To be irritatingly precise: the number of users is limited to the positive range of an SQL INTEGER, which is implementation dependent. PostgreSQL defines INTEGER to be a 32-bit signed binary value, so a single instance of DSpace can register a maximum of 2147483647 users, or about one fourth of the present population of Earth. Groups are separately limited to the same range. In practical terms, an instance of DSpace is unlikely to ever hit these limits. Oracle defines INTEGER as NUMBER(38) (at least large enough for a 38-digit decimal number), which is somewhat larger. Probably DSpace's Oracle table definitions should use BINARY_INTEGER to match both PostgreSQL and common expectations, but they don't. -- Mark H.
