Idea of Jam storage – is a web application that keeps information about all jars of jam stored at home. When one receives from a granny few jars of strawberry jam – he adds information about them into database. It is possible to write amount of jars, type of jam, year of production and some comment. Then later, when some jar of jam is eaten away, there is possibility to remove one jar from storage. And after sweet meal, one can have an overview of jams he didn’t eat yet.
