed classes available for instructors

to create a new applet But one major drawback is thatinstructors must know how to program in Java Using Javabean visual tools that help to eliminate the need of

programming in Java because Java bean allows the user tocreate applet in a visual programming environment cansolve this problem

Figure 22-25 shows the class diagrams of Insertion

sort Selection Sort Quick Sort and Heap Sort All fivesorting algorithm applets have the same class diagram

structures The class diagram shows all the Objects usednow integrated into one big picture showing the

41

relationships of all objects This class diagram alsoshows the detail of functions and variables for each class

that binds together to run this applet This is also the

standard pattern of all future animation applets unless

this rule will be customized by instructors to fit future0

applet requirements

212 Interactive Self-Evaluation System Design

As an extension project for GTSS WISE is added WISE

system design is based on object-oriented design WISE

architecture consists of two object layers core andapplication

The Core Object in WISE system consists of both mainclasses that connect to database and file and utility

classes that deploys superclasses to perform tasks that

help WISE run application object faster and with no error

Table 24 shows all classes in Core Objects

Table 24 Core Classes

Class Name Class FunctionConnectsql A super class for all objects To

define databaseConnectfile A Super class for file objectsQueryBean Control query statementInsDelUpdBean Control insert delete or update in

databaseFilebean Worked with connectfile contain detail

information to save to or read from identified filename

Shuffle Shuffle all choices by randomCreateChoice Base from correct answer system will

create almost the other four right answers before shuffle

RandomNumber Random number by specified rangesScorebean Control and manage students scoreReadFileBean Reading information from file and send

to display at screen

47

Application objects are classes that present all functionality provided by WISE system Functionalities of WISE system was explained in chapter one using casediagram The main functionalities that show in the

application objects can divided into five main groups

question manager user manager table of content manager test taking and miscellaneous The following tables show all Application Objects categorized by function

Figure 27 shows the WISE class diagram The

connectsql class and connectfile are superclasses of all

classes in WISE system Connectsql has the databaseconnection information Connectfile also has filenameconnection information which is useful when the systemloads the students exercise file

After the student logs on to WISE system the student

can browse student menu which includes GTSS test taking show score and personal information Test takingassociates with Qmanager which manages and creates tests for the student Userupdate UI has dependency withuserinfoBean Instructor can also browse the main menuwhich includes table of content manager score manager question manager and knowledge base manager Table ofcontent manager has direct association with TOCadd

TOCupdate and TOCdel Question manager also associates

with addQuesitonG and EZ question manager These two classes create new question to WISE system Knowledge base manager associates with kbase_creator kbase delete and

50

kbase_update Knowledge base system is very important for questions that use Java program to create question

Question manager will use knowledge base information to

create test Every class associates with connectsql to

access the database to update insert delete or query

CHAPTER THREE

TESTING

Testing or software validation is the testing processto ensure that the program as implemented meets the

expectation of the user [3] The purpose of system

validation is to have assurance about the software quality

and functionalities This guarantees system performance and reliability also

31 The Testing Process

There are three testing processes that are used intesting WISE system unit testing subsystem testing andsystem testing

Except for small computer programs it is unrealisticto attempt to test systems using only unit testing Largesystems are built out of many small subsystems which may themselves be built out of procedures WISE system wastested by all three testing methods

32 Unit Testing

Unit testing is the basic level of testing where

individual components are tested to ensure that they

operate correctly These individual components can beobject class program and etc The following test rules

95

are defined to check that each component meets

specification

(a) Verify the handling of all valid input data type(b) Verify the handling of error condition(c) Check normal and abnormal program termination

(d) Check all buttons work as expected

Unit test offers the most effective way to detect

problems when comparing with the other testing methods On

the other hand this testing method cost more time and money to execute The later testing methods will show an

effective way to save time which will be discussed innext two sections The unit testing results of WISE system

are shown in Table 31

33 Subsystem Testing

Subsystem testing is the next step up in the testing

process where all related units form a subsystem to do a

certain task Thus the subsystem test process is useful

for detecting interface errors and specific functionsTable 32 shows subsystem test results in detail

