Final answer:
The criterion for classifying a database system based on the number of users is split into single-user and multi-user classifications. This classification helps determine the infrastructure and management needs for the database based on user demand.
Step-by-step explanation:
One criterion for classifying a database system is according to the number of users who can use the system. This classification can be broadly put into two categories: single-user and multi-user database systems. A single-user database is typically used by one person at a time, usually on a personal computer or local workstation. A multi-user database, on the other hand, supports multiple users concurrently accessing the database, often across a network. Just as the SCV design team considered various criteria and constraints for their design, in database systems, we must also determine criteria for classification based on specific goals and needs. For instance, classifying a database based on the number of users is very useful for understanding the capabilities and performance requirements of a database system. It helps in deciding the necessary hardware, software, and management capabilities needed to run the database efficiently and effectively for its intended use.
