Thanks Phil, I thought the comparison to the Patriots was overblown. The Patriots wanted to freedom from a tyrannical system that was improper under any condition. The NoSQL crowd just seem to be in a situation that doesn't require all that RDBMSs offer.

Noel,

Yes, I had to calm down a bit before writing the editorial. The comparison was, I thought, impertinent. The trouble is it does a great disservice to the NoSQL group, who seem to be a genuine special interest group with some interesting ideas for open-source BASE systems. It doesn't pose any threat to SQL RDBMSs at all as far as I can see from their presentations. A few wild men have rallied to their flag, but I suspect they'll soon drift off to the next 'big thing' in OODBMSs. Then, I reckon we could get some interesting ideas being generated from the group.


Best wishes,

Great post Phil.

It inspired a blog post (http://sqlblog.com/blogs/andy_leonard/archive/2009/07/11/art-vs-science.aspx).

Relational databases were meant for structured data and not unstructured data as used by the BASE systems. Using a wrong tool to do the job is not the tools limitation

Back in the days before PCs, when I worked as a Systems Analyst on IBM Mainframes you had the choice of storing your data either in a hierarchical database (IMS/DL1) or on the new-fangled relational DMBS (DB2/SQL).

If your data model was heirarchical, you didn't attempt to implement it on DB2, conversely if the data model was relational, you didn't use IMS...

30 years later we seem to have lost sight of the fact that not *all* data models are relational.

A logical data model is a logical one. It can be implemented in a relational, network, hierarchical or object-oriented database. Go to bottom of page here for one assessment of advantages of each: http://www.cs.pitt.edu/~chang/156/20dbdesign.html

It's a matter of appropriate tool for the job... sometimes you need a hammer, sometimes a nail gun.

I remember one user who had a small (3000 name) ad hoc, lightly used mailing list in Excel. Well meaning people had told her to 'upgrade' to SQL Server, and I advised her just the opposite. Excel did the job, she could understand the model... no need to over complicate.

The issue boils down to: how stand-alone is the application? If it's totally stand-alone, then the data implementation can be solely for the convenience of the app designer (or user if it's in Excel). But those apps are few and far between: most companies want to see reports, gauge effectiveness, share a customer master and a product master and to measure ROI. Stand-alone apps are rarely designed for that "enterprise vantage."

If the data is a shared resource, then it's an enterprise resource and needs to be managed and designed as such.

It's like the difference between a go-kart and a Hummer. The go-kart is lots easier to build, and may have some specialized military usage. But the Hummer is the better choice for most battles.

Is somebody keeping track of the individuals, projects and companies who're buying into this? I'm going to be on vacation this week and there's not much good on during summer daytime TV. Should be fun to watch... I'll go make some popcorn. Hehe
