Solution

The benefits of a database include:

  1. Databases enforce standards relating to data quality: This is true. Databases have mechanisms to ensure the consistency, accuracy, and integrity of data. They enforce data quality standards through constraints, triggers, and other features.

  2. Databases minimize redundancy: This is also true. Databases are designed to minimize data redundancy, which means avoiding unnecessary duplication of data. This is achieved through normalization, a process that organizes data into tables to minimize redundancy and dependency.

  3. Databases can reduce application development and maintenance costs: This is true as well. Databases provide a structured and efficient way of storing, retrieving, and managing data. This can significantly reduce the time and effort required for application development and maintenance.

However, the statement that "Databases can be set up and managed without human intervention" is not typically true. While certain tasks can be automated, setting up and managing a database usually requires a database administrator or other human involvement.
