Final answer:
Electronic document management (EDM) systems have two categories: document storage and retrieval, and business event data processing. Document storage and retrieval focuses on organizing, indexing, and searching for electronic documents, while business event data processing involves capturing and processing data related to business events.
Step-by-step explanation:
Electronic document management (EDM) systems are divided into two categories: document storage and retrieval and business event data processing. The first category, document storage and retrieval, focuses on the storage and retrieval of electronic documents. This includes organizing, indexing, and searching for documents within a system. The second category, business event data processing, involves using EDM systems to capture and process data related to business events, such as invoices, purchase orders, and customer information. These systems help automate business processes and improve operational efficiency.
