I´m gonna build a solution for deliver of gasoline coupons for my workers. It should be developed with visual basic and a SqlServer database. We need 8 CRUDS for catalog tables, such as workers, types of coupons, places they visit as part of their job and others. I need a master detail webform for the input of coupons. One worker can receive several coupons each time. After all the input process I need a detailed report exported in MSExcel format, in order to check the data. I need only the backend part in Visual Basic, because I can build the frontend. There is an Analysis document uploaded.
