Canadian Maple Trees, Inc. has a distributed relational database with tables in computers in Halifax, Montreal, Ottawa, Toronto, and Vancouver. The database consists of twelve tables, some of which are replicated in multiple cities. Among them are tables A, B, and C, with the following characteristics.
