Object relational mappers are popular, because the software disguises the impedance mismatch between objects and databases. There are many ORM variants to choose from, but many simply get in the way when you need to do something the ORM wasn’t expressly designed to do. SQLALchemy is different. It aims to provide you with objects that look and act like real objects, and data sets that provide the full power and flexibility of relational algebra. Here’s a tour.
Take a look at Perl's confusing, but important pack and unpack functions.

Let's face it: in the business world, you're bound to encounter individuals who just can't get "the big picture." At the sight of rows and columns of data, their brains disconnect, their eyes cross, their breathing becomes labored, and they pass out. But wouldn't it be nice to avoid all that trauma?

Master/slave replication first appeared in a beta release of MySQL back in 2000. In the three or so years since then, replication has become an essential feature for most of MySQL's high-end users. And contrary to many assumptions, MySQL's replication is quite easy to use, especially when compared to the replication systems that are part of high-end commercial databases. This month and next, let's take a look at MySQL's replication feature and the various ways you can put it to use.
Take a hands-on tour of stored procedures, views, and triggers, just three of the new features found in MySQL 5.

Last month, we looked at adding search to a site using the open source ht://Dig search tools. As you'll recall, ht://Dig handles the crawling, indexing, and search duties.

If you're a well-seasoned Net surfer, you've undoubtedly noticed that the number of "community" Web sites run by individuals, small companies, and other organizations has increased dramatically over the last few years.

Believe it or not, IT departments shudder at the words "Let's deploy Exchange." Although Microsoft's email server is virtually ubiquitous, that doesn't mean it's popular with those that have to manage it. So before your boss writes a hefty check for Exchange and sentences you to countless hours of hard labor, speak up and suggest one of the many open source substitutes that are just as robust as Exchange -- and are free!
