The ServiceNow Glide classes
expose JavaScript APIs that enable you to conveniently work with tables using
scripts.
Using the Glide APIs, you can perform database operations without writing SQL queries,
display UI pages, and define UI actions. The following tables provide brief descriptions of
the Glide classes and links to detailed information.

See [GlideAggregate](https://www.servicenow.com/docs/access?context=c_GlideAggregateScopedAPI&version=yokohama&pubname=yokohama-api-reference&ft:locale=en-US). |
| GlideDateTime | Use this class to perform date-time operations, such as date-time calculations, formatting a date-time, or converting between date-time formats. See [GlideDateTime](https://www.servicenow.com/docs/access?context=c_GlideDateTimeScoped&version=yokohama&pubname=yokohama-api-reference&ft:locale=en-US). |
