Electricity Billing System in C

About this code, I called it Electricity Billing System written entirely in C language. It is a database driven application that uses text files and struct data structure to store and manipulate records in the database. I created this code to show that it is not difficult to write database application using C language.

Payroll System Using Swing in Java and MS Access

About this code, I called it  Payroll System  Using Swing in Java and MS Access it is a database driven application I wrote in Java. The Front End is Java and the depository of Data is MS Access as the Back End. It has also navigational buttons to navigate records in the Database. I have also incorporated the compute button to perform the calculation. This code is very useful for those you are new in JDBC programming in Java.
