Unveiled at the company's Partners User Group Conference in Washington, DC, the first device - called Teradata Extreme Performance Appliance - is going onto a customer site in two weeks time. Before you ask, yes, it …

What your database needs is a good thermometer

In the very early days of databases, when they contained relatively small quantities of information, the distinction between frequencies of access was pretty immaterial. Now that we collect and store data in massive quantities, however, the distinction is becoming increasingly important. And apposite terms have evolved to …

In the spin of SSDs on database servers

Interest in solid state drives (SSDs) is growing as their initially terrifying price plummets: Intel recently announced a 60 per-cent reduction in the cost of its X25-M Mainstream SATA SSD since its launch last year. SSDs are attractive because they radiate less heat than traditional spinning disks, they're smaller, quieter …

Sarah Palin's words get data mined

USA '08 Business Intelligence (BI) is about extracting information from data. The name implies that it is only applicable to business information, but that’s misleading. Given the right techniques, information can be found in the most unexpected places - even in the speeches of vice-presidential candidates. Sarah Palin’s meteoric rise …

Beware the innocent systems 'health check'

D'oh! This column has generated a lot of feedback, some indicating that the answers to the problems were obvious. Quite right - they are obvious to people with years of practice, and some of our readers are blessed with that experience. But the whole point of the series is that none of us start with 20 years of experience. We all …

SQL Server 2008 moves on, wants to stay friends

Review Microsoft's SQL Server 2008 is now upon us. More than a year after its initial planned delivery date, Microsoft Wednesday released to manufacturing code for a new version of its database that's almost as significant as its last great release - SQL Server 2005, three years ago. Microsoft is, with SQL Server 2008, bucking its …

Lateral thought saves sizzling server

D'oh! I learned a long time ago that generating random numbers (really, truly random numbers) is a non-trivial exercise. However, I completely failed to apply that computer science lesson to the real world of computing and continued to believe that events in the Newtonian world could happen without a cause. Such a belief system is …

What I learned from a dumb terminal

D'oh! There is a (probably apocryphal) entry in a naval officer's fitness report that reads: "This officer never makes the same mistake twice. However, he appears to be attempting to make them all once." As developers we should try to avoid collecting the full set, but making some mistakes are inevitable; the trick is to learn from …

Windows experiment meets the bottom line

Project Watch: Microsoft 2008 This project I began writing about in late January, the prototyping of a large database project using the latest versions of a Microsoft software stack, has been an unusual exercise. Unusual because, from the start, both the executive and the technical personnel were fully co-operative throughout the entire undertaking. The …

Project Watch: Microsoft 2008 Those who have been following Project Watch will know that I have been leading the development in a large database project using SQL Server 2008, Windows 2008 and Visual Studio 2008. Relatively heavy stuff. Part of that project, though, involves the creation of a mashup that displays our spatial data on a map - yes, I know, all …

Frustration and joy - Microsoft's CTP in action

Project Watch: Microsoft 2008 OK, so choosing and installing the hardware - that was easy. I wish I could say the same for the software. On the face of it all I had to do was install the beta version of Windows Server 2008, the production version of Visual Studio 2008 and the beta SQL Server 2008. Sorry, by beta of course I mean community technology preview …

Windows hardware challenge draws on resources

Project Watch: Microsoft 2008 Here's a question for you: what hardware does it take to run an entirely new, pre-release Windows operating system and 1TB-worth of SQL Server 2008 community technology preview? This question seems simple to answer, but the challenge comes in locating the requisite hardware. One problem that always arises when using any beta …

Back to basics for SQL Server 2008

Project Watch: Microsoft 2008 When I asked: "How do we convert more than 12,000 location items - by hand?" we had almost completed the process as part of our move to Microsoft's up-coming SQL Server 2008. The question was, in fact, rhetorical. Nevertheless, we received a lot of advice and suggestions from Reg Dev readers. This, for example, from …

Experience overcomes Microsoft's broken promises

Project Watch: Microsoft 2008 Before we go on, let's just talk briefly, in a quiet voice, about the delay to SQL Server 2008. The major issue here is that whilst Microsoft conveniently forgets the past, most of us can still remember SQL Server 2003, er...2004, oh, actually, that was eventually 2005. So Microsoft is turning into a serial offender when it …

The 'blem wit' error messages

When I was young I built up a collection of system error messages. Ok, look, it's not as sad as collecting stamps! It is? Really? Oh well, never mind. Anyway, my recent piece about Borland putting rude words in Quattro Pro got me thinking it was time to revisit that collection. Some of them date back to the days of the …

As reported earlier Service Pack 3 for Office takes the unprecedented step of barring access to files created with earlier versions of the product. Install the Service Pack and your stash of …

Why Borland trashed its spreadsheet

Myths and legends Always remember, the compiler is your friend. Programming is stressful but no matter how many f**ks and b***ocks you might occasionally feel the need to insert into the comments, the compiler will always strip them out. It's great. Of course, it doesn't actually go looking for rude words. So it would be a mistake to use them …

Mind your languages with Microsoft LINQ

We've been hearing a growing amount this year about LINQ - Microsoft's Language Integrated Query.

LINQ promises to close the skills and knowledge gap for developers using C# and VisualBasic trying to connect to …

Running queries on the HMRC database fiasco

Comment When it comes to talking about last week's data loss by the HMRC, I was told not to use precious words outlining my feelings of rage and bafflement that a government body can be so cavalier with so much data because, presumably, we all feel the same. So I will simply note, for the record, that my gob has been totally smacked …

Oracle 'cheated' in TPC benchmarks

Myths and legends When database folks gather to sup ale and chat, as they invariably will at Oracle's OpenWorld in San Francisco this week, talk occasionally turns to benchmarking. As soon as it does, someone will say: "Of course the trouble is you can't trust the vendors. Wasn't Oracle caught cheating at the TPC benchmarks?" The public has a …

Evolutionary vs. traditional database design

We recently published an article on the advantages of evolutionary database design (EDBD), a process which has its roots in the agile/extreme programming world.
