    • A method, apparatus and computer program product, for generating a framework for supporting a homogeneous view of an information collection managed in a heterogeneous system of information storage sources. The framework includes an information collection data model mapped to an information source data model, and an information storage services data model mapped to the information source data model. The information collection data model defines information to be collected and stored as an information collection in one or more information storage sources. The information source data model references data sets containing the information defined in the information collection data model. The information storage services data model defines information storage services for accessing and performing operations on the one or more information storage sources storing the information collection. The framework allows a user to view and perform operations on the information collection without knowing how the information collection is stored.
    • 一种用于生成用于支持信息存储源的异构系统中管理的信息收集的均匀视图的框架的方法,装置和计算机程序产品。 该框架包括映射到信息源数据模型的信息收集数据模型,以及映射到信息源数据模型的信息存储服务数据模型。 信息收集数据模型将要收集和存储的信息定义为一个或多个信息存储源中的信息收集。 信息源数据模型引用了包含在信息收集数据模型中定义的信息的数据集。 信息存储服务数据模型定义用于在存储信息收集的一个或多个信息存储源上访问和执行操作的信息存储服务。 该框架允许用户在不知道如何存储信息收集的情况下查看和执行信息收集操作。

    • Systems, methods, and computer products that support techniques associated with highly reliable transaction protocol semantics in databases. Such techniques extend database transaction semantics that support a single-phase or a two-phase commit protocol to include user-defined operations while supporting the XA X/Open® Distributed Transaction Processing Protocol (“XA Transaction Protocol”). The preferred embodiment of the present invention novelly enables user-defined operations that access external resources by means of the XA Transaction Protocol to be included in database transaction processing features. Thereby user-level access to well-defined APIs is provided. Further, the preferred embodiment of the present invention novelly ensures atomicity for the results of the database transaction that includes both the user-defined operations and database operations. According to the preferred embodiment of the present invention the database acts, in part, as an XA transaction manager.
    • 支持与数据库中高度可靠的事务协议语义相关联的技术的系统,方法和计算机产品。 这种技术扩展了支持单阶段或两阶段提交协议的数据库事务语义,以包括用户定义的操作,同时支持XA X / Open(R)分布式事务处理协议(“XA事务处理协议”)。 本发明的优选实施例新颖地使得能够通过XA事务协议访问外部资源的用户定义的操作被包括在数据库事务处理特征中。 从而提供对定义良好的API的用户级访问。 此外,本发明的优选实施例新颖地确保包括用户定义的操作和数据库操作的数据库事务的结果的原子性。 根据本发明的优选实施例,数据库部分地作为XA事务管理器。
