Title: Some Critical Data Missing
Review: Perhaps I expected too much from this book. There are three long chapters (166 pages) on updating the data base. What is missing is information and examples on handling the inevitable errors that can occur. Too much time is spent on inept ways developers approach design and not enough time on making a good approach (timestamp) robust by defining appropriate error handling methodology. I typically reuse good examples in my code but I have not found a single routine that I can put into production code.
