摘要： A system and method are provided for XML query cursor implementation through the steps of query translation and processing, query result navigation, and positioned update. An XML query cursor implemented in Interface Definition Language (IDL) as well as an extension to XQuery, an XML query language, is described. These steps are addressed by one of three approaches: multi-cursor, outer union, or hybrid. In each approach, XML data is assumed to be stored in a relational database with a mapping that maps each element to a row in a relational database table. In each approach, a system and method provide for cursor movements and positioned updates in increments of a node, sub-tree, or entire document. Given a user's navigation patterns, a system and method is provided to select either a multi-cursor, outer union, or hybrid approach as an optimal implementation for an XML query cursor.

摘要： A content management system is provided including a library server in which user and system metadata is stored in a plurality of tables forming a tree-based storage hierarchy. The metadata is stored in a first data format compatible with a complex query language such as Structured Query Language (SQL). A query processor in the library server maps the first data format to a second data format which is compatible with a simpler query language such as XML query language. A client's user experience is substantially simplified when queries are presented to the system.
摘要翻译：提供了一种内容管理系统，其包括库服务器，其中用户和系统元数据存储在形成基于树的存储层级的多个表中。元数据以与诸如结构化查询语言（SQL）的复杂查询语言兼容的第一数据格式存储。库服务器中的查询处理器将第一数据格式映射到与诸如XML查询语言之类的更简单的查询语言兼容的第二数据格式。当向系统呈现查询时，客户端的用户体验将大大简化。
