Clone of the given Software

I purchased? an application from a private company three years back for around $30. It works well but i am facing few problems in reports generation and data sorting. I want to have a exact clone of the application with some improvements. I want the same database to be used so that i don't have to enter the records again or if the programmer wants to use the new database he has to develop a mediator software so that all my old records should be transferred to the new database. I will appreciate your comments and further queries. ## Deliverables Please go through the attached .zip files for reference.
