database for my small sites



i plan to have various small sites that will use wordpress but on my hosting account i have 25 databases available. i do not want to use a separate database for each
can i use one database and separate it into smaller sites? i know that during installation of wordpress it gives us an option like that

but how does it work, do you recommend it? do i make sense? what may be the disadvantages?
Yes, you can use WordPress Multisite to manage multiple sites with a single database. It simplifies management, saves resources, and allows centralized user management. However, it adds complexity, may have compatibility issues with some plugins/themes, and lacks complete data separation. Consider your specific needs before deciding.
