Answer to Question 1

FALSE

Answer to Question 2

A transaction database is optimized to handle as many transactions as necessary in real time. That means its primary concern is processing speed. A management information system is optimized for running queries and creating summaries that are useful to business managers. A management information system does not have to be as fast as a transaction database. Often the management information system uses the data copied from a transaction database, since the reports typically don't have to be accurate to the current moment.
