ABSTRACT
Employee Management Sytem is a distributed application$ developed to maintain the details
of employees wor#in% in any or%ani,ation" It maintains the information about the personal
details of their employees$ also the details about the payroll system which enable to %enerate the
payslip" The application is actually a suite of applications developed usin% -ava"
It is simple to understand and can be used by anyone who is not even familiar with simple
employees system" It is user friendly and &ust as#s the user to follow step by step operations by
%ivin% him few options" It is fast and can perform many operations of a company"
This software pac#a%e has been developed usin% the powerful codin% tools of -A.A at Front End
and Microsoft '/l 'erver at 0ac# End"The software is very user friendly" The pac#a%e contains
different modules li#e Employee details" This version of the software has multi1user approach"
For further enhancement or development of the pac#a%e$ user2s feedbac# will be considered"

INTRODUCTION TO THE PROJECT
Employee Mana%ement system is an application that enables users to create and store Employee
Records" The application also provides facilities of a payroll system which enables user to
%enerate 8ay slips too" This application is helpful to department of the or%ani,ation which
maintains data of employees related to an or%ani,ation "
-ava is a platform independent lan%ua%e" Its created applications can be used on a standalone
machine as well as on distributed networ#" More over applications developed in &ava can be
etended to Internet based applications"
Thus &ava was chosen as bac#%round to desi%n this application0

OBJECTIVE OF THE PROJECT
In this world of %rowin% technolo%ies everythin% has been computeri,ed" Aith lar%e number of
wor# opportunities the (uman wor#force has increased" Thus there is a need of a system which
can handle the data of such a lar%e number of Employees in an or%ani,ation" This pro&ect
simplifies the tas# of maintain records because of its user friendly nature"

SOFTARE LIFE CYCLE MODEL
The series of sta%es depictin% the various tas#s involved in development process is called
'oftware +ife Cycle Model" The model implemented by us is Aaterfall Model$ which is most
widely used in procedure1oriented development" This model attempts to brea# up the identifiable
activities into series of actions$ each of which must be completed before the net be%ins" The
activities include problem definition$ re/uirement analysis$ desi%n$ codin%$ testin%$ maintenance"
Further refinements to this model include iteration bac# to previous sta%es in order to incorporate
any chan%es or missin% lin#s"
The phases and the outputs of the waterfall model at each phase are summari,ed below in

'oftware development life cycle process specifies a method of developin% the software" Each
software development pro&ects starts with some needs and ends with some software that satisfies
those needs" A software development life cycle specifies the set of activities that should be
preformed to %o from user needs to final products" There are different models of '4+C process
and each model specifies the activities and the order in which they should be preformed"
4ependin% on the nature of pro&ect$ a suitable model is chosen and the entire process of software

LANGUAGE USED % JAVA:
Ja#a is a %eneral computer pro%rammin% lan%ua%e developed by 'un Microsystems" Ori%inally
called JOa#J$ by its inventor -ames !oslin%$ Ja#a was desi%ned with several innovative features"
These include a lan%ua%e that is entirely ob&ect oriented$ and the ability to write an application
once and move it to virtually any platform"
0NNOVAT0ONS
The benefits of ob&ect1oriented pro%rammin% are not necessarily obvious to non1pro%rammers"
Essentially what this means to mana%ers is that code written in Ja#a will be easier to maintain
and reuse in the lon% run" The downside is that ob&ect1oriented pro%rammin% re/uires better
plannin% from the be%innin% of a pro&ect$ and may increase the amount of initial development
time a pro&ect re/uires" For this reason alone$ Ja#a is rarely a %ood choice for small pro&ects
re/uirin% a fast turnaround time"
The second innovation that Ja#a provides$ platform neutrality$ is perhaps the %reatest reason for
its wide acceptance" The fact that Ja#a was ori%inally intended a lan%ua%e for writin% device
controllers for items such as %ara%e openers and microwave ovens is the #ey reason for this" In
practice$ however$ this ability has been more useful in writin% enterprise class business
applications$ where mission critical software may be re/uired to run on a variety of platforms
over its lifetime" Theoretically at least$ once compiled$ a Ja#a binary should be able to run on
any machine that also has a piece of software called a Ja#a .irtual Machine" In reality$ this is not
