Abstract: In a relational database management system (RDBMS), a method of processing related records can include receiving a plurality of related records and inserting the plurality of related records into a single table of an RDBMS. The plurality of related records can be associated as a set within the single table using a published function of the RDBMS. Responsive to a triggering condition, particular related records of the set can be selectively purged from the single table.

Abstract: Secure storage of sensitive data sets in virtually insecure storage facilities is accomplished presently by storing small granular portions of the data (e.g. bits or bytes) in a randomly dispersed manner. The data sets contain information which requires secure handling. However, the granular portions are sufficiently small to ensure that they do not per se reveal any sensitive information, and they are so dispersed in storage that the probability of unauthorized access to useful information in any data set is extremely small. As an example of sensitive data subject to handling as presently contemplated, consider information pertaining to credit card accounts including cardholder, names and addresses associated with account numbers and cardholder identifying information such as social security numbers, etc. The present selection and dispersal of granular portions of this data effectively co-mingles portions of different data sets in storage in a random manner.
