Chapter 2 Overview Of Transaction Processing and ERP Systems

This assignment involves reviewing key concepts related to transaction processing systems and enterprise resource planning (ERP) systems. It covers data processing cycles, types of data input and storage, advantages and disadvantages of ERP systems, and fundamental activities such as data creation, reading, updating, and deleting. The task also requires understanding different output formats and the implications of ERP implementation, including integration, management visibility, and organizational changes.

Transaction processing systems (TPS) and enterprise resource planning (ERP) systems are core components of modern business information systems that facilitate efficient data management and organizational integration. Understanding their structure, functions, and benefits is essential for grasping how organizations operate and respond to information needs in a dynamic business environment.

The data processing cycle is fundamental to understanding how transaction data are collected, organized, and stored within an organization. It determines what data is stored, who has access, and how unanticipated information needs are met. This cycle involves several key steps: data input, processing, storage, and output. During data input, organizations capture information at the point of activity, whether via paper-based source documents like sales forms or automated sources such as ATMs or POS terminals. Well-designed source documents—like prenumbered forms—help ensure accuracy, control, and consistency, supporting the internal control environment.

Data storage within an AIS utilizes various forms, including paper-based ledgers and journals, as well as computer-based systems such as databases. Ledgers provide summary-level data for assets, liabilities, equity, revenues, and expenses, while subsidiary ledgers detail specific accounts like accounts receivable and payable. Journals record specific transactions, either general or specialized, depending on frequency and nature. Computer storage organizes data into entities, attributes, fields, records, and files, enabling efficient retrieval and manipulation of data. Types of data files include transaction files—containing records for specific periods—and master files, which maintain permanent organizational data that are updated through transactions.

The core activities in data processing encompass creating new records, reading existing ones, updating data, and deleting records as necessary. Outputs from these processes are delivered as soft copies—displayed on screens—or hard copies printed on paper, depending on user needs. The integration of data through ERP systems allows organizations to have a unified view of operations, capturing data once and improving management visibility, monitoring, and decision-making. ERP systems standardize procedures across departments, enhance customer service, and streamline manufacturing processes, but they also present challenges such as high costs, lengthy implementations, organizational disruptions, and resistance to change.

Implementing ERP systems signifies a strategic shift that impacts organizational structure, business processes, and employee roles. Despite the initial hurdles, the long-term benefits—improved data accuracy, operational efficiency, and competitive advantage—often justify the investment. Overall, understanding the data cycle, storage solutions, and ERP advantages and disadvantages provides essential insights into how modern organizations leverage technology for operational success.
