为了最大化互操作性，对于每个仅描述其预期或产生的数据类型的事件，您应该为其声明一个别名，换句话说，这就是最低兼容性要求。
To maximize interoperability, you should declare an alias for each event that describes just the data type that it expects or produces; in other words, the minimum requirement for compatibility.
另一个重要的任务是确定源数据库和新数据库之间的数据类型的兼容性。
Another important task is to determine the compatibility between the data types in the source database and in the new database.
MySQL to DB 2 Conversion Guide的6.1节(见参考资料)介绍了每一种数据类型，并用一个表格介绍了数据兼容性。
