    • Two-way digital media devices typically store digital identifying data that identify the user to providers of content and interactive data. In the case of a Web browser of a personal computer, the digital identity is stored in the form of a plurality of cookies that are used by respective web sites to personalize the web site experience for each particular user. When a user is at a different computer, the digital identifying data is not available. In addition, other types of interactive devices, such as CATV settop boxes, cell phones, PDAs and the like, may not have enough non-volatile memory (persistent storage) to store the digital identifying data. In order to provide users with a portable digital identity, a digital identity server is provided as a server node on the Internet, which retrieves digital identifying data and downloads such digital identifying data to any device upon request. In such manner, the user's digital identity is portable and available at any computer or other digital device that is being used. The system digital identity server permits devices without sufficient non-volatile memory storage to download a digital identity for temporary storage in volatile memory, thereby providing a digital identity in devices without non-volatile memory.
    • 双向数字媒体设备通常将识别用户的数字识别数据存储到内容提供者和交互式数据。 在个人计算机的Web浏览器的情况下,数字身份以多个cookie的形式存储,由各个网站使用,以个性化每个特定用户的网站体验。 当用户处于不同的计算机时,数字识别数据不可用。 此外,诸如CATV机顶盒,手机,PDA等其他类型的交互式设备可能没有足够的非易失性存储器(持久存储器)来存储数字识别数据。 为了向用户提供便携式数字身份,数字身份服务器被提供为因特网上的服务器节点,其检索数字识别数据,并且根据请求将这样的数字识别数据下载到任何设备。 以这种方式,用户的数字身份是便携式的,并且在正在使用的任何计算机或其他数字设备上可用。 系统数字身份服务器允许没有足够的非易失性存储器存储的设备下载用于在易失性存储器中临时存储的数字身份,从而在不具有非易失性存储器的设备中提供数字身份。

    • The processing of object-oriented queries so as to retrieve data from a relational database management system (RDBMS) is described. An object-oriented query and at least one prefetch path are received from an object-oriented source (such as an application or user). The prefetch path identifies one or more objects which are desired to be constructed. The object-oriented query is translated to a translated object query, where the translated object query is a relational database query capable of retrieving from the RDBMS data to initialize base attributes of top-level objects identified by the object-oriented query. A set of relational queries is generated from the translated object query and the prefetch path. These relational queries, which are capable of retrieving from the RDBMS data needed to construct the objects identified by the prefetch path, are processed by the RDBMS.
    • 描述了面向对象查询的处理,以便从关系数据库管理系统(RDBMS)中检索数据。 从面向对象的源(例如应用或用户)接收面向对象的查询和至少一个预取路径。 预取路径标识希望构造的一个或多个对象。 将面向对象的查询转换为翻译对象查询,其中翻译的对象查询是一种关系数据库查询,能够从RDBMS数据中检索以初始化面向对象查询所标识的顶级对象的基本属性。 从转换的对象查询和预取路径生成一组关系查询。 这些关系查询能够从构建由预取路径标识的对象所需的RDBMS数据中检索,由RDBMS处理。
