Less than two weeks ago, I posted my Database Survey. As of just a few minutes ago, I have had 215 responses. That’s pretty awesome. I’d like to get at least twice that though.

I haven’t looked deeply at it yet to see if there are any trends. I think it will be best to wait until the survey is closed. I did look at some of the responses, kind of as a quality check. Looks like MySQL is fairly well represented. I didn’t see any DB2 responses (for primary database).

Infoworld published the 2008 Bossies, Best Of Open Source Software. There are 8 categories and none of them are database:

• Collaboration
• Developer tools
• Enterprise applications
• Networking
• Platforms and middleware
• Productivity applications
• Security
• Storage

I had to look through several of them before I found the database category under Platforms and middleware. Slide 4 is the magic slide:

It says:

When I first read about this book, I figured many sections would be over my head. I was pleasantly surprised when I started reading it.

Hot on the heels of news that SquareSpace is using Oracle, comes news that LinkedIn is going whole hog with MySQL.

Actually, you could say that LinkedIn is buying into Sun. They are buying the MySQL Enterprise subscription and they’ll be running MySQL on Sparc servers and Solaris 10. They’ve signed up for Sun Professional Services, MySQL Professional Services, and Solaris Everywhere. I guess you could say that signed up for the full monty. Pun intended.

“Helping LinkedIn to scale their Web systems demonstrates the strength of combining the Sun and MySQL teams,“ said Zack Urlocker, vice-president of products, database group, Sun Microsystems.

I recently posted about the results of the EDB Open Source Survey. It doesn’t look like the raw data is going to be released. I was also reading about an O’reilly survey that costs $350 to see. Not that I am opposed to them making money, but I wanted to see the results and I think there are a lot people who feel the same. I have no idea if my survey is anything like O’reilly’s.

Anyway, I have created a new survey. It has about 10 demographics questions asking who you are, where you are, what kind of role you have, etc.

Hi. I’ve created a 25 question survey on databases and open source. There are about 10 demographic type questions (who are you, where are you, etc) and then a bunch of questions on databases and open source.

The results of this survey, and by results I mean all of the raw data, will be released to the public at the completion of the survey.

I ask for an email ID so that I can send you the results. This is totally optional and you will still be able to get the results should you chose not enter one.

I didn’t get a chance to go to OSCON 2008. Bummer. But I can live vicariously through google. So, along with all of the announcements you’ve heard from OSCON, I know present the OSCON 2008 – Google popularity contest. This is a completely unscientific survey of google hits. I was searching blogs and news. I started with just news but the blogs hits really upped the numbers.

To run these searches, I use “oscon 2008″ and the search term, for example:

“oscon 2008″ mysql

In the case of open source, I also quoted “open source”.

I’m using google’s about number. I didn’t sit and count each hit.

Yesterday I posted about the results of the EnterpriseDB open source survey. In that post, I said:

I’d like to see the survey again and compare the results to the survey itself.

I discovered that, as of right now, the survey is still online.

Still no information as to when, or if, the entire survey results will be released. That’s what I am most interested in.

Have you heard of Drizzle? It was announced at OSCON yesterday and is all over the blogosphere. From the Drizzle FAQ:

* So what are the differences between is and MySQL?

No modes, views, triggers, prepared statements, stored procedures, query cache, data conversion inserts, ACL. Fewer data types. Less engines, less code. Assume the primary engine is transactional.

Also from the FAQ is that, right now at least, there is no intention to make this run natively on windows and they make the point:

* “This is not a SQL compliant relational…”

Very true, and we do not aim to be that.

It is a fork of MySQL that takes it backward to pre-5.0 in features but hopefully greatly reduces the bugs and instabilities.

EnterpriseDB announced the results of the survey they did a few months ago at OSCON. Now, take the results with a grain of salt as it was done by EnterpriseDB. EnterpriseDB is based on Postgres so there is a vested interest in making Postgres sound good. Results can be skewed depending on how the survey is worded, what options are available as answers and who the respondents are.

The results summary is available for free.

Some key facts:

500 respondents. The download page says “500 corporate IT leaders”. Or maybe, 500 open source developers.

Only 9% of respondents indicated that they preferred commercial solutions over open source solutions.

