What is a Transaction Processing System? Types, Components & Benefits

Transactions of all sorts have become an integral part of the common man’s daily life.

Every business and entity uses a transaction processing system, from a basic grocery store to an online portal.

You see, every exchange you make seems super easy, as all you have to do is make the payment instantly and get your goods. However, that is not what happens in the background.

Every business transaction has a set flow that follows different parameters to fulfill the expected outcome. And all of it happens in a matter of seconds, thanks to modern technology.

Several robust software programs are being used today to ensure that backend processes are flawless.

One such software is the Transaction Processing System. In this post, let us take a closer look at Transaction Processing Systems, what they are, and how they function. We will also be exploring types of TPSs and their components.

What is a Transaction Processing System?

A Transaction Processing System (TPS) is a computer-based system designed to handle an organization’s business transactions. It mainly deals with data-related tasks such as collecting, storing, updating, retrieving, and processing information.

For instance, placing an order, recording the sale, checking, updating, and managing inventories, taking payable accounts, and ensuring the smooth financial operations, are all part of a single transaction.

Now, dedicating human resources to manage all of them is neither feasible nor productive, as completing these steps manually will take a lot of time. This is where Transaction Processing Systems (TPS) come into play.

These are high-speed, secure, and multi-tasking systems that take care of all the aspects involved in a transaction and complete them seamlessly.

A key player in this system is the database that is being used to power the transaction processing system.

Now talking about Online Transaction Processing (OLTP) is also a type of TPS that focuses on managing internet-based transactions, such as online banking or order placements, and enables real-time processing across banking, fintech, and retail industries.

Since there are different tasks that these systems have to perform, they have different components attached to them.

Components of a Transaction Processing System

A well-functioning Transaction Processing System is built based on 4 components. These components take care of different aspects to fulfill the requirements of the users.

Here are the components that make up the entire functionality of the Transaction Processing System- 

♦ Inputs

For every transaction that you need to process, there has to be some information that you feed to the system. This information can be anything from an order, inventory information, or payment details.

Inputs may come in several forms, such as:

• Customer purchase details
• Payment and billing information
• Supplier order entries
• Product return requests
• Customer feedback forms
• Account balance inquiries

♦ Processing

All the information that you feed to the TPS is then processed based on your requirements.

For instance, if the input is related to a customer order, the system will help you calculate the order value along with the required discounts that can be offered. All of it is done instantly.

The system performs a variety of operations to handle transactions efficiently, including:

• Total Order, taxes, and applicable discounts
• Validating customer details and financial transactions
• Updating stock and inventory records in real-time
• Creating invoices, receipts, and billing statements
• Processing returns, refunds, and exchanges
• Applying loyalty points or promotional offers
• Monitoring transaction errors and exceptions

♦ Outputs

Once your input is processed, the transaction processing system (TPS) shows the information generated. It can help you generate invoices, show order status, trigger notifications, and more.

The results of transaction processing can be displayed in multiple ways, including:

• Show transaction history or alerts to the user
• Generating printed or digital invoices, bills, and receipts
• Updating records in customer or financial databases
• Sending SMS or push notifications for transaction status
• Producing reports for management or accounting purposes
• Exporting data to external systems or partners
• Providing confirmation messages via chatbots or web portals

♦ Database

This is the component where all the magic happens. All the transaction information, be it the order value, final order payment, customer information, payment details, and every other detail related to the transaction, is saved.

This helps in automating bulk processes such as payroll, maintaining sales records, etc. All these components work together like a well-oiled machine to bring the best results out of a TPS.

• Supplier information: contact details and order history

• Marketing data: campaign results, customer preferences, and engagement metrics

• Service requests and support tickets: issue details and resolution status

• Loyalty programs: points earned, redemption history, and membership tiers

• Regulatory compliance records: tax filings, audit logs, and certifications

• Inventory movement logs: stock transfers, returns, and adjustments

• Pricing and discount policies: current offers, promotions, and historical changes

When all of these aspects are sorted for a transaction, you can rely on the accuracy and efficiency in data management & operations.

Types of Transaction Processing Systems: Pros & Cons

Knowing how crucial the system is, you might have become curious about what type of solutions are implemented in the form of a TPS.

There are two types of Transaction Processing Systems-

► Real-time Processing
