To persistence the objects there are two common approach. one approach is that structured query language ( sql ) codeis embedded in the source code of your classes. the other approach is that sql statements for your business classes are encapsulated in one or more " data classes. " the disadvantage is that it directly couples your business classes with the schema of your relational database, implying that a simple change such as renaming a column or porting to another database results in a rework of your source code
實現在關系數據庫存取對象，常用的做法有：一種方法是在對象中直接編寫sql代碼來存取對象，另一種方法是將sql代碼在專門的數據類（或存儲過程）中編寫，但著兩種方式都使得對象模型與關系數據庫模式的耦合度大，不容易維護，因為關系數據庫模式的微小改動，都將導致應用程序的重新編譯。
