An element generally refers to a data column in the record, such as the number field on a task record, or the sys_updated_on field of a record. You can access a GlideElement from a server-side GlideRecord object (for example, by using gr.number), or by using the getElement method of a GlideRecord object.

Let's say for example, that we have a table with a column called short_description. When we query this table, we get a GlideRecord object populated with various properties. Each field in the table becomes a property in the GlideRecord object, but those...
