摘要： A flexible and extensible architecture allows for secure searching across an enterprise. Such an architecture can provide a simple Internet-like search experience to users searching secure content inside (and outside) the enterprise. The architecture allows for the crawling and searching of a variety of sources across an enterprise, regardless of whether any of these sources conform to a conventional user role model. The architecture further allows for security attributes to be submitted at query time, for example, in order to provide real-time secure access to enterprise resources. The user query also can be transformed to provide for dynamic querying that provides for a more current result list than can be obtained for static queries.

摘要： Constraints that restrict how corresponding identifiable groups of files are stored in a database, are enforced on corresponding file data. In response to a query on any data from an identifiable group of files, the effect of the constraint on how the corresponding data is stored is determined. The original query is rewritten, based on the effect of the constraint, so that the rewritten query is directed to a particular subset of the data stored in the database. Consequently, the search space is restricted to an identifiable subset of the database and execution of the rewritten query is more efficient than execution of the original query.
摘要翻译： 在相应的文件数据上强制限制如何将对应的可识别文件组存储在数据库中。 响应于来自可识别文件组的任何数据的查询，确定约束对如何存储相应数据的影响。 基于约束的影响，原始查询被重写，使得重写的查询被定向到存储在数据库中的数据的特定子集。 因此，搜索空间限于数据库的可识别子集，并且重写的查询的执行比执行原始查询更有效。

摘要： Systems and methods that supply a replication layer/agent that is generic to supporting a plurality of storage configuration as part of a distributed store. Such distributed store employs a Common Availability Substrate (CAS) for data transport and consistency, to render the distributed store scalable and available. Such an arrangement enables continuous operation of the store, while the replication subsystem creates new replicas (e.g., for load balancing, failover, and the like).

摘要： Transformation of a set of XML documents via an XSLT stylesheet is made more efficient by rewriting the stylesheet at compile-time, based on the structural description of the set of XML documents, into an optimized stylesheet containing fewer dynamic template-matching calls than the original stylesheet. This rewritten stylesheet can be further rewritten into a set of XQuery expressions. At compile-time, the particular transformation templates that are appropriate for transforming the particular nodes contained in the set of XML documents are determined, and XSLT calls to the templates are converted to calls to corresponding XQuery user-defined functions. Determination of the appropriate transformation templates may be based on the structural description of the input set of XML documents, such as an XML Schema or Document Type Definition. The data from each template is translated into corresponding XQuery constructors, instructions from the template are translated into XQuery expressions, and the XQuery functions are inlined if possible.
摘要翻译： 通过XSLT样式表转换一组XML文档通过将编译时的样式表（基于XML文档集的结构描述）重写为优化样式表，使其具有比原始文本更少的动态模板匹配调用 样式表。 这个重写的样式表可以进一步重写成一组XQuery表达式。 在编译时，确定适合于转换XML文档集中的特定节点的特定转换模板，并将XSLT对模板的调用转换为对相应XQuery用户定义函数的调用。 确定适当的转换模板可以基于XML文档的输入集合的结构描述，例如XML模式或文档类型定义。 来自每个模板的数据被转换为相应的XQuery构造函数，模板中的指令将被转换为XQuery表达式，如果可能的话XQuery函数是内联的。

摘要： Using a WSDL document to exchange an interface definition for back-end business logic includes automatically mapping various elements of the WSDL document to corresponding XQuery elements to generate an XQuery interface definition “skeleton”. From such an XQuery interface skeleton, an XQuery statement can be generated by filling in the body of the function that implements the logic. The XQuery statement serves as an interface definition for an interface to the function. Furthermore, at runtime a Web Service request that is based on the WSDL document can be translated into an XQuery call into an XQuery function that implements the logic defined in the WSDL document. From there, results are obtained from the XQuery function, translated into the appropriate return format defined in the WSDL, and returned.

摘要： A method for optimizing queries is described. A query, which includes a first expression for determining whether each of a set of values evaluates to NULL or NOT NULL, is received. At compile-time, a first representation of the query is generated, where the first representation indicates that the query is to be performed based on the first expression. Based on the first expression, a second expression is determined. The second expression is such that the first expression would evaluate to any NOT NULL value if and only if the second expression would evaluate to any NOT NULL value. The second expression, when evaluated, is much more computationally efficient compared with the evaluation of the first expression. Based on the first representation, a second representation of the query is generated, where the second representation indicates that the query is to be performed based on the second expression. Thereafter, the query is executed based on the second representation.
