Scale, barcode and database.

The item will arrive on the scale. The operator will stick a label on the product and then pass the barcode reader. With this, the system to be created will take this sequential number from the barcode, the weight on the scale and the time of data capture. This captured information must be made available dynamically. And store for later reference. It must be stored as a list, with the information of the barcode reading. The information about the weight of the scale and the last time and date of the reading. in case of repetition in the same bar code, overwrite the previous and hourly weight value, not generating duplicate information.
