External Perfect Hashing
In this chapter, we give some theoretical and experimental results for the most popular practical algorithms for constructing perfect hashing functions, suitable for key sets ranging in size from very small to very large ones, i.e. in the order of millions. These algorithms are used for a variety of applications such as in DBMSs, retrieval systems and file managers, as well as in compilers, natural language applications, hypermedia and hypertext to provide rapid access to internal and external data collections.
