Abstract: According to at least one embodiment, a method, a computer system, and a computer program product for minimizing I/O operations when validating databases are provided. The present invention may include creating a corresponding system-managed chain database for an application database, the chain database comprising a list of one or more dynamically allocated records, if present, for one or more fixed entries in the application database, wherein each of the fixed entries comprises a respective chain database array item in the chain database; scanning, via a validation utility, one or more chain database array items; marking each of the one or more dynamically allocated records listed in the chain database for the fixed entries as found; and checking, via an indicator with various states, if the one or more dynamically allocated records for the one or more fixed entries are listed in the respective chain database array item.

Abstract: A computer-implemented method for storing documents in a centralized database system based on geographical data localization includes receiving, by a database manager, a request to update a document according to a data localization criterion, the document stored in a local storage device of the centralized database system. The method further includes determining, by the database manager, a geographical location for a local copy of the document based on an attribute of the document matching the localization criterion. The method further includes creating, by the database manager, a remote copy of the document on a storage device that is physically located in the geographical location. The method further includes modifying, by the database manager, the local copy of the document to include a location information of the remote copy.
