On Line Analytic Processing (OLAP)
For today's class, we will be reading two papers:
-
S. Chaudhuri, U. Dayal. An
Overview of Data Warehousing and OLAP Technology. SIGMOD Record
26(1), 1997, pp. 65-74. We are reading this paper because it gives a
good overview of what kinds of processes use OLAP, warehouses, and
decision support in general. Read the rest of the paper, but it's
fine to just skim sections 3 and 4.
- J. Gray, S. Chaudhuri, A. Bosworth, A. Layman, D. Reichart,
M. Venkatrao, F. Pellow, H. Pirahesh. Data Cube: A Relational Aggregation Operator
Generalizing Group-By, Cross-Tab, and Sub-Totals Data Mining and
Knowledge Discovery, 1997. We are reading this paper because it gives
a good example if not the best example of how OLAP differs from
traditional data processing. Read the whole paper, though you can
skip sections 1.2, 3.1, 3.2, 4, and 5.
