Program Plan Intro
Hash files:
Hash files use a technique called hashing. Hashing is a technique which provides quick access to record as in indexing but without the expense of index maintenance. In this technique storage is divided into many sections. These sections are called buckets. These buckets are capable of storing many records. These buckets are provided with bucket numbers. These numbers are used to identify buckets rather than keys in indexing.
