I am going to build a Accounting and Inventory based Software for My Printing Press office. I was thing to use JDBC and Excel at the back-end. The Entries was huge, sometimes thousands entries has to be made in a week. this software will show us the current inventory, sales, expenses, and on the base of sale and expenses, it will help us to forecast future sales and employees or inventory performance.
I want some Suggestion of all you experience software developer whether or not should i use this platform or any-other. I only knows J2SE, JDBC, PHP, MySQL Assembly and Ms Access and Excel.
