For example, the Document Object Model (DOM) is a collection of objects that represent a page in a web browser, used by script programs to examine and dynamically change the page. There is a Microsoft Excel object model [1] for controlling Microsoft Excel from another program, and the ASCOM Telescope Driver is an object model for controlling an ...
The following is a comparison of cloud-computing software and providers. IaaS (Infrastructure as a service) ... ("itself" means the provider is both PaaS and IaaS ...
