A java framework could possibly simulate some of what active record offers , but creating something like active record would be challenging , possibly breaking three existing java conventions Java框架应当也可以模拟活动记录提供的一些功能，但是创建像活动记录一样的东西可能是个挑战，可能会破坏三个现有的java约定：
Active record doesn t require a mapping file , as hibernate does ; in fact , a developer working with active record doesn t need to code getters or setters , or even the properties of the class 与hibernate一样， active record不需要映射文件；实际上，使用active record的开发人员不需要对getter或setter 、甚至类的属性进行编码。
Martin fowler describes an active record as " an object that wraps a row in a database table or view , encapsulates the database access , and adds domain logic on that data .
