In the old days, before SQL and Relational and all that, not when Vikings toured the world, drinking, being violent and causing mayhem, but still in the old days, the databases in use, the first reasonably generic database systems, were Hierarchical or Network based. These had a strict schema and data was extracted by navigation (i.e. Find company X, find orders for company X, find items etc.), and there was no way of searching data (which wasn't much of a problem, as data was largely stored on tape anyway, which isn't really searchable in the now common sense).

When SQL came around, the relations style schema allowed a much more free way of navigating data, and it also allowed searching. The SQL search as we know it is still contextual (i.e. you have to specify what to search, a SELECT from a customer table based on address, will not retrieve employees with a matching address). All the same, when SQL came around, the ability to search …

The end of the killer feature by Scott Berkun. Scott will be speaking at WordCamp San Francisco 2010.

Edward Screven – Chief Corporate Architect of Oracle provided the opening keynote at the 2010 MySQL Users Conference.

Overall I was disappointed. The first half was more an Oracle Sales pitch, we had some product announcements, we had some 5.5 performance buzz. While a few numbers and features were indeed great to hear, there was a clear lack of information to the MySQL ecosystem including employees, alumni and various support services. I hope more is unveiled this week.

Some notes of the session.

• Oracle’s Strategy covers storage, servers, virtual machines, operating system, database, middleware, applications
• We build a complete technology stack that is “open” and “integrated” based on “open standards”
• products talk via open standards with the intention for customers to not feel locked in to any technology

Just so you know, those at and those not at the MySQL User Conference, no, MySQL / Sun / Oracle hasn't been acquired. It feels real strange to have been not-acquired for such a long time, about a year now, but I guess I have to learn to live with it. And the User Conference isn't over yet, so who knows what will happen. I mean, not MySQL has taken control of Oracle, Sun, InnoDB, TimesTen and many other application, but we still have a few more companies to get control over.

Where MySQL fits within Oracle’s structure.

Oracle’s Strategy: Complete. Open. Integrated. (compare with MySQL’s strategy: Fast, Reliable, Easy to Use).

Most of the $$ spent by companies is not on software, but on integration. So Oracle makes software based on open standards that integrates well.

Most of the components talk to each other through open standards, so that customers can use other products, and standardize on the technology, which makes it much more likely that customers will continue to use Oracle.

Oracle invested …

Some of you might have seen my post on the MySQL Audit API that is included with MySQL 5.5 m3 and some of you might not have. Well, the code that is part of that is real simple, it's more to show a concept than something you would want to run in your production servers. But it was an attempt to check if there was any interest in something like this. And there was.

So I will develop this further into something much more useful. I have had several comments and suggestions already, and keep those coming, and I am listening. What I will implement for sure in an upcoming first release is four things:

• More configurability and status.
• Means of turning the plugin on and off.
• More data provided through the INFORMATION_SCHEMA table.
• Some means of limiting and controlling …
