What type of system focuses on internal business managerial needs and deals with high volume data input?

The correct choice is a Management Information System (MIS), which is specifically designed to cater to the internal managerial needs of an organization. An MIS facilitates the effective collection, processing, and presentation of data to support managerial decision-making.

Management Information Systems typically handle large volumes of data input from various sources within the organization and transform this data into valuable information through reports and dashboards. This enables managers to monitor operations, track performance metrics, and make informed decisions based on accurate and timely data. The emphasis is on providing structured information that helps in routine management functions and operational oversight.

Unlike other systems, an MIS is structured to support the day-to-day operations and management process rather than providing analytical capabilities for scenario planning or strategic decision-making that would be found in Decision Support Systems. It is also distinct from Transaction Processing Systems, which primarily focus on capturing and processing transaction data rather than generating comprehensive reports for management.
