Step-by-step explanation:
An information system that supports business functions such as accounting, finance, human resource management, marketing, or operations can be classified as an Enterprise Resource Planning (ERP) system. ERP systems integrate various functional areas of an organization to provide streamlined and efficient workflows, facilitating the sharing and updating of data across different departments. These systems often include human software interactions, aiding decision-making processes for employees who utilize the system.
While other systems like Decision Support Systems (DSS), Transaction Processing Systems (TPS), and Executive Information Systems (EIS) may also play roles in an organization, ERP uniquely covers a broad range of functionalities tailored to support and manage multiple business processes comprehensively. ERP systems are part of the basic support systems that are needed to keep an economy's infrastructure such as power, communications, transportation, water, sanitation, and education systems operating efficiently.
