Which of the following is true regarding database scalability?

The statement regarding database scalability is accurate in that it indicates the database's ability to increase its size without experiencing performance loss. This characteristic is critical for systems expected to handle growing amounts of data or user demand over time. Scalability is important because businesses may start with a small database, but as they expand, their data needs will increase. A well-designed database can maintain its performance even as it scales in size, ensuring that queries remain efficient and that the system can support increased loads without degrading the user experience.

In contrast to other options, this definition of scalability encapsulates both the technical capabilities of the database and the practical implications for operational performance. While ensuring scalability, it is also essential to manage data integrity; however, it does not diminish the importance of scalability itself. Performance optimization can be a factor within scalability but is not the sole focus, as scalability encompasses the broader ability to accommodate growth. Frequent schema evolution may be necessary in some cases, but it is not a definitive requirement for scalability, as a scalable database can be achieved with a stable schema, adapting only when needed to support growth.
