Description

Technical Field

[0001] The present invention relates to the field of rural broadcasting information technology, and in particular to an Internet-based SaaS rural broadcasting system and method. Background Art

[0002] SaaS is a model of providing software through the Internet. Manufacturers deploy application software on their own servers. Customers can order the required application software services from manufacturers through the Internet according to their actual needs, pay the manufacturer according to the amount of services ordered and the length of time, and obtain the services provided by the manufacturer through the Internet. Users no longer need to purchase software, but instead rent Web-based software from providers to manage business operations, and there is no need to maintain the software. Service providers will fully manage and maintain the software. While providing Internet applications to customers, software manufacturers also provide offline operation of the software and local data storage, allowing users to use the software and services they ordered anytime and anywhere. For many small businesses, SaaS is the best way to adopt advanced technology. It eliminates the need for enterprises to purchase, build and maintain infrastructure and applications.
