What does a macro in a database do?

• A. It summarizes data presentations
• B. It triggers actions when specific commands are executed
• C. It stores rules for the knowledge base
• D. It defines project goals and functions

Answer: (B)

A macro in a database is designed to automate tasks by triggering specific actions based on certain commands or events. This means that when a user executes a designated command or set of commands, the macro responds accordingly to perform a pre-defined task—such as running queries, generating reports, or modifying data. By creating macros, users can streamline processes, reduce the potential for human error, and improve efficiency when interacting with the database. The other options relate to functionalities that are not specifically executed by a macro. For example, summarizing data presentations involves organizing information in a way that highlights key insights, which is typically done through reports rather than macros. Storing rules for a knowledge base is about maintaining structured information that can aid in decision-making or problem-solving, unrelated to the automation role of macros. Defining project goals and functions pertains to planning and project management activities, which do not directly involve the automation of database tasks as a macro does.
