Database as a Service (DBaaS) is a cloud computing service that allows users to access and manage databases without the need for physical hardware or complex software installations. It provides a scalable and flexible solution, enabling businesses to store, retrieve, and analyze data efficiently while reducing the burden of database maintenance. With DBaaS, users can focus on their applications and data rather than managing the underlying infrastructure. This service typically includes features like automated backups, security, and performance monitoring, making it easier for organizations to leverage data for decision-making and growth without extensive technical expertise.
