Doing Enterprise Architecture, Part 2: Thinking Really Big

by Ken Orr

When people ask me when I first became interested in enterprise architecture (EA), I tell them that I've always been interested in really large systems problems, but it was probably when I first began to work on Data Warehousing that I came to understand the essence of EA. My reading of data warehousing history is that the discipline goes back to some IBMers working in Europe in the early/mid-1980s. At that time, relational databases were becoming all the vogue and a group of people centered around Barry Devlin in Dublin were given the job of coming up with a plan to convert all of IBM's business intelligence applications from whatever databases they existed in to DB2. This turned out to be a really big order. In fact, as the group laid out the plan, it became clear that by the time they had converted everything, IBM would be at DB8!
