OSCON: The saga of MySQL

By Robert Kaye
July 24, 2009

At OSCON in 2006, I followed sessions that discussed how open source companies would fare when big corporations come in. Back then there were only a handful of examples of big companies purchasing small open source companies. Three years later, we've witnessed MySQL AB get swallowed by Sun, only to have Sun be swallowed by Oracle. Now there are...

By Andy Oram
July 15, 2009

I recently returned to SQL and Relational Theory: How to Write Accurate SQL Code by C.J. Date, a leading researcher in the field of relational databases, as I learned more about some of the alternative forms of data storage that are becoming popular for Web-based or text-heavy repositories.

Dreaming of Rails as the Next Microsoft Access

Rails? Microsoft Access? Aren't those from different planets? Well, they may have different origins, but their similarities give me hope.

Simple Server Backends for Flex Database Applications

By Jan Poehland
April 17, 2009

Developing Rich Internet Applications that access databases always require a complex infrastructure in the background. The same applies to Flex. Really? What if data can be sent to the server in form of SQL queries without compromising security? This would...

Towards a Plugin Architecture for XRX Web Applications

By Dan McCreary
February 24, 2009

The growth of XRX web application architectures is driving the need for a new generation of web applications standards beyond the scope of the current XQuery specification. These standards promise to allow non-programmers to quickly assemble new web sites from libraries of pre-built XRX applications.

The Relational Model Is Much Misunderstood

By Kathryn Barrett
February 2, 2009

When it comes to relational theory, there is arguably no greater authority than C.J. Date. His newest book, SQL and Relational Theory presents a relational approach to SQL. As he says in the first chapter, "Of course, to treat such a topic adequately, I need to cover relational issues as well as issues of SQL per se." And so the book begins with a foundation that has comparatively little to do with SQL. With these passages, Date sets the scene for a thorough understanding of how SQL is meant to work, and anyone with a background in SQL will benefit from his insights. Even if you don't need the refresher course, it's always a pleasure to read C.J. Date's words.

Test Driving MarkLogic 4.0 XML Server

By Kurt Cagle
November 23, 2008

XML databases have long been something of a niche category in the database world, trying with varying degrees of success to provide the level of ease and accessibility for semi-structured content that is a hallmark of SQL databases, while at the same time providing as much of the sophisticated processing that XPath enables for stand-alone documents. The need is certainly there – a significant amount of the total "data" in the world does not necessarily fall neatly into Ted Codd's relational table structures without significant shredding – yet XML databases have had a hard road to acceptance, in great part because each one offered their own (typically very distinct) mechanism for getting at that data.

MySQL forks: could Drizzle be the next of the new generation of relational database?

By Andy Oram
August 25, 2008

I had a brief talk with leading MySQL develop Brian Aker today about one of the biggest turns in MySQL history: this morning's Drizzle announcement. Brian presented Drizzle as an irrevocable fork of MySQL. To me it represents four deliberate steps in one. Drizzle also calls to mind a lot of the complaints just published by Margo Seltzer in the Communications of the ACM.

February 6, 2008
