by Most Patent Citation in the China in 2019

In computing, data as a service (or DaaS) is a cousin of software as a service (SaaS). Like all members of the "as a service" (aaS) family, DaaS builds on the concept that the product (data in this case) can be provided on demand to the user regardless of geographic or organizational separation of provider and consumer. Additionally, the emergence of service-oriented architecture (SOA) and the widespread use of application programming interface (API) has also rendered the actual platform on which the data resides irrelevant. This development has enabled the emergence of the relatively new concept of DaaS.
