Title: Service Orientated Architecture to scale to infinity and beyond or Service Orientated Architecture for robust and scalable systems

Proposal: Software Architecture is hard. And when your business grow, its getting even harder because scaling doesn’t come out the box and it’s not only the software which grows it’s also the team. So you have to find a way how to scale your software in a way that it stays easy maintainable for growing teams and scalable. I’d like to talk about Service Orientated Architecture in general and also share some experience and give some examples where SOA would save your ass and maybe places where SOA isn’t the best idea to implement.

What’s new in Apache CouchDB 0.11 — Part Two: Views; JOINs Redux, Raw Collation for Speed

Hi again! It’s Jan again. Thanks for coming back. If you missed Part One, here’s your chance to catch up.

CouchDB JOINs Redux

When I started out talking about CouchDB (back in 2006) people were rarely aware of any databases that didn’t use SQL for querying. An frequent question was “How do I do JOINs?” — The short answer is “You don’t”. People worried about retrieving “related data” from a non-relational database.

Turns out “related data” and “relation” have very little in common (the first is groups of data, the second is a mathematical term that refers to a multivalued mapping more commonly called a “table” ). Long story short there was (and still is) confusion.
