most common in data warehouses. However, the most data warehouses use star schema for two important reasons. First, it is the most efficient design because less joint operations are required due to denormalized tables. Second, the star schema is supported by most query optimizers for creating an access plan that use efficient star join
Task Analysis and the Design of Functionality
An important article with this title by [Goransson, Lind, Pettersson, Sandblad, & Schwalbe, 1987] presents several brief case studies that involve failures of functionality design masquerading as usability problems. The most painful is a database system in a business organization that was considered to be too difficult to use.

The objective of this research is to identify the most important design strategies and failure causes that could help prevent latent defects from poor design decision. Latent defects from the most reliable sources were ﬁrst collected and evaluated. Defects that were caused by design were then grouped together for further analysis.

Implementing Database Operations Using SIMD Instructions
We consider the most important database operations, in-cluding sequential scans, aggregation, index operations, and joins. We present techniques for implementing these using SIMD instructions. In some cases, the SIMD implementa-tion is straightforward. In other cases, the SIMD implemen-tation is novel. We demonstrate that signi cant speedups
