Search within a Page
Three families of strategies for organizing an index of ordered keys are investigated. It is assumed either that the index is small enough to fit in main memory or that some superstrategy organizes the index into pages and that search within a page is being studied. Examples of strategies within the three families are B-tree Search, Binary Search, and Square Root Search. The expected access times of these and other strategies are compared, and their relative merits in different indexing situations are discussed and conjectured on. Considering time and space costs and complexity of programming, it is concluded that a Binary Search strategy is generally preferable.
