### Question:
TempColumnIdentifier implements ColumnIdentifier<String> { @Override public String getDbmsId() { return dbms; } TempColumnIdentifier(
        final String dbms,
        final String schema,
        final String table,
        final String column
    ); @Override String getDbmsId(); @Override String getTableId(); @Override String getColumnId(); @Override String getSchemaId(); @Override boolean equals(Object o); @Override int hashCode(); @Override String toString();  }### Answer:
@Test void getDbmsId() { assertEquals(DB, INSTANCE.getDbmsId()); }
