Yan Huang - CSCI5330 Database Implementation – Parallel Database

Batch and Transaction Scaleup

Batch scaleup:

A single large job; typical of most database queries and scientific simulation.

Use an N-times larger computer on N-times larger problem.

Transaction scaleup:

Numerous small queries submitted by independent users to a shared database; typical transaction processing and timesharing systems.

N-times as many users submitting requests (hence, N-times as many requests) to an N-times larger database, on an N-times larger computer.

Well-suited to parallel execution.