I was browsing the web on this lazy Sunday afternoon and ran across a good article on the Rarest Words blog. The author was trying to get Django installed and running with Postgres. From the author’s own admissions, he is not a Postgres fanatic.

Well, this and last year I hear everywhere that PostgreSQL is the way to go and that usage of mySQL in 2008 makes people puke… But without any real arguments (besides “Postgres is the way to go”).

After some not so compatible errors with these not so compatible databases, the author did get it working and ran some benchmarks. Postgres did not turn out faster than MySQL.

The datastore in Postgres (which is what Advanced Server is based on) is quite a bit different than the way Oracle stores data. Gone are the usual logical storage components. Data blocks, extents and segments just don’t exist in a Postgres database. Actually, segments do exist when a table gets bigger than 1GB but that’s a story for a different entry.

Postgres stores data as files and directories. Tablespaces are directories and tables (and indexes) are files inside that directory. Postgres ships with two tablespaces installed by default: pg_default and pg_global. The tablespaces cannot be changed or dropped.

Sun just announced MySQL Workbench, a new database design tool for MySQL developers and DBAs. I’m a data modeling tool junkie. I like to play with any I can get my hands on. I’ve used almost every modeling tool that’s been built. My all time favorite is probably Erwin.

I decided to download MySQL Workbench and give it a try. Since I was playing with it, I figured I should write about it and while I am writing about it, I might as well write about a couple of other tools, that I have personally used, that you might like.

TOAD Data Modeler

The TOAD Data Modeler from Quest used to have a free version.

EnterpriseDB News at Blogspot

Chris Keene, the CEO for Wavemaker just blogged that combining Wavemaker and EnterpriseDB just got easier. Wavemaker has a new version that has out of the box support for both Postgres and EnterpriseDB.

I wrote a couple of weeks ago about my first day of Wavemaker training. I still haven’t found time to start day two but now that Wavemaker supports EnterpriseDB, I’ll probably redo day 1 using Advanced Server instead of MySQL. I could have done it before since it already supported Postgres and EnterpriseDB via a manual configuration.

According to an article at Computerworld, Yahoo is running a 2 PB (not GB, not TB, PB – Petabyte) database that processes 24 billion events a day. Let’s put that in perspective. 24 billion events is 24,000 million events; 24,000,000,000 events. 1 petabyte is 1,000,000,000,000 bytes. Yahoo has two of those. Actually, I should be basing this on 1k which is 1024 but when you’re dealing with petabytes, I don’t think we need to be picky. We’re talking really, really big.

Yahoo uses this database to analyze the browsing habits of it half a billion monthly visitors.

Do you know which open source feature is the most important? Do you know which open source database rocks and which one sucks? Is MySQL better than Postgres? Is Ingres worth considering? How does Firebird compare? Have you used, or have you considered using, an open source database?

Take a survey. It’s only 15 questions so it takes just a few minutes.

I’ll post a link where you can get the results once they have been compiled and prepared.

BTW, this isn’t my survey. I’m just passing on the link.

I mentioned the other day that I was playing with a new GUI builder from an EnterpriseDB partner, Wavemaker. Wavemaker, in addition to providing the software, provides some training that is downloadable from the web site.

This training is a two day basics course in powerpoint format. I would guess that this is what they use for instructor led training and they just made this available to the public. Anyway, I decided to see how good the training was which in turn kind of tells me how easy wavemaker is to learn.

Day 1 includes 8 powerpoint presentations:

• Introduction
• Wavemaker Architecture
• Wavemaker Installation
• Wavemaker Studio Overview
• Page Designer Basics
• Wavemaker Data Model
• Service Components
• Data Widgets

Seeing as how I was already making some simple pages with the tool, I blew through the intro, the architecture and installation.

I wrote about GridSQL and EnterpriseDB a while back. EnterpriseDB bought GridSQL (from Mason who now works at EnterpriseDB) and has been working to improve it. Yesterday, they announced that they are open sourcing it.

GridSQL is really for data warehousing but can be applied to some OLTP/reporting combination databases. What it does is take a query and spread it out to run in parallel against a set of cheap PCs. There is a controller machine, called a coordinator, that keeps track of what is running and where.

Because there is a central point of failure (the coordinator), it is not a high availability solution.
