domain-focused rules that are somewhat advanced are most often much easier to express in the Domain Model than in a Relational database,

这句话中有两个“are”怎么理解啊？

第一个are是rules引导的定语从句that are somewhat advanceed的be动词;
第二个are是domain-focused rules的be动词,把that are somewhat advanced 这个从句拿掉你就可以看出来了~~
我换个写法你就明白了：
domain-focused rules,which are somewhat advanced,are most often easier....
