A customer has a unique name, an address, and a category (an integer number from 1-10). A customer can order several assemblies. Each assembly is identified by a unique assembly-id, and has a date-ordered, and assembly-details. To manufacture assemblies, the organization contains a number of processes, each of which is identified by a unique process-id and is supervised by one department. Each department has its own department number and department-data. Each process also has process-data. Processes are classified into three types: paint, fit, and cut. The following information is kept about each type of process: Fit: fit-type Paint: paint-type, painting-method • Cut: cutting-type, machine-type During manufacture an assembly can pass through any sequence of processes in any order; it may pass through…An art museum owns a large volume of works of art. Each work of art is described by an item code (identifier), title, type, and size; size is further composed of height, width, and weight.

An artist is described by an artist ID (identifier), name, date of birth, and date of death (which is null for still living artists). Only data about artists for works currently owned by the museum are kept in the database. At any point in time, a work of art is either on display at the museum, held in storage, away from the museum as part of a traveling show, or on loan to another gallery. If on display at the museum, a work of art is also described by its location within the museum. A traveling show is described by a show ID (identifier), the city in which the show is currently appearing, and the start and end dates of the show. Many of the museum works may be part of a given show, and onlyactive shows with at least…
