While I continue to use MySQL, I am increasingly impressed by PostgreSQL and have begun to use it for a number of consulting projects. I have been impressed by its speed and versatility, as well as its future direction. The improvements between version 6.x and 7.x were staggering, and I look forward to seeing more!
If you are implementing database applications—including web/database applications—under Linux, I encourage you to take a look at PostgreSQL. Even if you decide to stick with MySQL, it is useful to understand how other databases work and why there is such a fuss about transactions, stored procedures and integrity constraints in the community of database programmers. And who knows? Maybe you will also find that PostgreSQL is better-suited to your applications than you think. One of the beautiful things about free software is that you can choose the tools that are best for your needs, and learning about PostgreSQL is a great step in that direction.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