CHAPTER FOUR

MAINTENANCE MANUAL

It is impossible to produce systems of any sizewhich do not need to be maintained System maintenance is

an important step to ensure that the system runs smoothly

and meets the customers expectation In WISE system

there are five major maintenance issues WISEs files and

directories WISE installation system migration anddatabase maintenance and program modification

41 Files and Directories

I have arranged related file and directories based onthe design in Chapter two There are seven main

directories see Tables 41-47 All directories are underusrlocaltomcatwebappswiseweb-infclasses

Table 41 Files in Main Directory

42 Software Installation

This section shows how to install WISE to in theLinux operating system I assume that JSP Tomcat serverand mySQL are already installed in Linux system Thefollowing steps are needed for system migration

1 Download wisetargz file that is available atgtssiascsusbedu website

2 Copy the file to usrlocaltomcatwebapps3 extract the file by using this linux command

tar -xzvf wisetargz

4 Edit file usrlocaltomcatconfserverxml by adding the following line in the context manager section ltContext path=wise

108

docBase=webappswise debug=0

reloadable=true gt ltContextgt

5 Restart JSP tomcat server

WISE

43 System Migration

system is designed to run across platforms butif system administrator plans to move from one platform to

another there is nothing to do with WISE system except a

few check on configuration

When system administrator plan to move system to

different platform for example from Linux to windows The

following steps are needed for system migration

1 Make back up of the WISE system which is located

2

at usrlocaltomcatwebappsWISE

Make another backup of WISE database which is

3 located at usrlocalmysqldataWISESystem Administrator must download install and

4 configure JSP and MySQL windows versionDownload and install JDBC driver from

5

httpmmmysqlsourceforgenet

Copy back all backup files in Nol to both JSP

and MySQL directories

109

44 Database MaintenanceThe MySQL database locate at usrlocalMySQL in

Linux platform In order to perform maintanance process

system administrator has to log on to MySQL server to do

maintanance job Administrator can grants user to maintain

database by give permission in user table and db table of

mysql database Mysql database is located atusrlocalmysqldatamysql In user table there are a

variety of permissions such as grant user to modify tableor grant user to shut down server Db table is a table

that limit user to access databases

Example To add a user you must first logon to theMySQL database as administrator and use the mysqldatabase To do this perform the following steps

1 Change to mysql installation directorycd usrlocalmysql

2 Ensure that the mysqld is up and running binmysqladmin -p ping

3 You will be prompted for your root password

After you have entered it correctly you be able

to access mysql database by typing in thefollowing

use mysql

110

4 To create new user use the following command

insert into user(hostuserpassword)values

(gtssiascsusbeduscottpassword(test))5 To add select privileges to scott administrator

uses the following command

insert into db(hostuserdbselect_priv)

values(gtssiascsusbeduscottWISEY)

45 Recompilation

Usually Most of sixty-five percents of maintenancetask apply to modifying a program after it has been

delivered and is in use These modifications may involvesimple changes to correct code errors more extensivechanges to correct design errors or rewrite code to meetnew requirements

JSP keeps all compiled java programs (filenameclass)in usrlocaltomcatwebappswiseweb-infclassesModified java program must recompile by using javacfilenamejava command at Linux prompt After compiledJava will create filenameclass which will be moved to

the directory mentioned above

Alternative way is to create jar file The jar is theway to group all compiled Java program together as one

111

file The advantage is portable and easy to manage To

create jar file system administrator must compile all

Java program to get dot class files The next step is to group those files together by using the following command

jar cvf wisejar class Then using mv wisejar usrlocaltomcatlib to move the dot jar to the place

that Java program can link to

CHAPTER FIVECONCLUSIONS AND FUTURE DIRECTIONS

51 Conclusion

WISE system shows another successful project in GTSS

project which includes complete sorting algorithmtutorials system and interactive self-evaluation exercisesystem With Java object-oriented design and MYSQL

database design WISE system delivers fast reliable and

highly portable Web-based exercise management system

By using this master project students can evaluate

their understanding of Analysis of sorting algorithmthrough on interactive online system Also instructors areable to create and manage questions to evaluate students

performance via WISE self-evaluation tools Tools for creating self-evaluation exercises include EZ questioncreator for creating question database and automaticexercises and knowledge base creator for creating newintelligent Java programs for creating automatic answer toprevent cheating

