Abstract: The conception of database interaction complexity metrics is introduced based on the principle and methodology of software metrics. A vector composed of four indexes is used to represent the interaction between program and DBMS. Another vector of corresponding weight values is defined according to the need of the test of Database Application(DA). By multiplying the two vectors, the unitary complexity metrics value is calculated. Experiments show that the metric method is impersonal, accurate and flexible in measuring the interaction of DA.

Key words: Database Application(DA) software, interaction process, complexity metrics

摘要： 依据软件度量的思想和方法，提出数据库应用软件交互复杂性度量的概念。利用4个指标参量表征应用程序与数据库管理系统的交互过程，根据软件测试需要为指标指定权重向量，并通过指标向量与权重向量的乘积将4个指标归一化为一个复杂性度量值。通过实例验证表明，该方法能够客观、准确、灵活地度量数据库应用软件交互过程复杂性。
