All the thoughts of men, women and children are mere reflections of gods thoughts - to use an analogy. What we have been doing for thousands of years has been to a greater or lesser extent IM and KM, we've just been really really bad at it. We've taken the cavalier attitude to knowledge and information in most aspects of life, learning and culture. Computers and IT just allowed us to keep on doing the same thing, only quicker, higher and more of it. It may well be true that KM does not specifically drive the creation of databases, personally I would tend to take the position that with the misuse and abuse of database methods and technologies in the past, there will be a reassessment of how to use repackaged technologies to handle the slightly more complex data structures - and yes, as we all know, you can store a document, or a video clip or whatever in a relational database.
Tools are tangible.
Information and knowledge are not. Hardware, software and consulting companies need to constantly generate revenue. KM is an attractive value proposition. These information assets may include databases, documents, policies and procedures as well as the uncaptured, tacit expertise and experience resident in individual workers.
