 A Java tool (or can also be used as a library) that takes care of all the nitty-gritty that needs to be done when a sensor has generated data and you want to find that data in a database. Hence _data collect alter forward store_. If the device needs to be interrogated or any other sort of control, that's also possible (hidden under _forward_).   
 That is in broad terms what it is capable of.
