摘要： Described is programmatic access to persistent XML and relational data from applications based upon explicit mappings between object classes, XML schema types, and relations. The mappings are used in data access, that is, they drive query and update processing. A query may be processed into a query for accessing the XML data and another query for second type for accessing the relational data. Mappings support strongly-typed classes and loosely-typed classes, and may be conditional upon other data, may decouple query and update translation performed at runtime from schema translation used at compile time, and/or may be compiled into transformations that produce objects from XML data and transformations that produce XML data from objects. Mappings may be generated automatically or provided by the developer.

摘要： A data structure may exist in various representations, such as an object in an object-oriented system or a set of elements included in an extensible markup language (XML) document structured according to an XML type defined in an XML schema. While many aspects of these representations may correspond, some aspects of an XML document may not be specified by the XML schema (such as developer comments, whitespace, and preprocessor directives), and may be lost while translating an XML representation of the data structure to an object. These non-schematized aspects may be included in the object as a delta, specifying the location of an aspect with relation to an element defined by the XML schema. Preserving non-schematized aspects may promote the full representation of the data structure as an object, and may facilitate a full-fidelity regeneration of the XML document from which the object was generated.
摘要翻译：数据结构可以存在于各种表示中，例如面向对象系统中的对象或根据在XML模式中定义的XML类型而构造的可扩展标记语言（XML）文档中的一组元素。虽然这些表示的许多方面可能对应，XML文档的某些方面可能不被XML模式（例如开发人员注释，空白和预处理指令）指定，并且可能在将数据结构的XML表示转换为一个东西。这些未示意的方面可以作为增量包含在对象中，指定与由XML模式定义的元素相关的方面的位置。保留非示意性方面可以促进数据结构作为对象的完全表示，并且可以促进对象被生成的XML文档的完全保真再生。

摘要： Architecture that maps document data (e.g., XML-extended markup language) into columns of one table, thereby avoiding schema normalization problems through special data storage. Moreover, an algorithm is described that can translate a query (e.g., in XPath (XML path language), a query language for navigating through document elements and attributes of an XML document) into a relational algebra query of the document column representation. Based on the characteristics of the new mapping, query rewriting rules are provided that optimize the relational algebra query by minimizing the number of joins. The mapping of XML documents to the table is based on a summary structure and a hierarchical labeling scheme (e.g., ordpath) to enable a high-fidelity representation. Annotations are employed on the summary structure nodes to assist in mapping XML elements and attributes to the table.
摘要翻译：将文档数据（例如，XML扩展标记语言）映射到一个表的列中的架构，从而通过特殊数据存储来避免模式规范化问题。此外，描述了可以将查询（例如，XPath（XML路径语言），用于浏览文档元素和XML文档的属性的查询语言）转换为文档列表示的关系代数查询的算法。基于新映射的特征，提供查询重写规则，通过最小化联接数来优化关系代数查询。将XML文档映射到表是基于总结结构和分层标签方案（例如ordpath）来实现高保真度表示。在摘要结构节点上使用注释来帮助将XML元素和属性映射到表中。

摘要： Aspects of the subject matter described herein relate to automating evolution of schemas and mappings. In aspects, mappings between a conceptual model and a store model are updated automatically in response to a change that occurs to the conceptual model. For example, when a change occurs to the conceptual model, a local scope of the change is determined. The local scope indicates mappings that are most similar to the type(s) affected by the change. Based on the local scope, a pattern of mappings between the conceptual model and the store model is determined. Using this pattern and the nature of the change, the mappings are updated according to the pattern. In addition, the store model and data thereon may be updated in a manner to preserve existing data that is not to be deleted in response to the change.

摘要： Aspects of the subject matter described herein relate to incrementally modifying schemas and mappings. In aspects, an indication of a change to a client schema is received and a compilation directive is received. The compilation directive may indicate how one or more entities or associations in the client schema are to be mapped to the store schema. In response to receiving the indication of the change and the compilation directive, mapping data and storage schema may be incrementally modified with incremental revalidation and incremental updating of query and update views.