always the case" (owever$ more often than not Ja#a does succeed in this re%ards$ whereas this is
impossible with an application written in a lan%ua%e such as CKK"
JAVA 0N WE7 DEVELO-MENT
In terms of web development$ Ja#a is fre/uently used in two ways" Most commonly Ja#a is used
to write server1side web applications usin% two technolo%iesD -'8s and servlets" )sin% Ja#a in
this capacity is a %ood choice for comple applications$ that will have lar%e numbers FL6@@@KH of
concurrent users$ and will be developed by a team of pro%rammers" +ess comple pro&ects$ with
fewer concurrent users may have better outcomes when developed in procedural scriptin%
lan%ua%es such as 8(8 or 8ER+"
The second way in which Ja#a is used$ is to create special$ browser embeddable$ pro%rams
called Applets" Ahile applets had a brief period of acceptance$ their use is becomin% increasin%ly
rare$ bein% replaced by a number of technolo%ies such a Flash and -ava'cript$ which are more
effective at providin% desi%n enhancements such as animation and rollovers" )sin% applets for
these purposes is a mista#e fre/uently made by be%innin% developers" 'till$ Applets do have a
place in writin% speciali,ed browser1based applications that cannot be accomplished by these
other technolo%ies" Careful consideration should be made before approvin% any pro&ect that uses
Applets"
12
ORIGIN AND GROTH
+i#e many recently developed computer lan%ua%es$ Ja#a borrows much of its lan%ua%e desi%n
from CMCKK" For that reason$ many pro%rammers who are proficient in those lan%ua%es have
leaned Ja#a$ and provide a lar%e pool of /ualified developers" Ja#a has %ained additional %round
as a first lan%ua%e$ as it is %enerally simpler to master than CKK$ another commonly used
pro%rammin% lan%ua%e"
CLASSES AND O7JECTS
CLASSES
In the real world$ youNll often find many individual ob&ects all of the same #ind" There may be
thousands of other bicycles in eistence$ all of the same ma#e and model" Each bicycle was built
from the same set of blueprints and therefore contains the same components" In ob&ect1oriented
terms$ we say that your bicycle is an instance of the class of ob&ects #nown as bicycles" A class is
the blueprint from which individual ob&ects are created"
O7JECTS
Ob&ects are #ey to understandin% ob&ect1oriented technolo%y" +oo# around ri%ht now and youNll
find many eamples of real1world ob&ectsD your do%$ your des#$ your television set$ your bicycle"
Real1world ob&ects share two characteristicsD They all have state and behavior" 4o%s have state
Fname$ color$ breed$ hun%ryH and behavior Fbar#in%$ fetchin%$ wa%%in% tailH" 0icycles also have
state Fcurrent %ear$ current pedal cadence$ current speedH and behavior Fchan%in% %ear$ chan%in%
pedal cadence$ applyin% bra#esH" Identifyin% the state and behavior for real1world ob&ects is a
%reat way to be%in thin#in% in terms of ob&ect1oriented pro%rammin%"
Ta#e a minute ri%ht now to observe the real1world ob&ects that are in your immediate area" For
each ob&ect that you see$ as# yourself two /uestionsD JAhat possible states can this ob&ect be inOJ
and JAhat possible behavior can this ob&ect performOJ" Ma#e sure to write down your
observations" As you do$ youNll notice that real1world ob&ects vary in compleityP your des#top
lamp may have only two possible states Fon and offH and two possible behaviors Fturn on$ turn
offH$ but your des#top radio mi%ht have additional states Fon$ off$ current volume$ current stationH
and behavior Fturn on$ turn off$ increase volume$ decrease volume$ see#$ scan$ and tuneH" *ou
may also notice that some ob&ects$ in turn$ will also contain other ob&ects" These real1world
observations all translate into the world of ob&ect1oriented pro%rammin%"
'oftware ob&ects are conceptually similar to real1world ob&ectsD they too consist of state and
related behavior" An ob&ect stores its state in fields Fvariables in some pro%rammin% lan%ua%esH
and eposes its behavior throu%h methods Ffunctions in some pro%rammin% lan%ua%esH" Methods
13
operate on an ob&ectNs internal state and serve as the primary mechanism for ob&ect1to1ob&ect
communication" (idin% internal state and re/uirin% all interaction to be performed throu%h an
ob&ectNs methods is #nown as data encapsulation Q a fundamental principle of ob&ect1oriented
pro%rammin%"
0y attributin% state Fcurrent speed$ current pedal cadence$ and current %earH and providin%
methods for chan%in% that state$ the ob&ect remains in control of how the outside world is
allowed to use it" For eample$ if the bicycle only has < %ears$ a method to chan%e %ears could
re&ect any value that is less than 6 or %reater than <"
0undlin% code into individual software ob&ects provides a number of benefits$ includin%D
6" Modula"ity: The source code for an ob&ect can be written and maintained independently
