A database that is accessible from a local network or the Internet is referred to as an online database. This is in contrast to a database that is kept locally on an individual computer or the storage that is associated to it (such as a CD). The websites that host online databases make their databases accessible to users in the form of software as a service products that can be accessed using a web browser. They could not cost you anything, or they might need a payment of some kind, like a regular membership fee. Some of them come along with upgraded features like collaborative editing and email notification.
The term "cloud database" refers to a database that is not hosted locally but rather on the Internet and is accessible via that medium. Therefore, rather of keeping a customer information database in a single place, a company may decide to have it hosted on the Internet instead. This will allow all of the company's departments or divisions to access it and make changes to it as needed. The vast majority of database providers include web-based interfaces for end users, which they may use in order to deploy and configure database instances.
