Product Description

This book is ideal for a course on database applications or as a second book in a course on databases. It is a perfect companion for the software professional in the business of writing database applications. The author expects the reader to be familiar with relational database concepts. The open source MySQL database system is used to illustrate the writing of database applications.

The Database Application Book Using The MySQL Database System Review

I initially obtained this book to help me learn MySQL - building on my prior experience with MS Access, Informix, Sybase and Oracle. What I found was a book loaded with information on relational database principles and features - many that I had never had the opportunity to learn or had forgotten in my 20+ years of database maintenance and development.

Dr. Gehani starts with a brief history of various database models from flat files thru Object and XML databases and various ways of interacting with those models. The detail was just right for me to get a good appreciation of the concepts presented. The author encourages you to research further many of the topics in his book using his references or by searching for other related books or articles.

In chapter 4, Dr. Gehani presents database concepts in mathematical terms. The ideas of projection, selection, cross products, various types of joins as well as set operations are all introduced. In the next chapter, the author gets more into database design and explains the first three normal forms using excellent, concise examples.

The next couple of chapters get heavy into basic SQL as well as transaction processing. The sample database, while very simple in design, is used very well to demonstrate various SQL commands in MySQL. Dr. Gehani goes into great detail in explaining transactions including locks, deadlocks, the phantom problem and starvation. Most of my experience in the business world has involved no transaction processing and many of the concepts were new to me. I found in this chapter that I had to review the samples given a few times as I was doing the exercises at the end of the chapter to be able to understand all the concepts.

The author next discusses constraints, triggers and objects in a concise yet thorough manner. Some of the concepts were very new to me (e.g., the Check constraint and manipulating objects) but again the material is explained very thoroughly in an easy to read style.

Chapter 11 gives a great deal of behind the scenes details on indexing. Many of the concepts like B-trees, hash indexes and dynamic hash indexes I had studied early on in my career and forgotten. Most of the indexing analysis I do in the business world is simply determining which field(s) to place an index on and to measure the change in performance with that index. It was refreshing to review what I had learned so long ago as well as a few new ideas and to gain a better understanding of what is going on in the background with regard to indexes.

The next several chapters deal with security, logs/recovery and replication. In my recent positions, I have not been involved with any of these areas but I did find it very informative to read about them and to work through the examples to help me understand how my databases are kept secure and how they can be recovered if there is any corruption of my data.

The final chapter is on performance tuning which is a big part of what I do in my current job. Various concepts are discussed to improve performance including hardware upgrades, table joins, de-normalizing tables, pre-computing queries and indexing tables. Again, the examples in MySQL are well thought out and get the point across in a very understandable way.

Dr. Gehani states in his preface that his goal is to give database users, designers, administrators and application programmers the same level of understanding of database concepts and fundamentals as traditionally given to people learning how to implement database systems. He has certainly met this goal in the writing of this book. This book now sits on my desk at work where I find myself rereading various chapters or sections as well as using as a quick reference on a regular basis.

Database Design for Smarties: Using UML for Data Modeling (The Morgan Kaufmann Series in Data Management Systems) Review

Database Modeling for Smarties is exactly that. This book captures the techniques that I have been using for a number of years but have not been able to capture concisely. I found the discussion of object-relational mapping very useful and would love to send copies to the database designers that I work with. The reading is easy and the only negative would be that the chapter on development team values & characteristics seems to be misplaced. However the chapter was good reading as an intermission in the middle of the book.

The Day Trader's Course: Low-Risk, High-Profit Strategies for Trading Stocks and Futures (Wiley Trading) Review

What a disappointment! Almost nothing of real value. Of the many dozens of books on daytrading, and I own most of them, only a handful present useful information that you can actually utilize. Tony Oz, Jea Yu, Joe Dinapoli, Toni Turner and Linda Raschke are your best sources. I intend to either return this waste of paper and ink or sell it. Frankly I would hate to rip someone off so I hope I can return it for a credit. I had high hopes, I even ordered this six weeks before it was published.

Product Description

Susanne Bobzien presents the definitive study of one of the most important intellectual legacies of the ancient Greek world: the Stoic theory of causal determinism. She identifies the main problems that the Stoics addressed and reconstructs the theory. She discusses how the Stoics squared their determinism with their conceptions of possibility, action, freedom, and moral responsibility, and how they defended it against objections and criticism by other philosophers. She shows how
the Stoics distinguished their causal determinism from ancient theories of logical determinism, fatalism, and necessitarianism. Along the way she gives an authoritative account of many other related aspects of Stoic thought, including their views on the predictability of the future, the role of
empirical sciences, the determination of character, and moral freedom. Bobzien's study of these central doctrines of Stoicism reveals the considerable philosophical richness and power that they retain today.

Determinism and Freedom in Stoic Philosophy Review

Determinism and Freedom in Stoic Philosophy is truly remarkable scholarship, illuminating, philosophically inspiring and highly recommended.

Bobzien traces the Stoic theory of causal determinism to its beginnings and discusses its connection with their views on freedom, action, and moral responsibility. The book is, however, more than a book on the history of philosophy; it is a book on philosophy and is, indeeed, philosophically rewarding.

This book is highly recommended not just for those intereseted in Stoicism, Hellenistic philosophy or Ancient philosophy generally, but also for anyone interested in contemporary debates about determinism and questions about free will.

Product Description

Teachers are expected to take responsibility for children's moral development, particularly in the primary years, but how best to go about approaching the issues? In this book, the author explores a classroom approach that uses both drama and narrative stories to explore moral issues: drama gives children an opportunity to work through moral problems, make decisions and take up moral positions; stories offer a resource for moral education whereby children can learn through the 'experiences' of those in the story. Through providing a number of case studies, the author shows how this may be done by practitioners in the lassroom.

Drama, Narrative and Moral Education Review

This book has enriched my thinking around what I do - that there is a moral imperative in my work.
