Welcome to the 102nd edition of Log Buffer, the weekly review of database blogs.

Since it was DB2’s 25th birthday this week, as Anant Jhingran reports, let’s start with it.

From ZDNet this week came a story that IBM was considering the open-sourcing of DB2 — big news, naturally, whether true or not. Matthew Aslett of 451 CAOS Theory says, Open source DB2? I don’t think so, suggesting that it was merely theorizing on the part of one IBM …

Welcome the the 101st edition of Log Buffer, the weekly review of database blogs.

This edition was originally claimed by Ward Pond for his SQL Server Blog. Unfortunately, Ward is, in his own words, “dealing with the aftermath of a burst appendix,” which is a very good reason not to spend your time at the computer. Ward, heal up soon! We’ll see you on LB before too long.

In lieu of the normal Log Buffer, I throw it open to our readers. Please leave a comment mentioning your favourite database blog items from the week that was, and anything else you care to say about them.

LB will be back to normal next Friday. See you then!

Log Buffer, the weekly review of database blogs, is 100 editions (and almost two-years) old today! Lewis Cunningham has returned to LB to publish The Big 100th edition of LB on An Expert?s Guide to Oracle Technology.

No speech, but I would like to thank Log Buffer’s readers and especially all of Log Buffer’s editors for making LB a worthwhile and fun stop in the database “blogosphere”. It’s very easy to see why LB editors are successful in what they do — they are consistently enthusiastic, diligent, and adaptable. And I enjoy working with them.

Okay, okay — I can hear the orchestra starting to play me off, so …

Welcome the the 99th edition of Log Buffer, the weekly review of database blogs.

Since PGCon recently happened right here in Ottawa, let’s start with some posts about it, and about PostgreSQL. Josh Berkus came to the conference with his Database Soup. It sounds like he enjoyed himself: “So, that’s pgCon. It was exciting and fun. All of you PG geeks who missed it should be kicking yourselves about now, and putting in budget requests for next year.” He has day one highlights; day two highlights, and also …

The 98th edition of Log Buffer, the weekly review of database blogs, has been published on Jeff’s SQL Server Blog.

Log Buffer is a shared project of the DBA blogging community, so you’re welcome to edit and publish an edition yourself. LB’s 100th anniversary edition is still up-for-grabs (and there’s plenty of room besides that), so read the Log Buffer homepage and the guidelines, and then email me.

Here’s Jeff Smith’s …

There are a few podcasts I tend to listen to as I have time. Since I work with a wide range of technologies, I've tried to group them together into a semblance of order. There are a few others I am evaluating, but since I haven't listened to a large enough body of work, I'll refrain from listing them at this time. If there's one you think is particularly valuable or interesting that I don't have listed, please leave it in the comments.

.NET Rocks - http://www.dotnetrocks.com/

This is one of the best done podcasts out there and they cover anything and everything related to Microsoft .NET. That's a broad brush of most anything that interacts with Microsoft technologies. This one runs twice a week and is about an hour each podcast, but if you can spare the time, it's worth the listen.

The 97th edition of Log Buffer, the weekly review of database blogs, has been published on Brian “Krow” Aker’s Idle Thoughts.

We have Jeff Smith and Ward Pond standing by for two upcoming editions. And if you’d like to contribute, make yourself known in the DBA community-at-large (and have some fun in the process), you too can do Log Buffer! Read the homepage and send me, the Log Buffer coordinator, an email.

And now, Brian …

Contemporary software engineering models include many loosely-defined layers. Database developers might help with other layers, but for the most part a database administrator’s domain is the persistence layer.

• 
  
• Presentation
  
• Application
  
• Business Logic
  
• Persistence (also called Storage)
  

The Daily WTF has an article on The Mythical Business Layer makes the case for not separating the business layer and the application layer:

A good system (as in, one that’s maintainable by other people) has no choice but to duplicate, triplicate, or even-more-licate business logic. If Account_Number is a seven-digit required field, it should be declared as CHAR(7) NOT NULL in the database and …

This is the 96th edition of the weekly review of database blogs, Log Buffer.

Let’s start this one in SQL Server Land, with a question from Dennis Gobo — should SQL Server have the CREATE [OR REPLACE] PROCEDURE syntax? There are, he writes, advantages: “When scripting out a database you don?t have to generate if exists…..drop statements,” and disadvantages: “I can overwrite a proc without even knowing it.” Of course, the commenters have opinions of their own, and the piece becomes a straw poll for the desirability of that syntax as a feature.

Aaron Bertrand has one too: …

The 95th edition of Log Buffer, the weekly review of database blogs, has been published by Mark Schoonover on his Mark’s IT Blog.

We can look forward to LB#98 Jeff Smith’s Jeff’s SQL Server Blog on May 23rd. There’s always plenty of room for more editors, so don’t waste another minute — send an email to me, the Log Buffer coordinator, and get started!

Without further ado, here is Mark Schoonover’s Log Buffer #95.
