Summary: Spatiotemporal databases area good for applications in space and defense but historically suffer from performance issues. the way that databases work now is we store data about the known world, stuff that does not change or changes infrequently. we have been able to monitor moving objects but not with great effiency. since something is always in motion is has to be updated for every unit of time. planes are always moving and their position changes every second so running querries every second for multiple objects is very resource intensive and databases suffer from it. this type of database uses new techniques in order to efficiently process data. this having one table for every object tracked, frequent data updates and reduced querying. when spatial database software improves then you will see more applications in space and defence.
I thought this was an interesting journal because it is about databases but its about more in depth databases that require massive inputs in order to do its job. this group managed to be able to make a relatively efficient spaciotemporal database. it is interesting about what we do keep in databases, things like photos, and other non changing information and how we worry about performance issues when there is other fields who REALLY need to worry about performance issues when it comes to their ever changing data. so yea i do think that this is pretty cool because we can use this type of idea to monitor space junk, and predict its impact with the earth or when it just releases from the earths pull and heads for the moon. either way if we do have these type of systems we will be better equiped to catalog the things arround us.
