I asked for information on Database Machines and Database accelerators
in the market 3 weeks ago. I am particularly interested in the following:
1. What database machines are currently available in the market?
2. What kind of applications in which they are used? In particular, what
are the sizes of the relations being processed? cardinality? tuple size?
What is the (approximate) number of relational operations involved to
solve a problem? tens? hundreds? thousands? or more?
3. How is their performance compared with software DBMS?
Only one reply was received. Now I post it for whoever interested in
this subject.
