Question: Investigate any client/server system that might be available to you. Does that system support explicit CONNECT and DISCONNECT operations? Does it support SET CONNECTION or any other "connection-type" operations? Does it support multi-server transactions? Does it sup-port two-phase commit? What formats and protocols does it use for client/server communication? What network environments does it support? What client and server hardware platforms does it support? What software platforms (operating systems, DBMSs) does it support?
