Answer:
Scalable database
Step-by-step explanation:
Good examples of a scalable database include; NoSQL database, MySQL, Microsoft SQL.
Remember, these databases are called scalable databases because they support memory expansion without a measurable performance decrease.
For example, if the management of a hotel notices that its 1 terabyte computer used to store its security videos is no longer adequate to meet the hotel's expansion, then decide to buy a newer server that can be integrated into the current system. We can say they just applied the concept of scalable databases.
