Complex query strings, normal form optimization, and the procedural nature of SQL are abstracted via JDO, allowing a development team to focus on the core of their application's persistence needs.
复杂查询字符串、范式优化和SQL的过程性质都通过JDO得以抽象，从而使开发小组可以将精力集中在他们的应用的持久性需求这个核心上。
This optimization feature enables applications to efficiently query XML data through a traditional relational interface with SQL queries.
