Final answer:
In an API BaaS, data is stored in managed cloud-based databases, and developers interact with this data through a series of API calls that abstract the server and database management, making application development quicker and easier.
Step-by-step explanation:
When discussing the storage of data in an API Backend as a Service (BaaS), it essentially refers to the way this platform manages data on behalf of applications. In a BaaS model, APIs are provided to enable interaction between the client application and the back-end data storage without the need to develop the back-end from scratch. The data is stored within the service's databases and is accessed through a series of API calls. These APIs define how to create, read, update, and delete (CRUD) the data, with operations typically taking place over the web using HTTP protocol.
Different BaaS platforms may use varying database types such as SQL databases, NoSQL databases, or object storage. They often support data modeling, user authentication, and other useful features intended to expedite development while maintaining scalability and security. Since these services are often managed, the developers do not have to worry about the server and database administration, scaling, or other infrastructure concerns.
Therefore, in an API BaaS, data is stored on cloud-based servers and the interactions are managed through provided APIs that handle the underlying server and database operations, simplifying the development process for app developers.
