I had a day off work today so I could go over to Birmingham City University (BCU) and do a talk to the students.
Today’s session was more about giving them an idea of where databases fit into the big picture as far as data and data processing is concerned. I obviously come at this as a relational database guy, but the presentation also included NoSQL and Hadoop. I hope nobody is naive enough anymore to think relational databases are the correct solution for every use case, so it’s important to be objective about this stuff, rather than to push your own agenda.
Over recent weeks I’ve spent time trawling through material to get a feel for the subject matter, and it’s quite depressing to see the territorial pissing that goes on between all these camps. Each trying to convince you their solution is suitable for use cases where it clearly is not. To be fair, most of this is not coming from the experts themselves, but from the hangers on who can’t cope with the fact their favourite tech might not be perfect. We’ve all been there!
