DataSet class in Java?
提问by User1
Does anyone know if there is a DataSet class in Java like there is in .Net? I am familiar with EJB3 and the "java way" of doing data. However, I really still miss the seamless integration between database queries, xml and objects provided by the DataSet class. Has anyone found a Java implementation of DataSet (including DataTable, DataRow, etc)?
有谁知道 Java 中是否有像 .Net 中那样的 DataSet 类？我熟悉 EJB3 和处理数据的“java 方式”。但是，我还是很怀念DataSet 类提供的数据库查询、xml 和对象之间的无缝集成。有没有人找到 DataSet 的 Java 实现（包括 DataTable、DataRow 等）？
Edit: Also if anyone has tutorials for the java flavor of DataSet, please share a link.

Have you looked at javax.sql.rowset.WebRowSet?
你看过javax.sql.rowset.WebRowSet吗？
From the Javadocs:
来自 Javadocs：
The WebRowSetImpl provides the standard reference implementation, which may be extended if required.
The standard WebRowSet XML Schema definition is available at the following URI:
http://java.sun.com/xml/ns/jdbc/webrowset.xsdIt describes the standard XML document format required when describing a RowSet object in XML and must be used be all standard implementations of the WebRowSet interface to ensure interoperability. In addition, the WebRowSet schema uses specific SQL/XML Schema annotations, thus ensuring greater cross platform inter-operability. This is an effort currently under way at the ISO organization. The SQL/XML definition is available at the following URI:
http://standards.iso.org/iso/9075/2002/12/sqlxml
WebRowSetImpl 提供了标准参考实现，如果需要，可以对其进行扩展。
标准 WebRowSet XML 架构定义在以下 URI 中可用：
http://java.sun.com/xml/ns/jdbc/webrowset.xsd它描述了在 XML 中描述 RowSet 对象时所需的标准 XML 文档格式，并且必须用于 WebRowSet 接口的所有标准实现以确保互操作性。此外，WebRowSet 模式使用特定的 SQL/XML 模式注释，从而确保更大的跨平台互操作性。这是 ISO 组织目前正在进行的一项工作。SQL/XML 定义在以下 URI 中可用：

I know what you mean by the "dataset way" maybe you can find something similar, however are you sure you want to go that way? Java has many options but if you want something more cooked, why don't explore hibernate, it's the very popular in the industry and will give you more power that the one you are asking for.
我知道您所说的“数据集方式”是什么意思，也许您可以找到类似的东西，但是您确定要那样做吗？Java 有很多选择，但是如果您想要更成熟的东西，为什么不探索 hibernate，它在行业中非常流行，并且会为您提供比您所要求的更强大的功能。

You might be looking for LINQ implementation in Java. IMHO better than the DataSet/DataTable route.
您可能正在寻找 Java 中的 LINQ 实现。恕我直言，比 DataSet/DataTable 路线更好。

you may want to look into this open-source library:
你可能想看看这个开源库：
https://www.developerfusion.com/project/20506/casperdatasets/
https://www.developerfusion.com/project/20506/casperdatasets/
Its easy to use (a lot like using the sql resultset), and its all in-memory. it also supports complex queries and indexes on your data.
它易于使用（很像使用 sql 结果集），并且全部在内存中。它还支持对数据进行复杂的查询和索引。

I'm an author of ExDataSet. If you need a way to send DataSet from java/android application to .NET the web service, you should take a look on this library. It is 100% fully compatible in xml representation with .NET DataSet objects and supports sending tables, rows, relations, foreign and unique keys, nested tables etc.
我是ExDataSet的作者。如果您需要一种将数据集从 java/android 应用程序发送到 .NET 网络服务的方法，您应该看看这个库。它在 xml 表示中与 .NET DataSet 对象 100% 完全兼容，并支持发送表、行、关系、外键和唯一键、嵌套表等。

Made one myself. Only have DataTable and DataRow, and might be incomplete. Check:
自己做了一个。只有DataTable和DataRow，可能不完整。查看：
