What are the characteristics of transaction processing systems?

Transaction processing systems (TPS) are designed to handle a large volume of routine, repetitive transactions efficiently and accurately. Key characteristics include reliability, ensuring data integrity through ACID (Atomicity, Consistency, Isolation, Durability) properties, and real-time processing capabilities. TPS typically feature user-friendly interfaces for data entry, support for concurrent transactions, and robust security measures to protect sensitive information. Additionally, they provide detailed audit trails for transaction history and accountability.
