Abstract

Method and system for providing selective access to different portions of a database by different subgroups of database users. Where N users are involved, up to 2N−1 distinguishable access subgroups in a group space can be formed, where no two access subgroups have the same members. Two or more members of a given access subgroup can edit, substantially simultaneously, a document accessible to each member.
