Compared to [[QUERY|online / server side queries]], offline queries provide a similar capability to query for objects that match the criteria defined by the query objects. The major differences are:
* The querying happens entirely offline without the need of networks;
* Only local objects already available on the client can be found as query results (for obvious reasons).
{{Hint|The [[SYSCLS_OFFLINE_QUERY|offline query classification]] is primarily needed on the Scope of the offline query, rather than on the MetaClass itself, because the client evaluates the classification.}}
