The process approach to information systems evolution. Retrospective indexing

Inspired by the ideas worked out ISO9000 process approach to IS architecture for scaled collaborative creative activity support. The approach is based on direct access to retrospective information, separated data writing and functional-reactive performance. Giving users the ability to time travel and the organization of parallel worlds, it promises high reactivity, the constant availability, increased fault tolerance and tolerance to unexpected overloads, breakdowns and sudden rearrangements of the system. The future system architechture and detailed retrospective indexing algorithm are under consideration.
