Method of partitioning a database

A method of accessing partitioned data in a database, the method comprising:

• receiving a request for access to particular data within the database from an entity;
• determining whether the data is assigned to a first partition;
• determining whether the data is assigned to a second partition;
• determining whether the entity is assigned to a first partition;
• and
• determining whether the entity is assigned to a second partition;
• if the data is assigned to a first partition and a second partition, conditionally granting the entity access to the data if the first partition assigned to the data matches a first partition assigned to the entity and the second partition assigned to the data matches a second partition assigned to the entity.

A method of accessing partitioned data in a database comprising:

• receiving a request for access to the database from an entity, the request comprising an entity reference;
• determining whether the entity is assigned to any partitions of the database based on the entity reference;
• and
• filtering the data within the database so that data assigned to a first partition and a second partition may only be accessed by an entity assigned to said first partition and said second partition.

A data structure for partitioning data within a database comprising:

• one or more data tables comprising one or more entries, each entry comprising a set of data;
• and
• for each entry in said one or more data tables:
• a first partition parameter for assigning the set of data to a first partition;
• a second partition parameter for assigning the set of data to a second partition.
