Title: Access to a partitioned database
Inventor: THURINGER JOHN NEIL
IPC: G06F17/30
Filed: 2009-04-30
Abstract: A partitioned database is configured to be accessed by an entity, such as a regional business unit user, may only access data if they are part of both or all relevant partitions. First and second partitions within the database are defined and selected data in the database assigned to the first partition and the second partition. The system may be used for business units across different jurisdictions to access regulated data such as social security numbers, where they are members of both appropriate groups, such as allowed country, and allowed business unit. Data may be assigned to no partitions, solely one partition or to both partitions. Data assigned to no partition may be permitted to be accessed by all users. The assignments may be achieved by adding columns to a data table each denoting a different partition to which the data is assigned. The partitions may represent organizations, regions, legal groups or legal entities, who can then only access filtered data.
