- Only one space after a period (using two spaces is last century).
- Rename dateClass to dateTimeClass
- Rename *Clazz to *Class
- Use more appropriate method names ("find" for me implies the method might return null)
- Add missing Javadoc comments
- Java field names can end with *Value, but *_value isn't Java style
- Use appropriate variable names ("cn" isn't, "lower" is)
- Use more appropriate method names (getClassForSqlType versus getClassType, createClassName versus convertTableToClassName, createFieldName versus convertColumnToFieldName)
