The power of XForms really shows itself when you have data that contains homogeneous data sets at different levels, with one nested within the other.
当数据以不同级别通过嵌套方式包含同构数据集时，XForms 将尽显其功能的强大。
In contrast to lists, tuples, and dictionaries, which may contain heterogeneous elements, Numarray arrays contain only elements of a homogeneous data type.
与可以包含不同类型元素的列表、元组和词典不同的是，Numarray数组只能包含同一类型的数据。
Much of the power of the relational model comes from the fact that the relational table is the single data structure that represents homogeneous collections of data.
关系模型的大部分功能都来自于这样一个事实：关系表是代表同质数据集合的单一数据结构。
They follow the DB2 procedure model and provide a homogeneous interface that maps many special features in the data sources to DB2.
它们遵循db2过程模型并提供一个同质的接口，可以将数据源中的许多特殊特性映射到DB2。
Relational data is regular and homogeneous.
关系数据是规则且同构的。
Very often, it makes sense to display data from a homogeneous set in a table format.
以表格格式显示同构集中的数据往往很有意义。
For example, Listing 12 shows a data instance in which a top-level homogeneous set of elements consists of the three item elements.
例如，清单12显示了一个数据实例，在此数据实例中顶级的同构元素集由三个item元素组成。
The repeat element allows you to map your XForms user interface (UI) elements to a homogeneous collection in your XForms document's XML data instance.
repeat元素允许您在XForms文档的XML数据实例中将 XForms用户界面（UI）元素映射到一个同构集合。
As an international network data exchange standard, XML has a wide application foreground and powerful functions in the connection and exchange of homogeneous or heterogeneous data.
XML作为网络数据交换的标准，在同种数据或异种数据的互连和交换中，有着广泛的应用前景和强大的功能。
