To a model designer, a model is a collection of entities, attributes, and relationships that describe individual data points such as product id, combined into larger logical groups for example, a products entity that includes product id, product name, and other product - related data items, and then related to other groups to reflect the real - world relationships between business functions and processes for example, how products relates to inventory and sales
對于模型設計者來說，報表模型是描述各數據點（例如產品id ）的實體、屬性和關系的集合，這些實體、屬性和關系組合為較大的邏輯組（例如，包含產品id 、產品名稱和其他產品相關數據項的產品實體） ，再與其他組相關，以反映不同業務因素和過程之間的真實關系（例如，產品與庫存及銷售額之間的關系） 。 -

Abstract : data flow anomalies ( dfa ) are those anomalies related to the accessing and updating of data items in a program. the conventional dfa detection techniques alone can not be used to identify the data flow anomalies associated with the instance variables defined in a class. in this paper, a method for identifying the data flow anomalies present across the methods of a class is proposed. the method sequence specification ( mtss ) is used in conjunction with the conventional dfa detection techniques to identify the data flow anomalies in classes. this technique can ensure that there are no data flow anomalies present across methods in a class if the methods are invoked in such a way that they are compliant with the method sequence specification
文摘:數據流異常是指程序中與變量使用有關的不合常規的「可疑」情況.僅靠傳統的數據流異常檢查技術不能發現面向對象程序中與實例變量有關的數據流異常，將方法序列規范與傳統的檢查技術結合起來，提出了一種能檢查對象的實例變量的數據流異常的方法.當類中方法的調用順序符合該類的方法序列規范時，應用提出的方法能保證發現所有的介於不同方法之間的數據流異常 -