of the source code for other ob&ects" Once created$ an ob&ect can be easily passed around
inside the system"

7" 0n'o"mation6!iding: 0y interactin% only with an ob&ectNs methods$ the details of its
internal implementation remain hidden from the outside world"
9" Code "e6ue: If an ob&ect already eists Fperhaps written by another software developerH$
you can use that ob&ect in your pro%ram" This allows specialists to implementMtestMdebu%
comple$ tas#1specific ob&ects$ which you can then trust to run in your own code"
:" -luggability and debugging eae: If a particular ob&ect turns out to be problematic$ you
can simply remove it from your application and plu% in a different ob&ect as its
replacement" This is analo%ous to fiin% mechanical problems in the real world" If a bolt
brea#s$ you replace it$ not the entire machine"
0N.E10TANCE
4ifferent #inds of ob&ects often have a certain amount in common with each other" Mountain
bi#es$ road bi#es$ and tandem bi#es$ for eample$ all share the characteristics of bicycles Fcurrent
speed$ current pedal cadence$ current %earH" *et each also defines additional features that ma#e
them differentD tandem bicycles have two seats and two sets of handlebarsP road bi#es have drop
handlebarsP some mountain bi#es have an additional chain rin%$ %ivin% them a lower %ear ratio"

Ob&ect1oriented pro%rammin% allows classes to inherit commonly used state and behavior from
other classes" For eample$ Bicycle becomes the superclass of MountainBike$ RoadBike$ and
TandemBike" In the -ava pro%rammin% lan%ua%e$ each class is allowed to have one direct
superclass$ and each superclass has the potential for an unlimited number of subclasses"
0NTE12ACE
+4
As youNve already learned$ ob&ects define their interaction with the outside world throu%h the
methods that they epose" Methods form the ob&ectNs interface with the outside worldP the buttons
on the front of your television set$ for eample$ are the interface between you and the electrical
wirin% on the other side of its plastic casin%" *ou press the JpowerJ button to turn the television
on and off"
In its most common form$ an interface is a %roup of related methods with empty bodies" A
bicycleNs behavior$ if specified as an interface$ mi%ht appear as followsD
interface 0icycle R
void chan%eCadenceFint new.alueHP
void chan%e!earFint new.alueHP
void speed)pFint incrementHP
void apply0ra#esFint decrementHP
S
To implement this interface$ the name of your class would chan%e Fto ACMEBicycle$ for
eampleH$ and youNd use the implements #eyword in the class declarationD
class ACME0icycle implements 0icycle R
MM remainder of this class implemented as before
S
Implementin% an interface allows a class to become more formal about the behavior it promises
to provide" Interfaces form a contract between the class and the outside world$ and this contract
is enforced at build time by the compiler" If your class claims to implement an interface$ all
methods defined
by that interface must appear in its source code before the class will successfully compile"
-ACKAGE
A pac#a%e is a namespace that or%ani,es a set of related classes and interfaces" Conceptually you
can thin# of pac#a%es as bein% similar to different folders on your computer" *ou mi%ht #eep
(TM+ pa%es in one folder$ ima%es in another$ and scripts or applications in yet another" 0ecause
software written in the -ava pro%rammin% lan%ua%e can be composed of hundreds or thousands
of individual classes$ it ma#es sense to #eep thin%s or%ani,ed by placin% related classes and
interfaces into pac#a%es"
The -ava platform provides an enormous class library Fa set of pac#a%esH suitable for use in your
own applications" This library is #nown as the JApplication 8ro%rammin% InterfaceJ$ or JA8IJ
for short" Its pac#a%es represent the tas#s most commonly associated with %eneral1purpose
+1
pro%rammin%" For eample$ a String ob&ect contains state and behavior for character strin%sP a
File ob&ect allows a pro%rammer to easily create$ delete$ inspect$ compare$ or modify a file on
the filesystemP a Socket ob&ect allows for the creation and use of networ# soc#etsP various !)I
ob&ects control buttons and chec#boes and anythin% else related to %raphical user interfaces"
There are literally thousands of classes to choose from" This allows you$ the pro%rammer$ to
focus on the desi%n of your particular application$ rather than the infrastructure re/uired to ma#e
it wor#"

SYSTEM TESTING
4urin% systems testin%$ the system is used eperimentally to ensure that the software does not
fail" In other words$ we can say that it will run accordin% to its specifications and in the way
users epect" 'pecial test data are input for processin%$ and the results eamined" A limited
number of users may be allowed to use the system so that analyst can see whether they try to use
