C. J. Date is one of the founding fathers of the relational database field. Of all the early leaders, Date is by far the most prolific, and is arguably the most authoritative (Even today "Date says" carries a lot of weight). Many of today's more seasoned database professionals "grew up" on Date's writings. Those same professionals, along with other serious database students and practitioners, form the core audience for Date's ongoing writing efforts. Date on Database: Writings 2000-2006 is a compilation of Date's most significant articles and papers over the past seven years. It gives readers a one-stop place in which to find Date's latest thinking on relational technology. Many papers are not easily found outside this book. Readers who want the material will gladly pay the price for the book.
