摘要：
The invention relates to a client computer (10) for querying a database stored on a server (22) via a network (48), the server (22) being coupled to the client computer (10) via the network (48), wherein the database comprises a set of first relations (32; 34; 36), wherein each first relation (32; 34; 36) in the set of the first relations (32; 34; 36) comprises first data items, wherein for each first relation (32; 34; 36) the first data items are encrypted with a respective first cryptographic key (18) in the first relation, wherein the first data items form a partially ordered set in each first relation, in each first relation (32; 34; 36) the partial order being formed with respect to the first data items of said first relation (32; 34; 36) in non-encrypted form.
