The "heart and soul" of almost all relational database programs is the BTree algorithm. In fact may programmers describe a relational database as a BTree program with supporting code that simply delivers the query to the BTree or displays the results from the BTree. The beauty of this book is that it describes in great detail with lots of diagrams and charts exactly how a BTree works. It is one of the clearest explanations on the subject existing and is extremely useful for any person or classroom that is investigating databases. The number of illustrations in this book are too numerous to list. Diagrams are given showing every major step taken in writing a BTree. The diagrams also show exactly how searches are done. Flow charts are also presented showing how the BTree algorithm works. Tables are presented showing the performance of the BTree. Code is listed for an entire BTree program written in simple DOS based BASIC and it is inspected and laboriously explained linebyline.
