抽象數據類型給程序員提供了極大的機動性。Frequentlythe model will encapsulate database queries, perhaps taking advantageof an abstract database class ( a data access layer ) to actually performthe queries
模型常常會封裝對數據庫的查詢，也許是為了充分利用抽象數據庫類（一個數據進程層）的優勢來進行查詢。The abstract data types of haskell in many ways provide a more straightforward route to enforcing validity than do oop attribute restrictions
與oop屬性限制相比， haskell的抽象數據類型在很多方面提供更簡單的方法來實施有效性。So far a class, an abstract data type, and a set of possible values together with operations, i. e., a data type, are pretty much the same
