I work in a supermarket as an accountant in charge of operating a software system that I design myself. It is a sales software designed for the supermarket is responsible for reading the section of Mercedarian bar codes, cleaning section, reads the barcodes that throw the balance of the deli section, Section of carnage . etc. This software is made in java uses mysql wifi connections, windows operating system and a linux operating system that uses as a database server 8 computers. Uses two computers are connected wi fi either to upload data to databases or to view sales report, personnel control reports, and accounting reports. And also used phones with applications made in java android. Very useful to find out prices and control of the sales in the cashiers employees.
