7. TECHNOLOGIES USED
1. Java
Java is Platform Independent, Secure, Object Oriented, Scalable, and Robust
Programming Language.
It consists of two parts
JVM stands for Java Virtual Machine, which is run time environment to execute the
java programs.
Java API (Application Programming Interface) that consists of inbuilt classes used in
java programs.
Java is a set of several computer software products and specifications from Sun
Microsystems (which has since merged with Oracle Corporation), that together provide a
system for developing application software and deploying it in a cross-platform computing
environment. Java is used in a wide variety of computing platforms from embedded devices
and mobile phones on the low end, to enterprise servers and supercomputers on the high end.
While less common on desktop computers, Java applets are sometimes used to provide
improved and secure functions while browsing the World Wide Web.
Writing in the Java programming language is the primary way to produce code that will be
deployed as Java bytecode. There are, however, bytecode compilers available for other
languages such as Ada, JavaScript, Python, and Ruby. Several new languages have been
designed to run natively on the Java Virtual Machine (JVM), such as Scala, Clojure and
Groovy. Java syntax borrows heavily from C and C++, but object-oriented features are
modeled after Smalltalk and Objective-C. [6] Java eliminates certain low-level constructs
such as pointers and has a very simple memory model where every object is allocated on the
heap and all variables of object types are references. Memory management is handled
through integrated automatic garbage collection performed by the JVM.
2. JDBC (Java Database Connectivity)
It is an API, which is used for the communication of java programs with different
databases. JDBC is a Java-based data access technology (Java Standard Edition platform)
from Sun Microsystems. It is an acronym as it is unofficially referred to as Java Database
Page 7 of 37

8. Connectivity, with DB being universally recognized as the abbreviation for database. This
technology is an API for the Java programming language that defines how a client may
access a database. It provides methods for querying and updating data in a database. JDBC is
oriented towards relational databases. A JDBC-to-ODBC bridge enables connections to any
ODBC-accessible data source in the JVM host environment.
3. Windows Programming
Swings in java is a rich set of components for building GUIs and adding interactivity
to java applications.
Swing includes all the components that you would expect from a modern GUI toolkit
that is table controls, list controls, tree controls, buttons and labels. The basic architecture of
swing is MVC, and are entirely made in java.
4. MySQL
MySQL is used as database, used to store data. It is RDBMS.

We used MYSQL as the backend and used JDBC connectivity to access the database. The
java application access the database using JDBC and output the results according to the
query, which again takes into account the options, selected by the user.

37. CONCLUSION
This project is useful to those who have to maintain large stock records with transaction
records with others. This project is particularly for the pesticide shop those deal with different
products of different companies but can be modified for the use of other type of business that
have similar requirements. In routine , operations such addition of items to stock, change of
price of items frequently occur, this project provides easy interface to accomplish this task
and saves the time and there is daily to daily transactions with companies and retailers and to
maintain all records of transactions, this project provides all information.
FUTURE SCOPE OF WORK
Many businessmen who even today maintain all records with the help of pen and paper
It is too tough to maintain the records with the use of paper as it requires lot of space to
maintain and store all the records so chances of error increases as records increases.
In the case to match the stock record with the actual sales it is easy if it is computerized.
