For each of the following processes, state whether OLTP or OLAP is appropriate, and why. a.

An insurance company requires a system that will allow it to determine total claims by region, whether a relationship exists between claims and meteorological phenomena, and why one region seems to be more profitable than another. f.

The company has seen no reason to make com- parisons about its operations from year to year or from process to process. Its information needs focus primarily on operations, but it has main- tained backup of prior-year operations activities. Examination of prior-year financial reports has shown that the company, while profitable, is not growing, and return on investment is decreasing. The owners are not satisfied with this situation.
