/**
 * <p>
 * JDBC Type 4 driver DataBaseMetaData class.
 * </p>
 * Comprehensive information about the database and Type 4 driver as
 * a whole. This class lets applications users know the capabilities of database
 * in combination with the Type 4 driver. Information returned
 * by methods in this class applies to the capabilities of a Type 4 driver and
 * Database working together. A user for this class is commonly a
 * tool that needs to discover how to deal with the underlying 
 * Database. This is especially true for applications that are intended to be
 * used with more than one DBMS. For example, a tool might use the method
 * <code>getTypeInfo</code> to find out what data types can be used in a
 * CREATE TABLE statement. Or a user might call the method
 * <code>supportsCorrelatedSubqueries</code> to see if it is possible to use a
 * correlated subquery or <code>supportsBatchUpdates</code> to see if it is
 * possible to use batch updates. Some DatabaseMetaData methods return lists of
 * information in the form of ResultSet objects. Regular ResultSet methods, such
 * as getString and getInt, can be used to retrieve the data from these
 * ResultSet objects. If a given form of metadata is not available, the
 * ResultSet getter methods throw an SQLException. Some DatabaseMetaData methods
 * take arguments that are String patterns. These arguments all have names such
 * as fooPattern. Within a pattern String, "%" means match any substring of 0 or
 * more characters, and "_" means match any one character. Only metadata entries
 * matching the search pattern are returned. If a search pattern argument is set
 * to null, that argument's criterion will be dropped from the search. A method
 * that gets information about a feature that the Type 4 driver does not support
 * will throw an SQLException. In the case of methods that return a ResultSet
 * object, either a ResultSet object (which might be empty) is returned, or an
 * SQLException is thrown.
