"Transaction-based" refers to a system or process that focuses on individual transactions as the primary unit of analysis or operation. In this context, a transaction typically involves an exchange of goods, services, or information between parties, often recorded in a database. This approach is commonly used in fields like finance, retail, and e-commerce, where each transaction is tracked for accuracy and accountability. In a transaction-based model, each interaction is discrete and can be analyzed separately. For example, in a banking system, every deposit or withdrawal is a transaction that can be monitored for trends or anomalies. This method allows organizations to maintain detailed records and improve decision-making based on transaction data.