it in unforeseen ways" It is desirable to discover any surprises before the or%ani,ation implements
the system and depends on it"
'oftware modules are tested for their functionality as per the re/uirements identified durin% the
re/uirements analysis phase" To test the functionality of the file transfer and chat application$ a
Guality Assurance FGAH team is formed" The re/uirements identified durin% the re/uirements
analysis phase are submitted to the GA team" In this phase the GA team tests the application for
these re/uirements" The development team submits a test case report to the GA team so that the
application can be tested in the various possible scenarios"
The software development pro&ect$ errors can be in&ected at any sta%e durin% development i"e" if
there is an error in&ected in the desi%n phase then it can be detected in the codin% phase
because there is the product to be eecuted ultimately on the machine$ so we employ a
testin% process"
4urin% the testin% the pro%ram to be tested is eecuted with certain test cases and output of these
test cases is evaluated to chec# the correctness of the pro%ram" It is the testin% that performs first
step in determinin% the errors in the pro%ram"
TEST CASES AND TEST C10TE10A
4urin% Test Cases that are %ood at revealin% the presence of faults is central to successful testin%"
The reason for this is that if there is a fault in the pro%ram$ the pro%ram can still provide the
epected behavior on the certain inputs" Only for the set of inputs the faults that eercise the fault
in the pro%ram will the output of the pro%ram devise from the epected behavior" (ence$ it is fair
to say that testin% is as %ood as its test case"
The number of test cases used to determine errors in the pro%ram should be minimum" There are
two fundamental %oals of a practical testin% activityD1
maimi,e the number of errors detected and"
minimi,e the number of test cases"
As these two %oals are contradictory so the problem of selectin% test cases is a comple one"
Ahile selectin% the test cases the primary ob&ective is to ensure that if there is an error or fault in
the pro%ram$ it is eercised by one of its test cases" An ideal test case is one which succeeds
Fmeanin% that there are no errors$ revealed in its eecutionH only it there are no errors in the
pro%ram one possible set of ideal test cases is one which includes all the possible inputs to the
1-
pro%ram" This is often called Jehaustive testin%J$ however it is impractical and infeasible as
even a small pro%ram can have an infinite input domain"
'o to avoid this problem we use Jtest criteriaJ in selection of the test cases" There are two aspects
of the test case selectionD1
specifyin% a criteria for evaluatin% the test cases
%eneratin% the set of cases that satisfy a %iven criteria"
The fully automated process of %eneratin% test criteria has not been yet found rather %uidelines
are only the automated tool available to us previously" The two fundamental properties for a
testin% criterion areD1
1eliabilityD a criterion is reliable if all the sets that satisfy the criteria detect the same
error" "
ValidityD a criterion is valid if for any error in the pro%ram there is some set satisfyin% the
criteria that will reveal the error"
The fundamental theorem of testin% is that if a testin% criterion is valid and reliable$ if a set
satisfyin% criteria succeeds then the pro%ram contains no errors"
A--1OAC.ES TO TEST0NG
There are two fundamental approaches to testin% they areD
2un&tional Teting=7la&< 7o) Teting D
In functional testin% the structure of the pro%ram is not considered" Test cases are solely
determined on the basis of re/uirement or specification of the pro%ram or module" Internals of
the modules and the pro%rams are not considered for selection of test cases" 4ue to this nature it
is also called Jblac# bo testin%J"
The most obvious functional testin% procedure is Jehaustive testin%J$ which is impractical"
The other criteria for %eneratin% the test case are to %enerate them JrandomlyJ this strate%y has a
little chance of resultin% in a test case that is close to optimal"
There is no appropriate criterion for developin% the test case so we have certain heuristic
approaches1D
aH E*ui#alen&e Cla -a"titioningD in which the domain of all inputs is divided into a set of
e/uivalence classes$ so that if any test in that class succeeds$ then every test in that class will
succeed i"e" the success of one set element implies the success of the other"
bH 7ounda"y Value AnalyiD It has been observed that pro%rams wor# correctly for a set of
values in an e/uivalence class fail on certain values" These values %enerally lie on the boundary
of e/uivalence class" 'o in the boundary value analysis we chose an input for a test case from an
1.
