system
Overview:
A critical step of the project is to design a
modeling and simulation infrastructure to experiment and validate the proposed solutions.
A point of sale of system is a computerized application system used to record sales and handle payments. In the other words to keep track of all transactions in accounts.
A point sale system is a computerized application used to record sales and handle payments. It is typically used in retail store; it includes hardware components such as computer and a bar code scanner and software to run the system. It interfaces to various service applications such as third party tax calculator an inventory control. These systems must be relatively fault tolerant;
i.e., even if remote services are temporarily unavailable they must be of capturing sales and handling at least cash payments .A Pos system must support multiple and varied client side terminals and interfaces such as browser, PDA’s touch screens.

Roll:-The actors who are involved in the whole process.
1.Owner:
He is the person who feed data, starts billing, calculate the sales and records. He will take the
payment of the customer. He has to update the stock and record sales. He has to interface with various service applications, such as third party tax
calculator.
2.Customer:
He has to pay the payment to owner of sales. He has to support multiple and varied client terminals and interface such as browser. PDA’s touch screens. He should receive the bills and the payment.
Use cases:
The steps involved in the whole process are indicated as use cases.
• Bill all the goods.
• Use interface with PDA’s, touch screens and browser.
• Calculate final bill also include inventory control
• Receive payment
• Record sales which include inventory control.

Roll:-Bill the goods: The owner has to bill the goods and
send details, payments to the customer. He has to handle the payment. The customer has to check the bills and goods received.User interface with PDA’s touch screen and
browser:
The customer has to see the goods list in the form of user interface with PDA’s, touch screens andbrowser. He has to seen all this and sends the list to shop.
Calculate the bill: The owner has to calculate final bill
after receiving the payment from the customer including third party tax calculator that are the service charges and charges of transfer of goods.Receive payment: The owner has to receive he
payment. The customer has to send the owner how he will pay the money. He has to submit all the details of bills that goods are taken by him.
Record sales including inventory control: The
owner has to update details.Update stock and cash details: Every time the
owner has to check the stock that has sold and bring he fresh stock .Every time he has to update the stock and cash details for every customer purchase.Classes:
The classes contain attributes and related to them. The main classes classified in this solution are

Retail store: Through the point of sale system the
customer purchase the goods from the owner. In retail shop the owner has to check the details of the
customer and update all the details of the bills. The retail store includes hardware components such as a computer and bar code scanner and software to run the system. He has to calculate the final including third tax calculator. The owner has to update the sock and cash details.

Customer:
The customer has to send details of theproducts of the owner. He has to pay the money immediately after receiving the goods. He has to inform how he as to pay the money to owner. He has to send interface such as PDAs, browser touch screen wit system.
Diagrams:
The diagrams are of two types:
1.Static diagrams
Static diagrams are again divided into four: a) Class Diagram
b) Object Diagram

A diagram is an interaction diagram that emphasizes the time ordering of messages. It consists of set of objects and actor.
o Actors
1. Owner: He has to feed the data. He is the
person who sells the goods. He has to update the cash and the stock details. He has to
receive the payment from the customer.
2. Customer: The customer has to send the
details of the goods to owner in the point of sale system. He has to interface with the
computer. He has to pay the payment in right time.
3.Collaboration Diagram:
A collaboration diagram is an interaction diagram that emphasizes the structural organization of the objects that sends and receive messages. It shows

4.State Chart Diagram:
A state chart diagram shows a state machine
consisting of states, transitions, events and activities. It emphasizes the event ordered behavior of an object,
which is especially useful in modeling reactive systems.
5.Activity Diagram:
An activity diagram shows the flow from activity within a system. It emphasizes the flow of control among objects.
