Final answer:
A functional business system supports transaction processing, management information, and decision support, but not typically email communication, which is usually managed by dedicated communication applications.
Step-by-step explanation:
A functional business system is designed to integrate various automated processes within an organization to ensure smooth operations. These systems support a wide range of activities that are crucial for the daily functions of a business, including:
- Transaction processing—recording and processing of the data generated from business transactions.
- Management information—compilation of data from various sources to produce reports for management.
- Decision support—providing information and analytical tools to help with managerial decision making.
However, a functional business system does not typically extend to personal communication tools such as email communication. Email communication is typically handled by separate applications dedicated to personal or interoffice communication rather than being an integrated function of a business system designed for transaction processing, management reporting, and decision support.
