All the IT that a small business or a branch office needs

Leon — Fri, 15 Jan 2010 23:50:17 +0000

In the past year we have spent a lot of effort putting DB2 on the cloud and we achieved absolutely fantastic results. Db2 has proven to be a hit on both the Amazon cloud, on RightScale and on the IBM Developer Cloud. But all this focus on running applications on the rented IT infrastructure in the cloud does not mean we don’t care about people who want to have their own IT equipment. The free DB2 Express-C is a good fit for small and medium business and an even better fit for remote offices of very large enterprises. [...]

DB2 Express-C helps Russian ISV improve performance 5-10 times

Leon — Wed, 23 Sep 2009 22:14:32 +0000

If you spend any time in the fast growing Russian IT market there is one name you will no doubt be familiar with. I am not talking about Microsoft, Oracle, HP or even IBM. A company with a very short name “1C” is an icon of the Russian IT economy. Founded in 1991, 1C helped the newly formed Russian companies to get proper accounting and other financial management footing to be able to compete on the local markets and to enter and, in many cases, lead in the global economy. 1C is a major software distributor and an award winning game developer. If [...]

The Article every DBA should forward to SQL developers

Leon — Tue, 08 Sep 2009 18:41:08 +0000

I think that every Database Administrator needs to read the article “Opinion: No more excuses for SQL injection attacks” and send it out to every application developer they know. I hate SPAM as much as the next guy but I think it is justified in this case. I am dead serious. We, the database people of all walks of life (DB2, Oracle, SQL Server …), have been talking about the benefits of using parameters in the queries instead of literal values for years. The main message has been “performance”. Most DBMS will perform much better and will use [...]

Cheap storage just got even cheaper

Leon — Thu, 16 Oct 2008 02:54:10 +0000

When a database person mentions storage, images of cabinets full of disk drives and cables come to mind. But, since in my recent post I promised to talk about cloud computing I figured I’d talk about a different kind of storage. I am talking about storage that you can’t see or touch; I am talking about storage in the cloud. When Amazon (the people that sell us books and CDs) launched their web services AWS, S3 was one of the first services to go online. S3 stands for “Simple Storage Service”. Amazon built out a very significant IT [...]

Free e-book on getting best performance for DB2, SOA environments, and XML applications

Leon — Tue, 16 Sep 2008 04:18:00 +0000

DB2 Express-C comes with XML and Web Services support already backed. There is a free e-book from the experts in all things DB2 that supposedly helps you get the most out of these functions. The author of the section on automatic maintenance and utility throttling, Roger Sanders has written enough books on DB2 to fill a small library. If you ever decide to prepare yourself for a DB2 certification, you will most likely be using one of Roger’s books. Robert Catterall contributed the chapter on SOA performance. Robert has been working with DB2 since the dinosaurs roamed the [...]

Everything you ever wanted to know about a DB2 table but did not know where to look

Leon — Wed, 16 Jul 2008 04:29:52 +0000

Just like any other DBMS, DB2 keeps all of your data in tables. The tables are organized in a usual i.e. data is stored in rows with each row having one or more columns. This is true even in the case when the data that is stored as XML. Hopefully it is not a surprise that DB2 Express-C has a “hybrid” storage engine that stores both relational data and XML data in their native formats. We call DB2′s ability to deal with XML data “pureXML”. For XML, this means that XML documents are stored in DB2 as pre-parsed [...]
