属性精度(attribute accuracy),指所获取的属性值(编码值)与其真实值的符合程度。实体的属性值与其真值之间的接近程度或属性值的正确性。
关于结构一致性和数据精度的问题,是通过查看列的数据属性的定义和推断来回答的。
Questions around the structural consistency and, to some extent, the precision of the data are answered by reviewing the definitions and inferences of the column's data properties.
为了在UML中创建相应的图,我们创建了两个新的构造型:用于表示XML模式属性的和用来表示双精度类型的。
To create a corresponding diagram in UML, two new stereotypes are created: to represent an XML schema attribute, and to represent a double.
通常支持的类型有整数、Boolean、ASCII字符串、双精度带符号浮点数、日期时间、集合、列表、属性。
In general supported types are Integer, Boolean, ASCII string, double-precision signed floating point number, date-time, set, list, properties.
