Practice Programming Planning Problems using Object Oriented Design– Outline the classes and relationships and describe the programming process for an "automatic meeting scheduler using inputs from a calendar database." Use a simplified version of Unified Modeling Language class diagram. You are not writing the code for this, just the design and the algorithm.
Identify possible objects in the following systems and develop an object-oriented design for them. You may make any reasonable assumptions about the systems when deriving the design.■ A group diary and time management system is intended to support the timetabling of meet-ings and appointments across a group of co-workers. When an appointment is to be made that involves a number of people, the system finds a common slot in each of their diaries and arranges the appointment for that time. If no common slots are available, it interacts with the user to rearrange his or her personal diary to make room for the appointment.■ A filling station (gas station) is to be set up for fully automated operation. Drivers swipe their credit card through a reader connected to the pump; the card is verified by communication with a credit company computer, and a fuel limit is established. The driver may then take the fuel required. When fuel delivery is complete and the pump hose is returned to its…

It does not scale well as your software system grows because it centers around a single entity that does everything.

A movie has a genre (drama, comedy, etc.), a running time, and one director. A movie is made at a movie studio and may have multiple producers (people in charge of the movie production). A movie studio has a unique name and address, and may make one or more movies. Producers are identified by name and date of birth and produce one or more movies.
