    摘要： Disclosed is a data processing system implemented method, a data processing system and an article of manufacture for improving execution efficiency of a database workload to be executed against a database. The database includes database tables, and the database workload identifies at least one of the database tables. The data processing system includes an identification module for identifying candidate database tables being identifiable in the database workload, the identified candidate database tables being eligible for organization under a clustering schema, a selection module for selecting the identified candidate tables according to whether execution of the database workload is improved if the selected identified candidate table is organized according to the clustering scheme, and an organization module for organizing the clustering schema of the selected organized identified candidate tables prior to the database workload being execution against the database.

    摘要： A system and method of converting a recursive XML document into a relational schema comprises providing a recursive XML document; parsing an external mapping script specifying a mapping from the recursive XML document to a relational table format; building a recursive shredding tree based on the external mapping script and the relational table format; and shredding the mapped recursive XML document into a relational table. The system and method further comprise detecting whether any of a XML schema and a DTD document is recursive, wherein the detecting comprises building a directed graph comprising element names; corresponding elements names as nodes in the directed graph; forming arcs from every element parent node to every element child node of the element parent node; and checking for cycles in the directed graph. The system and method further comprise identifying all recursive cursor nodes and a recursive degree corresponding to the recursive shredding tree.

    摘要： A repository index records the position of document entries relative to landmark entries within the document. Landmark entries are selecting using a landmarking policy and their position relative to the document are stored in a landmark directory. During index updates, an edit transcript is generated describing the difference between old and new document versions, and both the document repository index and the landmark directory are updated as needed. Thus, the number of update operations preformed as compared with conventional indexing techniques may be substantially reduced when small, localized changes are made to the document. This is due to fact that the positions of document entries are recorded relative to the landmark entries rather than the document itself. By doing so, the document index becomes more shift-invariant, requiring fewer update operations when entries are added or inserted in localized areas of the document.

    摘要翻译： 存储库索引记录文档条目相对于文档中的地标条目的位置。 地标条目正在使用标记政策进行选择，并且相对于文档的位置将存储在地标目录中。 在索引更新期间，生成描述旧文档版本和新文档版本之间的差异的编辑脚本，并根据需要更新文档存储库索引和地标目录。 因此，与传统的索引技术相比，执行的更新操作的数量可以在对文档进行小的局部改变时被显着地减少。 这是因为文件条目的位置相对于里程碑条目而不是文档本身被记录。 通过这样做，文档索引变得越来越不变，当在文档的本地化区域中添加或插入条目时，需要更少的更新操作。
