If parallelism is taken to its ultimate conclusion, it becomes a distributed database, adopting either a fragmentation schema or a fully replicated schema to implement the distribution.

Grid environments distribute processing over a flexible number of computers to take advantage of the added horsepower to meet the peak computing needs. This means that several processes are running in parallel on the different systems. Programming logic gets distributed across systems, control gets distributed across systems, and the data required for processing gets distributed across systems.
