Abstract class
Instances of this class identify a database to a DBMS. It is the root class of all database classes, and a subclass of <object>.
If you apply make to the class <database> within the scope of the with-dbms macro, an instance of a DBMS-specific database class is created.
The SQL-ODBC library defines a class <odbc-database> for identifying a database to an ODBC DBMS.
