What is Transaction Processing System ?
A Transaction Processing System (TPS) is a computerized system that facilitates the management and processing of business transactions. These transactions can include purchases, sales, payments, and other activities that involve the exchange of goods, services, or information. The primary goal of a TPS is to ensure that transactions are completed accurately, efficiently, and securely.
TPSs are designed to handle large volumes of transactions in real-time or near real-time, making them essential for businesses that deal with high transaction volumes. These systems typically consist of hardware and software components that work together to capture, process, and store transaction data. They often include features such as data validation, transaction logging, and error handling to ensure the integrity and reliability of the transaction processing process.
Transaction Processing Systems play a crucial role in modern businesses by automating and streamlining the process of handling transactions. They help organizations improve efficiency, reduce costs, and provide better service to customers by ensuring that transactions are processed quickly, accurately, and securely.
Definition of Transaction Processing System
Here are definitions of TPS from various authors:
• James A. O'Brien defines TPS as "an organized collection of people, procedures, databases, hardware, and software to record completed business transactions."
• Kenneth C. Laudon and Jane P. Laudon describe TPS as "computerized systems that perform and record the daily routine transactions necessary to conduct the business."
• Effy Oz defines transaction processing system as "a computerized system that performs and records the daily routine transactions necessary to conduct business, such as sales order entry, hotel reservations, payroll, employee record keeping, and shipping."
• Robert G. Murdick, Joel E. Ross, and James R. Claggett define TPS as "a computerized method of collecting, storing, processing, retrieving, and displaying transaction data for the primary purpose of conducting business."
• Andrew S. Tanenbaum and Albert S. Woodhull define TPS as "a computer system that processes user requests for transactions."
Features of transaction processing system
TPS typically incorporate various characteristics to ensure efficient and reliable processing of transactions. Here are some common features and steps of transaction processing system:
1) Data Capture: TPSs capture transaction data from various sources, such as point-of-sale terminals, online forms, or sensors. This data may include details like transaction amount, date and time, customer information, and transaction type.
2) Data Validation: Before processing transactions, TPSs validate the data to ensure accuracy and integrity. This includes checking for completeness, consistency, and conformity to predefined rules or standards. Invalid or incomplete transactions may be rejected or flagged for manual review.
3) Transaction Processing: TPSs execute transactions according to predefined business logic or rules. This involves updating databases, generating transaction records, and performing necessary calculations or adjustments. Depending on the type of transaction, processing may occur in real-time or batch mode.
4) Concurrency Control: In multi-user environments, TPSs employ concurrency control mechanisms to manage simultaneous access to shared resources, such as databases. This prevents conflicts and ensures data consistency by enforcing rules like locking or timestamp ordering.
5) Transaction Logging: TPSs maintain transaction logs to record details of each transaction, including before and after states of affected data. Transaction logs serve as an audit trail for troubleshooting, recovery, and compliance purposes, enabling organizations to trace the history of transactions and identify anomalies or errors.
6) Error Handling: TPSs include error handling mechanisms to detect and handle exceptions or failures during transaction processing. This may involve automatic recovery procedures, such as retrying failed transactions, rolling back incomplete transactions, or alerting administrators for manual intervention.
7) Scalability: TPSs are designed to scale horizontally or vertically to accommodate growing transaction volumes or user loads. This may involve deploying additional hardware resources, optimizing software performance, or implementing distributed architectures to handle increased demand without sacrificing performance or reliability.
8) Security: TPSs implement security measures to protect transaction data from unauthorized access, manipulation, or disclosure. This includes encryption, access controls, authentication mechanisms, and audit trails to enforce data privacy and compliance with regulatory requirements.
9) Performance Monitoring: TPSs monitor performance metrics, such as transaction throughput, response times, and resource utilization, to ensure optimal system performance and identify potential bottlenecks or performance issues. Monitoring tools and dashboards provide insights for proactive maintenance and optimization.
10) Reporting and Analytics: TPSs support reporting and analytics features to analyze transaction data, generate reports, and derive insights for decision-making and business intelligence purposes. This includes tools for ad-hoc querying, data visualization, and trend analysis to identify patterns, anomalies, and opportunities for optimization.
Types of Transaction Processing System
Transaction Processing Systems (TPS) can be categorized into several types based on their functionality and the nature of transactions they handle. Here are some common types:
1) Batch Processing Systems: These systems process transactions in batches, collecting a set of transactions over a period and then processing them all at once. Batch processing is suitable for tasks that don't require immediate processing, such as payroll processing or billing.
2) Real-time Processing Systems: In contrast to batch processing, real-time processing systems handle transactions as they occur, providing immediate feedback or response. These systems are crucial in environments where instant processing is necessary, such as online banking or stock trading platforms.
3) Online Transaction Processing (OLTP) Systems: OLTP systems are designed to manage and process a large number of short online transactions. They are optimized for high throughput and low latency, making them suitable for applications like order processing, inventory management, and customer relationship management (CRM) systems.
4) Distributed Transaction Processing Systems: These systems distribute transaction processing across multiple nodes or servers, allowing for scalability and fault tolerance. Distributed TPSs are common in large-scale enterprise applications and cloud computing environments.
5) Mobile Transaction Processing Systems: With the proliferation of mobile devices, there's a growing need for transaction processing systems tailored for mobile platforms. These systems enable users to perform transactions using mobile apps or web browsers, such as mobile banking apps or e-commerce platforms.
6) Point-of-Sale (POS) Systems: POS systems are specialized TPSs used in retail and hospitality industries to process sales transactions at the point of purchase. They typically include hardware components like cash registers, barcode scanners, and card readers, along with software for inventory management and sales reporting.
7) Financial Transaction Processing Systems: Financial TPSs are specifically designed to handle financial transactions, such as fund transfers, payments, and securities trading. These systems must adhere to strict security and regulatory standards to ensure the integrity and confidentiality of financial data.
