Transaction processing systems are fundamental to business operations as they support the essential activities involved in designing, marketing, producing, and delivering products. By automating these core processes, these systems ensure that functional units—such as sales, production, finance, and human resources—operate cohesively.1

In larger organizations, these functions are often managed through integrated enterprise systems, such as:

Enterprise Resource Planning (ERP): Supports the entire value chain, allowing for automated workflows like just-in-time production based on custom customer orders, while simultaneously updating financial accounts and logistics.1
Supply Chain Management (SCM): Integrates the broader supply chain by managing the flow of products, data, and money from raw material suppliers to final retailers. This enables automated restocking and efficient inventory management via shared databases.1
Customer Relationship Management (CRM): Provides a unified view of customer interactions, fostering consistent relationships and enabling customer involvement in product development.1

Furthermore, these systems facilitate electronic commerce over the Internet and accumulate the critical data necessary for higher-level organizational decision-making.1