e/uivalence class$ such that input lies on the ed%e of e/uivalence class" 0oundary value test
cases are also called Jetreme casesJ"
cH Caue6E''e&t G"ap!ingD The problem with the prior approaches is that they consider each
input separately i"e" both concentrate on classes and conditions of one input" The combination of
inputs is not considered which is used in many cases" One way to eercise the combination of
various input conditions is to consider all the valid combinations of the e/uivalence class of the
input conditions" The techni/ue starts with identifyin% the causes and the effect of system under
testin%"
ST1/CT/1AL TEST0NG D
In the structural approach the test cases are %enerated an the basis of the actual code of the
pro%ram or the module to be tested$ This structural approach is sometimes called J%lass bo
testin%J$ This testin% is concerned with the implementation of the pro%ram" The content is not to
eercise the various input conditions rather different pro%rammin% structures and data structures
used in the pro%ram"
There are three different approaches to structural testin% they are1 D
aH Cont"ol 'lo$ baed &"ite"iaD
Most common structure based criteria use control flow based testin% in which the control flow
%raph of the pro%ram is considered and covera%e of various aspects of %raph are specified as
criteria" The various control flow based strate%ies are
statement covera%e$
branch covera%e and
all path covera%e
bH Data 2lo$ baed teting:
The basic idea behind the data flow based testin% is to ma#e sure that durin% testin%$ the
definitions of variables and their subse/uent use is tested" To implement the data flow based
testin% the data flow %raph is first made from the control flow %raph"
cH Mutation Teting:
In the above two testin% techni/ues the focus is on which path to be eecuted$ but mutation
testin% is not a path1based approach" The mutation testin% re/uires that the set of test cases must
be such that they can distin%uish between the ori%inal pro%rams and is mutants" In software
world there is no fault model as in hardware so most of the techni/ues do %uess wor# re%ardin%
where the fault must lie and then select the test cases to reveal those faults" In Mutation testin%
faults of some pre1decided types are introduced in the pro%ram bein% tested" Then those faults
are found in the mutants"
1/
0mplementation% E#aluation And Teting
0mplementation is the process of havin% systems personnel chec# out and put new e/uipment
into use$ train users$ install the new application and construct any files of data needed to use it"
This phase is less creative than system desi%n" 4ependin% on the si,e of the or%ani,ation that will
be involved in usin% the application and the ris# involved in its use$ systems developers may
choose to test the operation in only one area of the firm with only one or two persons"
'ometimes$ they will run both old and new system in parallel way to compare the results" In still
other situations$ system developers stop usin% the old system one day and start usin% the new one
the net"
E#aluation of the system is performed to identify its stren%ths and wea#nesses" The actual
evaluation can occur alon% any of the followin% dimensionsD
6" Ope"ational E#aluationD Assessment of the manner in which the system functions$
includin% case of use$ response time$ overall reliability and level of utili,ation"
7" O"gani>ational 0mpa&tD Identification and measurement of benefits to the or%ani,ation
in such areas as financial concerns$ operational efficiency and competitive impact"
9" /e" Manage" Aement: Evaluation of the attitudes of senior and user mana%er
within the or%ani,ation$ as well as end1users"
:" De#elopment -e"'o"man&eD Evaluation of the development process in accordance with
such yardstic#s as overall development time and effort$ conformance to bud%ets and
standards and other pro&ect mana%ement criteria"
Maintenan&e is necessary to eliminate errors in the wor#in% system durin% its wor#in% life and
to tune the system to any variations in its wor#in% environment often small system deficiencies
are found as a system is brou%ht into operations and chan%es are made to remove them" 'ystem
planners must always plan for resource availability to carry out these maintenance functions" The
importance of maintenance is to continue to brin% the new system to standards"
11
CONCLUSION
'ince this pro&ect has been desi%ned eclusively as a pro&ect$ certain compleities that do faced
by any real life manual problem li#e total no" of employee$ address redundancy etc" are
considered in this pro&ect" 0ut enhancement to the pro&ect can easily be made without chan%in%
the current desi%n and pro%rammin% structure"
