Final answer:
The term for the integration of various business information systems into a cohesive system is Enterprise resource planning (ERP), which streamlines operations and improves efficiency.
Step-by-step explanation:
The integration of various types of information systems for business applications is often referred to as Enterprise resource planning (ERP). ERP systems help organizations manage and integrate important parts of their businesses. An ERP software system can integrate planning, purchasing, inventory, sales, marketing, finance, human resources, and more.
ERP systems aid in the streamlining of processes across various departments, creating a synergistic workflow that can greatly increase the efficiency of a business. An example would be the merging of accounting and sales departments to allow for real-time visibility of data, streamlining operations and facilitating better decision-making. These systems exemplify the notion of convergence within business practices, integrating separate information systems into a unified whole that functions more effectively than its disparate parts.
