What is the term for a cloud-based service model that provides data on demand?

The correct answer is the term "Data as a Service" (DaaS). This model supports the provision of data on demand, enabling users to access data regardless of their location or device, which can significantly enhance decision-making processes. DaaS simplifies data management and reduces the complexities associated with traditional data handling and storage approaches, facilitating seamless access to data.

In contrast, the other models focus on different aspects of cloud services. Software as a Service (SaaS) refers to software applications hosted in the cloud, where users can access and use software without the need for local installation. Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, including servers and storage. Platform as a Service (PaaS) offers a platform allowing developers to build, deploy, and manage applications without dealing with the underlying infrastructure. Each of these models serves different purposes within cloud computing, emphasizing that DaaS specifically addresses the delivery and accessibility of data itself on an on-demand basis.
