The INSERT statement does not need to specify the value for the SERIALNUMBER column .
INSERT语句不需要指定SERIALNUMBER列的值。

Doing so allows me to define the common properties such as SerialNumber only once and will also simplify associations by allowing the Property class to be the associated with the Theft class .
这样做的话,我只需定义一次SerialNumber等公共属性,还能通过允许Property类关联到Theft类来简化关联。
