The page refers to it as a structured data type similar to variables in Python or Perl.
这个页面将其称作一个类似于Python或Perl中的变量的结构化数据类型。
A structured data type is a form of user-defined data type that contains a sequence of attributes, each of which has a data type.
结构化数据类型是一种用户定义的数据类型，它包含了一系列的属性，每一个属性都有一个数据类型。
Thus we see that a structured data type can have operations defined on its composite values, as well as on the component elements of those values.
由此我们知道数据结构可以有定义在其构成值之上的操作。也有定义在这些值的组成元素上的操作。
We will call any data type whose values are composed of component elements that are related by some structure a structured data type, or data structure.
我们称其值由组成元素组成，且这些组成元素通过某种结构而彼此相关，类型结构为结构化数据类型或数据结构。
A structured data type can be used as the type for a column in a regular table (Listings 1 and 2), the type for an entire table (or view), or as an attribute of another structured type (Listing 3).
结构化数据类型可以用作普通表中某一列的类型(清单1和清单2)，也可以用作整个表(或视图)的类型，或者用作另一个结构化类型的属性(清单3)。
They can also store structured type columns or index data.
它们还可以存储结构化类型的列或索引数据。
If the column is a structured type column, you specify the name of the structured type as its data type (Listing 1).
如果列是结构化类型列，则需要将结构化类型的名称指定为其数据类型(清单1)。
But maps lack some of the features expected of structured data: they have no real "type" (without added metadata) and, unlike classes, they can't be extended with new behavior.
但是映射缺乏一些结构化数据的预期功能：它们没有真实的“类型”(在不添加元数据的情况下)，不像类那样，它们不能通过新的行为扩展。
The HTML looks structured as described here, but not the type of structure that applies the latent meaning to the data.
根据这里的描述，HTML看起来像结构化数据，但不是将隐藏语义应用到数据的结构类型。
The FROM SQL clause defines the specific function that will be used to transform a value to a built-in data type value representing the structured type.
FROMsql子句定义了特定的函数，可以使用该函数将将一个值转换成表示结构化类型的内置数据类型。
To retrieve structured type data from a table, there must be some way to convert that type into a single scalar value whose type, in turn, must be based on one of the built-in DB2 data types.
为了从表中检索结构化类型数据，必须有一些将类型转换成一个标量值，换句话说，这些值的类型必须基于某种内置的DB2 数据类型。
You can create a table with structured type columns in the same way that you would create a table using only DB2 built-in data types.
您可以用同样方式使用结构化类型列创建表，也可以只使用DB 2内置数据类型创建一个表。
Each of these is a complex data type containing structured information describing specific platform qualities.
这三个类中的每个类都是一个复杂的数据类型，包含用于描述特定平台性质的结构化信息。
The REF USING INTEGER clause specifies that the INTEGER data type will be used to represent the REFERENCE type of this structured type and all of its subtypes.
REF USINGINTEGER子句指定了 INTEGER数据类型，将使用这个数据类型表示该结构化类型及其所有子类型的 REFERENCE 类型。
The type of data that you analyze—structured versus unstructured
分析的数据的类型 —结构化的还是非结构化的
