Q & A

What is the main objective of object-oriented system analysis and design in the context of the video rental store?

The main objective is to develop a structured system that is organized, reusable, and flexible, allowing the video rental store to manage inventory, customer registrations, and rentals efficiently using object-oriented principles.

How does the store manage its inventory of movies and games?

The store manages its inventory by categorizing movies and games, tracking stock quantities, and allowing employees to search items by title. Popular items are kept in multiple copies to ensure availability.

What role do employees play in the system?

Employees can add items to the inventory, register customers, check customer rental histories, and process rentals. They are also responsible for ensuring customers return rented items on time.

What criteria must customers meet in order to rent items from the store?

Customers must be registered in the system before they can rent items. Only customers with a valid registration can borrow movies or games.

What happens when a customer rents an item?

When a customer rents an item, the employee records the rental details, including the item and customer information. The rental duration is set, and the customer must return the item within 3 days.

What system features are available for employees to track rentals?

Employees can track which customers have rented items, how many times they have rented, and ensure the items are returned on time. They can also check overdue rentals and fine customers accordingly.

How does the return policy work for rented items?

Customers must return rented items within 3 days of the rental. If items are not returned on time, the system tracks the overdue status and employees can apply fines.

What types of items can be rented from the store?

The store offers movies (including 4D movies) and games for rent. Items are categorized by type and popularity, with more popular titles being available in larger quantities.

How does the system handle the return of rented items?

Employees verify the return of items, update the stock count, and close the rental transaction. They also check whether any fines are due for late returns.

How does the object-oriented design apply to the video rental system?

The system uses object-oriented principles such as classes, inheritance, and methods. For example, movies and games are subclasses of a general 'Item' class, allowing shared behaviors and individual differences. This makes the system modular, easier to maintain, and scalable.
