Abstract
In this chapter, we discuss the performance of the scan operation. Scan operations search one or more attributes for a certain value. Unless the table is sorted by the attribute to scan, a scan has to iterate over all entries and returns those entries, which fulfill the search predicate (e.g. “SELECT * FROM world_population WHERE lastname = “Smith”).
