Which of the following options is NOT a consideration when selecting a database solution?

Selecting a database solution involves multiple factors that can significantly impact the performance, cost, and reliability of an application. The consideration of database performance is crucial as it defines how quickly and efficiently a database can execute queries and process transactions. This directly affects user experience and application speed.

Storage cost is also an important factor since it plays a key role in budget management for database operations. Understanding how much data will be stored and how that cost will grow over time is essential for effective financial planning.

Data consistency requirements are fundamental when selecting a database as they determine how the database should handle transactions and concurrent data access, especially in distributed systems. Ensuring the right level of consistency (e.g., eventual consistency vs. strong consistency) is vital for maintaining data integrity based on the application's needs.

Considering the minimum concurrent users to support is not typically a primary factor when selecting a database solution. While scalability is important, it is more a function of the underlying architecture and database choice rather than a direct consideration like performance, cost, and consistency. Many databases can handle user concurrency in ways that can be optimized later, making it less essential to weigh against the other primary factors during initial selection.
