What is Information Systems ?In these days, Information systems used in every field of life
For example: Education, Manufacturing, Researches, Games, Entertainment, Business and etc.
So it is define as :
An Information System is a combination of software, hardware, and telecommunication systems which can support business operation to increase productivity and the help managers make decision. 0R
Information system: system consisting of the network of all communication channels used within an organizati
Many companies today use IS as a basis productivity, producing quality products, providing quality services , creating customer confidence and making timely decision.
Components of IS
Information System contains 5 components

Transaction Processing System A transaction processing system (TPS) is an
information system that captures and processes data generated during an organization’s day-to-day transactions. A transaction is a business activity such as a deposit, payment, order or reservation.
0R
Transaction Processing Systems (TPS) System that performs or records daily routine transactions .
0R
Transaction Processing Systems (TPS) System that collects, stores, modifies, and retrieves the data transaction of an enterprise.
Examples of TPS
There are different examples of Transaction Processing Systems (TPS)
Paying by cheque
Credit &Debit card
E-Commerc
e
MICR
Barcode Reader
Payroll
Sales order Entry
ATM
Batch Processing
Batch processing transaction is the processing as collects the data/ store at a time of the event with actual updating of the database later when it is schedule or there is enough data.
An example may be accounts which are make to be easily stored & update due to amount and type of data. Example of this maybe telephone
Real-Time Processing
Real time Processing is the processing as real time transaction processing as immediate processing of data with the database update as the transaction is being carried out.
An example maybe ATM or POS terminal.
Both have user input which require feedback.
Batch processing vs Real time processing
Batch processing Real time processing
transaction data are accumulated
processed periodically used to be necessary
because of synchronization problems
Example is paying by cheque
also called online immediately processed Syncronization issues What if two people order
the same product at the same extact time, but there is only one product left
Example of real time processing is ATM
Feature of transaction processing system
Rapid response:
Fast performance with rapid result. Reliability:
Well designed backup and recovery with a low failure rate.
Inflexibility:
Treat every transaction equally. It maybe used many time each day which means it ha to be precise and inflexible
Controlled Processing:
Maintain specific requirement for the roles and the responsibility of different employees.
Qualifiers for TPS
In order to qualify as a TPS transaction made by system must pass by the ACID test
Atomicity Consistency Isolation Durability
STAGES OF TRANSACTION PROCESSING
Five Stages Of Transaction Processing Data Entry Processing Database Maintenance Document And Report Generation Inquiry Processing
Processing cycle
Data Entry Transaction Processing
Collecting and capturing transactions
No longer manual: Old technologies Bar
Codes, Magnetic Strips (credit cards)
New technologies RFID, Smart Cards,
Synchronization Issues: Which transaction to
process next.
Breaking ties
Dependencies○ Can’t schedule delivery
before credit approval.
Processing Cycle
Database Maintenance Document/Report Generation
TPS helps ensure the databases are up-to-date and correct.
Multiple databases A single purchase
decreases quantity – Inventory Database
decrease credit – Credit Card Database
sales – Sales Database
Document/Report Generation
Examples purchase orders pay checks sales receipts invoices bank statements
An MIS also generates reports, but TPS reports are operational (no analysis).
Inquiry Processing
Examples when was a purchase made does a customer have any credits on their
account was an item scheduled for delivery was a package signed for
An MIS also allows for inquiries, but the information available is summarized (or aggregated), i.e., What are the total sales for a whole department? What is the best selling product?
Summery Every organisation needs to be aware and conscious of development, especially in the fields of computing and information technology, to ensure that they would not be left behind and fail in the competition to move forward. • To compete in business, the management needs to provide the necessary infrastructure so that the information technology environment can be developed. This includes the provision of the information system components. • To realise information systems in business, an information system expert needs to model a business process, i.e. to determine what are the business activities for an organisation, and what are the processes involved in the implementation activity. With this kind of specification, a new information system can be developed. • Information systems play a very important role in the management aspect of an organisation. By looking at the functions and the scope of its use, an information system can be divided into two main support systems, i.e. Operation Support System and Management Support System.
