Transaction Information System Used By MacDonald.

Information system

An information system (IS) collects, processes, stores, analyzes, and disseminates information for a specific purpose.

An information system includes inputs (data, instructions) and outputs (reports, calculations).

It processes the inputs and produces outputs that are sent to users or to other systems via electronic networks and a feedback mechanism that controls the operation.

Types of Information Systems: There are basically Five types of information systems.

• Transaction Processing System• Office Information System• Decision Support System• Management Information System• Expert System

Office Information System: Uses hardware, software and Networks to enhance workflow & facilitate communications among the employees.

Transaction Processing System: The information system that captures and processes the data generated during an organization's day-day transactions

Management Information System: An Information system that generates accurate, timely and organized information so managers & other users can make decisions, solve problems

Decision Support System: An information System designed to help users reach a decision when the decision making situation arises

Expert Systems: The information system that captures & stores the knowledge of human experts & then imitates human reasoning & decision making process for those who have less expertise.

Types of information systems That are used in McDonalds are:ᵜ Transaction Processing Systemᵜ Management Information systemᵜ Decision Support Systemᵜ Made for You systemᵜ Hyperactive bob systemᵜ Point of sale Systemᵜ Touch Interface Operating System

Transaction Processing System

Case Study Transation Processing System

What is TPS???

Definition:

A Transaction Processing System (TPS) is a type of information system that collects, stores, modifies and retrieves the data transactions of an enterprise.

.

The success of commercial enterprises depends on the reliable processing of transactions to ensure that customer orders are met on time. The field of transaction processing, therefore, has become a vital part of effective business management

Transaction Processing System (TPS)

Ttransaction - happens when two people make an exchange

Collecting data about it is called transaction processing

So transaction processing is collecting, storing, modifying, and retrieving the transactions of an organization.

Transaction system helps to conduct business such as payroll, employee record keeping or paying an employee.

It's important to store the data of the transaction save and protected

Features of Transaction Processing Systems

• Rapid response – fast performance with rapid results• Reliability – well designed backup and recovery with a low

failure rate• Inflexibility – treat every transaction equally. It may be used

many times each day which means it has to be precise and inflexible

• Controlled processing – maintain specific requirements for the roles and responsibilities of different employees.

Qualifiers

Atomicity - A transaction’s changes to the state are atomic: either all happen or none happen. These changes include database changes, messages, and actions on transducers.

Consistency - TPS systems exist within a set of operating rules (or integrity constraints). The actions taken as a group do not violate any of the integrity constraints associated with the state.

Isolation - Even though transactions execute concurrently, it appears to each transaction T, that others executed either before T or after T, but not both.

Durability - Once a transaction completes successfully (commits), its changes to the state survive failures.

Hardware Architecture

How Transaction Processing System is implementing in McDonalds?

McDonalds everyday sells a huge amount of hamburgersMcDonalds should order raw material from its supplier each time McDonalds place an order with its supplier , a transaction happens , and the transaction processing system records the relevant information such as supplier ‘name , address , the quality of the items purchased and finally the invoice amount.
