Cloud Database Services are online platforms that allow users to store, manage, and access data over the internet. Instead of relying on local servers or physical hardware, these services provide scalable and flexible solutions that can grow with a business's needs. They often come with built-in security features and automatic backups, ensuring data is safe and easily retrievable. These services can be categorized into two main types: SQL databases, which use structured query language for data management, and NoSQL databases, which are designed for unstructured data. Popular providers include Amazon Web Services, Google Cloud, and Microsoft Azure, each offering various tools and features to support different applications.
