    • Under the present invention, a history of requests for data objects are tracked and maintained in a cache log. Based on the history, certain data objects are prefetched into a cache. When a request for a cached data object is later received, the requested data object can be retrieved from the cache and served to the requesting user. Thus, the latency involved with obtaining the data objects from the appropriate sources is eliminated. Further, under the present invention, discard and refresh rules are assigned to each data object on a class basis. Accordingly, data objects in the cache can be refreshed and/or discarded so that the caching operation can be optimized.
    • 在本发明中,对数据对象的请求历史进行追踪并保存在高速缓存日志中。 基于历史,某些数据对象被预取到高速缓存中。 当稍后接收到对高速缓存的数据对象的请求时,可以从缓存中检索所请求的数据对象并将其提供给请求用户。 因此,消除了从适当的源获得数据对象所涉及的延迟。 此外,在本发明的基础上,对每个数据对象分配丢弃和刷新规则。 因此,可以刷新和/或丢弃高速缓存中的数据对象,从而可以优化高速缓存操作。

    • A system that persistently maintains and exposes one or more previous object hierarchies to which an object belonged across one or more hierarchy destroying operations, such as operations that delete parent objects, add parent objects subsequent to addition of their descendent objects, forward objects to or from the hierarchy, and/or modify hierarchy determining rules. A user interface object allows user access to one or more persistent hierarchies for the corresponding object. A hierarchy list or the like allows a user to select a desired one of the persistent hierarchies. A persistent hierarchy can be accessed in the disclosed system through a display object associated with any object within the hierarchy, including the root, leaves, and any intervening objects. When objects are deleted, “ghost” objects are maintained and displayed to the user in the hierarchical positions of the deleted objects when a persistent hierarchy is displayed.

    • Summary information for documents are stored as entries in a table in a relational database. Each entry includes a unique identifier, value(s) for a set of attributes and rendering information for the corresponding document. A collation order is obtained that defines a sort order for the documents based on the set of attributes. An index is generated based on the collation order and includes the rendering information for each document. In response to a rendering request or other query, a query that uses index-only access for the summary table can be used to obtain the rendering information. Further, a set of marker values can be included to provide efficient navigation of the index. Still further, additional functionality can be included to display the documents in a hierarchical structure. To this extent, the invention can automatically re-categorize data when the child locations of a hierarchical location exceed a specified number and/or link other relational data to a hierarchical location.
    • 文档的摘要信息作为条目存储在关系数据库中的表中。 每个条目包括唯一标识符,一组属性的值和相应文档的呈现信息。 获得了一种根据属性集定义文档的排序顺序的归类顺序。 基于归类顺序生成索引,并且包括每个文档的呈现信息。 响应于呈现请求或其他查询,可以使用对摘要表使用仅索引访问的查询来获取呈现信息。 此外,可以包括一组标记值以提供索引的有效导航。 此外,可以包括附加功能以以层次结构显示文档。 在这种程度上,当分级位置的子位置超过指定数量和/或将其他关系数据链接到分层位置时,本发明可以自动重新分类数据。
