摘要
数据库规模估算是软件成本估算的基础。介绍了数据库规模的概念,运用文字叙述、表格及图形等方法分析了表类型、表结构、表元组对数据库规模的影响,设计了数据库规模估算的数学模型,并对模型中的各个参数进行了详细的解释,指出了在软件生命周期前、后阶段进行估算的方法。
The database scale estimate is the software cost estimate foundation. This paper introduces the coacept of database makes use of methods, such as writing description, form and chart type that has analyzed the table type, the table structure, the table tuples to the influence of database scale. It has designed the database acale eatimation mathematical model, has carried on the detailed explanation to each parameter in model, and points out the estimation method in the software life cycle back and forth stage.
