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。 -
In the development process, according to the idea of modular modeling, the author rationally compartmentalized thermal system. this software has very strong graphic module edit and manage capacity, thus device interface topologic definition method is applied to define the topologic structure, and the topologic structure can be analyzed automatically and correctly. since the device module was encapsulated two parts, so, through topologic analysis, the correct source simulation program was created directly
在組態過程中，本文採用設備介面方式定義模擬系統的拓撲結構，實現了對模擬系統拓撲結構的自動識別和設備模塊的自動參數化功能，用戶只需完成模擬模型系統的構建和相應物理參數及運行工況數據的輸入，軟體便會根據拓撲分析的結果和自動參數化的結果直接生成fortran語言的模擬源程序。
