The correct answer is: A. scalability
Scalability is the ability of a system to handle an increasing amount of work, or its ability to be enlarged to accommodate that growth. In the context of databases, scalability refers to the ability of a database to handle an increasing amount of data without experiencing performance degradation.
There are two main types of scalability: vertical scalability and horizontal scalability. Vertical scalability is achieved by increasing the resources of the database server, such as the amount of memory or CPU power. Horizontal scalability is achieved by adding more database servers to the system.
Scalability is an important consideration for any database system, as it ensures that the system can continue to meet the needs of its users as the amount of data grows.
Here is a brief explanation of each option:
- A. Scalability: The ability of a system to handle an increasing amount of work, or its ability to be enlarged to accommodate that growth.
- B. Expandability: The ability of a system to be made larger or more complex.
- C. Maintainability: The ease with which a system can be kept in good working order.
- D. Platform-independence: The ability of a system to run on multiple platforms.
