* In the standalone context, a main-memory database can be created (using <code>CREATE DB</code>), which can then be accessed by subsequent commands.
* If a BaseX server instance is started, and if a database is created in its context (using <code>CREATE DB</code>), other BaseX client instances can access (and update) this database (using OPEN, db:openpre, etc.) as long as no other database is opened/created by the server.* You can force an ordinary database to being copied to memory by using <code>db:openpre('some-db') update {}</code>
'''Note:''' If you address a URI with <code>fn:doc</code> or <code>fn:collection</code> for which no database exists, the resulting internal representation is identical to those of main-memory database instances (no matter which value is set for {{Option|MAINMEM}}).
