1. A method for operating a computer arrangement for a scalable network of computers to interact with certain information stored in a group of networked databases, at least some of which having different schema, comprising: each one of the networked computer using a standardized database access system storing a group of stored standardized algorithms to enable data to be accessed in a standardized manner from all of the networked databases; determining the validity of the data provided by means of the algorithms in the standardized data access systems by using at least one validity management module in each one of the computers, and if the data provided by means of the algorithms is determined to be invalid by a validity management module in one of the computers, updating the algorithm providing the invalid data or updating the invalid data to thereby correct the invalidity; whereby self corrections occur dynamically over time with changing stored information.