WISE can be accessed anywhere by any Web browserJava runtime environment software version 11 or later isrequired to access the system A user can download this

free software from Sun Website or automatically download

113

on Windows platform By using session tracking technology

the user activity information can be kept securely on WISEserver This ensures the user privacy

Moreover the experiences in implementing this

project consist of using various technologies Java JDBC

MySQL and Web server which provided valuable knowledgefor myself

52 Future DirectionsWISE system shows a new way in implementing

interactive self-evaluation system on the Web WISEsfeatures were declared earlier in Chapter One Using theseas the starting point WISE may have additional and

improved features521 Adaptive Test

By using artificial intelligence concept newadaptive test can be developed Adaptive test is an intelligent tests that respond with the users answerWhen the user answers a question correctly the nextquestion will be harder otherwise easier question will be

asked Test engine will calculate the score based on the

weighted of the correct answers

114

522 Graphic Score Analyzer

With the current score representation WISE systemstill shows an individual score This analyzer tool will include for all the registered users in WISE system

Graphic score analyzer will help students compare their

score with others With graphic color bar chart or pie

charts the students can measure their abilities

APPENDIX

GLOSSARY

116

Terminology DefinitionInsertion Sort Sort by repeatedly taking the next

item and inserting it into the final data structure in its proper order with respect to items already inserted Run time is 0 (n2)

Heap Sort A sorting algorithm that works by first organizing the data to be sorted into a special type of binary tree called a heap The heap itself has by definition the largest value at the top of the tree so the heap sort algorithm must also reverse the order It does this with the following steps1 Remove the topmost item (the

largest) and replace it with the rightmost leaf The topmost item is stored in an array

2 Re-establish the heapRepeat steps 1 and 2 until there are no more items left in the heap

Merge Sort A sorting algorithm which splits the items to be sorted into two groups recursively sorts each group and merge them into a final sorted sequence Run time is 0(n log n)

Bubble Sort Sorting by comparing each adjacent pair of items in a list in turn swapping the items if necessary and repeating the pass through the list until no swaps are done

117

Terminology DefinitionQuick Sort An in-place sort algorithm that uses

the divide and conquer paradigm It picks an element from the array (the pivot) partitions the remaining elements into those greater than and less than this pivot andrecursively sorts the partitions There are many variants of the basic scheme above to select the pivot to partition the array to stop the recursion on small partitions etc

Java Applet Java Applet is a kind of mini-application design to be run by a Java-enabled Web Browser such as Internet Explorer or Netscape Navigator or in the context of some others applet viewer

Java 2 Development Kit

Java 2 SDK is Java development program from Sun Microsystems JSDK will be used to compile and run java program for this project

Java Server Pages JSP is a Java-based technology that simplifies the process of developing dynamic web sites JSP is also a type of server-side scripting language Although there are many server-side scripting languages such as ASP PHP Java Script JSP is the best choice for platformindependent

JAKARTA-TOMCAT Jakarta Project is to provide commercial-quality server solutions based on the Java Platform that is developed in an open and cooperative fashion Simply Tomcat is JSP server Tomcat will receive JSP file execute JSP command and response back to clientJakarta-Tomcat is free and availableon the Internet athttpjakartaapacheorg

118

Terminology DefinitionJava Database Connectivity

JDBC technology is an Application Programming Interface that lets you access virtually any tabular data source from the Java programming language In other words It helps java program to communicate query and update databases JDBC needsJDBC driver as a connector (pipe) between java program and database program There are many vendors provide these drivers
