INTRODUCTION
The project is designed to keep records of Employee in specific
department and post who are working in these companies. A table named
empdata in MYSQL5.0 to store information about employee Name,
Contact, Address, Post, Salary with Employee ID.
Administrator of the project can enter new record, Display all or specific
passenger record; he can modify and delete records in any table.
OBJECTIVES OF THE PROJECT
The main objective of this project is to learn the application of the
programming knowledge into a real- world situation/problem and
exposed the ourselve how programming skills helps in developing a
good software.
1. Write programs utilizing modern software tools.
2. Apply object oriented programming principles effectively when
developing small to medium sized projects.
3. Write effective procedural code to solve small to medium sized
problems.
4. To make file handling easy by using programs

PROPOSED SYSTEM
Today one cannot afford to rely on the fallible human beings of be really
wants to stand against today’s merciless competition where not to wise
saying “to err is human” no longer valid, it’s out-dated to rationalize
your mistake. So, to keep pace with time, to bring about the best result
without malfunctioning and greater efficiency so to replace the
unending heaps of flies with a much sophisticated hard disk of the
computer.
One has to use the data management software. Software has been an
ascent in atomizationvarious organisations. Many software products
working are now in markets, which have helped in making the
organizations work easier and efficiently. Data management initially
hadto maintain a lot of ledgers and a lot of paperwork has to be done
but now software producton this organization has made their work
faster and easier. Now only this software has to beloaded on the
computer and work can be done.
This prevents a lot of time and money. Thework becomes fully
automated and any information regarding the organization can
beobtained by clicking the button. Moreover, nowit’s an age of
computers of and automatingsuch an organization gives the better look.

TESTING
Software Testing is an empirical investigation conducted to provide
stakeholders with information about the quality of the product or
service under test[1] , with respect to the context in which it is intended
to operate. Software Testing also provides an objective, independent
view of the software to allow the business to appreciate and understand
the risks at implementation of the software. Test techniques include, but
are not limited to, the process of executing a program or application
with the intent of finding software bugs.
It can also be stated as the process of validating and verifying that a
software program/application/product meets the business and
technical requirements that guided its design and development, so that
it works as expected and can be implemented with the same
characteristics. Software Testing, depending on the testing method
employed, can be implemented at any time in the development process,
however the most test effort is employed after the requirements have
been defined and coding process has been completed.
TESTING METHODS
Software testing methods are traditionally divided into black box
testing and white box testing. These two approaches are used to describe
the point of view that a test engineer takes when designing test cases.
BLACK BOX TESTING
Black box testing treats the software as a "black box," without any
knowledge of internal implementation. Black box testing methods
include: equivalence partitioning, boundary value analysis, all-pairs
testing, fuzz testing, model-based testing, traceability matrix,
exploratory testing and specification-based testing.
SPECIFICATION-BASED TESTING
Specification-based testing aims to test the functionality of software
according to the applicable requirements.[16] Thus, the tester inputs
data into, and only sees the output from, the test object. This level of

16. [14]
testing usually requires thorough test cases to be provided to the tester,
who then can simply verify that for a given input, the output value (or
behaviour), either "is" or "is not" the same as the expected value
specified in the test case. Specification-based testing is necessary, but it is
insufficient to guard against certain risks.
ADVANTAGES AND DISADVANTAGES
The black box tester has no "bonds" with the code, and a tester's
perception is very simple: a code must have bugs. Using the principle,
"Ask and you shall receive," black box testers find bugs where
programmers don't. But, on the other hand, black box testing has been
said to be "like a walk in a dark labyrinth without a flashlight," because
the tester doesn't know how the software being tested was actually
constructed.
That's why there are situations when (1) a black box tester writes many
test cases to check something that can be tested by only one test case,
and/or (2) some parts of the back end are not tested at all. Therefore,
black box testing has the advantage of "an unaffiliated opinion," on the
one hand, and the disadvantage of "blind exploring," on the other.
WHITE BOX TESTING
White box testing, by contrast to black box testing, is when the tester has
access to the internal data structures and algorithms (and the code that
implement these)
Types of white box testing:-
api testing - Testing of the application using Public and Private
APIs.
Code coverage - creating tests to satisfy some criteria of code
coverage.
