Ever wondered how DB2 and Informix Dynamic Server architectures compare? Which major features they have in common and what separates them? What are the major editions and platform support between the two? These questions and more are answered in a new developerWorks article by Suma C Shastry, Mohan Kumar, Prasad Srinivasachar entitled How to go hand-in-hand with DB2 and Informix.
It looks like this article has been well-researched. Particularly interesting to me are the architecture diagrams, which include Architecture overview, Process Model, Memory model, Instance Architecture, Backup mechanisms, Security architecture, administration tools.
