Please post DDL, so that people do not have to guess what the keys,
constraints, Declarative Referential Integrity, data types, etc. in
your schema are. Sample data is also a good idea, along with clear
specifications.
I am a little confused on this. Aren't "acceleration", "speed", and
"weight" attributes and not values? Surely you are not mixing
meteadata and data.
