A scalable computer arrangement and method accesses certain stored information using algorithms. The validity of the algorithms and retrieved data are determined by validity management modules. If the algorithm or the retrieved data is determined to be invalid, the algorithm or retrieved data may be updated to self-correct dynamically over time with changing stored information. In another embodiment, the computer arrangement includes standardized database access systems having hyper objects for accessing information across the network in a standardized manner, even though the networked databases may employ different schema and formats. Each computer system operates independently, and yet is able to dynamically self correct when invalid algorithms or data is determined. New computer systems can be added or removed without requiring adjustments to its database schema or formats and without synchronizing with the existing networked computer systems.
