You may use different design in yourimplementation)Validation should be done for each transaction to avoid logical errors (e.g. prevent negativevalue for the chocolate weight). Application of advanced OOP concepts such as Inheritance,composition & aggregation will gain higher marks in the overall assessment. Project OverviewThe Delicious Chocolate (DC) outlet is located in Penang. The company has various types ofhandmade chocolate and each product item are classified with the product id, name,type/category (e.g. dark chocolate, white chocolate and etc), and the price per 100 grams. Theproduct id could be defined using 2 letters (category code) and 3 digits combination (001). Forexample, the first product id for the white chocolate should define as 'WC001'.The manager wants you to develop a simple catalogue system to help them sell and maintaintheir products effectively. Basically, the menu should have four options namely New Order,View Order Maintenance and Exit. The Order option will allow the user to enter the orderdetails such as order id, order date, item no and the weight of the chocolate.Enter Order ID: S10001Enter Order Date: 12/11/2022Enter Product Code: WC001[White Chocolate Selected]Enter weight (gram): 500[RM 25]Next Item [Y/N]:Upon the ordering transaction, display the order details in the tabular format and save the orderdata to a text file for historical purposes. The user may click on the menu option 2 to view backthe previous order details by entering the Order ID.Date: 12/11/2022Order ID: S10001Item No#WC001DC001TOTALNameWhite ChocolateDark Bitter ChoWeight500300Per 100g Price ($)5.007.0025.0021.0046.00In the maintenance option, the products can be added, deleted and modified and store in thecatalogue object. All the chocolate details should be saved and persisted into a text file (e.g.product.txt).In this assignment, you are required to use a few classes (refer to figure 1.0) and perform basicassociation among the classes. In the order transaction, the Order class should refer to theCatalogue class in order to check the product details such as price and product description.Provide appropriate attributes and methods for all these classes to perform all the operationscorrectly. You are allowed to add in additional classes, operations and attributes in yourimplementation.

An Art Museum needs to keep track of its artwork and exhibitions. The museum has a collection of artwork. Each piece of art has a unique id [ArtID], an artist, year and title. Artwork is categorized by type. There are two types, paintings and sculptures. Paintings have a paintType and style. Sculptures have a material, height and weight. Artwork is frequently shown in exhibitions. Each exhibition has a unique name, startDate, endDate. A listing of the artwork displayed at an exhibition is also retained. Below is an E-R diagram for a database to help the Art Museum.

Granite Sales Company keeps information on employees and the departments that they work in. For each department, the department name, internal mailbox number, and office phone extension are kept. A department can have many assigned employees, and each employee is assigned to only one department. Employees can be salaried employees, hourly employees, or contract employees. All employees are assigned an employee number. This is kept along with the employee’s name and address. For hourly employees, hourly wage and target weekly work hours are stored (e.g. the company may target 40 hours/week for some, 32 hours/week for others, and 20 hours/week for others). Some salaried employees are salespeople that can earn a commission in addition to their base salary. For all salaried employees, the yearly salary amount is recorded in the system. For salespeople, their commission percentage on sales and commission percentage on profit are stored in the system. For example, John is a…

calculate_new_balance Given a starting balance (a number), and a list of transaction tuples, calculate the final balance for an account. Transaction tuples are of the shape ("description", amount, "withdrawal") , or ("description", amount, "deposit"). The last entry in the tuple will be either "withdrawal" or "deposit". Every withdrawal decreases the balance of the account by the specified amount, and every deposit increases the balance. The return value is the new account balance, as a number. (which could be negative) Sample calls should look like: >>> calculate_new_balance(100, [("payday", 20, "deposit"), ("new shoes", 50, "withdrawal"), ("illicit winnings", 200, "deposit")])270>>> calculate_new_balance(100, [])100
