In 2003, CEO Fred Luddy started a company called GlideSoft, which specialized in IT Service Management applications. Three years later, the company changed its name to ServiceNow, but the Glide name stuck for the API!
The Glide API is available on both the server and the client (though only a subset of the API is available on the client), and it consists largely of several classes about which we'll learn in this chapter; several of which are:
Server-side Glide classes:
GlideRecordGlideAggregateGlideElementGlideDateandGlideDateTimeGlideSessionGlideSystem
Client-side Glide classes:
GlideRecordGlideAjaxGlideFormGlideList2GlideMenuGlideUser
Each class in the Glide API may consist of methods (executable functions within the class), and properties (variables stored within the class, which may be set on initialization of a new instance of the class).
