    • Techniques to prioritize and optimize the execution of upgrade operations are described. A technique may include determining the size of data blocks that are to be copied from one storage medium to another, and the dependencies of upgrade tasks on the data blocks and on other tasks. A task may be prioritized according to a weight that includes the cumulative sizes of the data blocks that it and its dependent tasks depend on. A data block copying may be prioritized according to the cumulative weights of the tasks that depend on that data block. Some embodiments may perform several data copying and/or tasks in parallel, rather than sequentially. Other embodiments are described and claimed.
    • 描述了优先级和优化升级操作执行的技术。 技术可以包括确定要从一个存储介质复制到另一个存储介质的数据块的大小,以及升级任务对数据块和其他任务的依赖性。 可以根据包括其及其从属任务所依赖的数据块的累积大小的权重优先考虑任务。 可以根据依赖于该数据块的任务的累积权重来优先考虑数据块复制。 一些实施例可并行执行若干数据复制和/或任务,而不是依次执行。 描述和要求保护其他实施例。

    • Enterprise systems, methods and computer program products are disclosed for providing caching of data retrieved from joined tables and an inheritance table hierarchy of a database in an enterprise. The computer implemented method comprises creating a queue of cursors of a statement associated with a database; evaluating a cursor of the queue and marking as one of a unique record and an object of an inheritance table; and, if a cursor of the queue is marked as one of a unique record and a unique object, then, storing data associated with one of the unique record and object in a data cache for subsequent retrieval, thus avoiding costly network calls. If the process leaves a cursor unevaluated, the method retrieves data from an enterprise database associated with the statement. The process is implemented on an application object server including a data access layer and a kernel instance.
    • 公开了企业系统,方法和计算机程序产品,用于提供从连接表检索的数据的缓存和企业中数据库的继承表层次结构。 计算机实现的方法包括创建与数据库相关联的语句的游标队列; 评估队列的游标并将其标记为唯一记录和继承表的对象之一; 并且如果将队列的光标标记为唯一记录和唯一对象之一,则将与唯一记录和对象中的一个相关联的数据存储在数据高速缓存中用于后续检索,从而避免昂贵的网络呼叫。 如果进程离开游标,该方法将从与该语句关联的企业数据库中检索数据。 该过程在包括数据访问层和内核实例的应用对象服务器上实现。

    • Enterprise systems, methods and computer program products are disclosed for providing bulk create (insert), update and delete operations for table inheritance in an enterprise resource system using an object-oriented language supporting polymorphism. The computer implemented method comprises receiving a request for one of a create, update and delete operation with respect to data of first and second tables of an inheritance table hierarchy; creating a temporary table comprising a surrogate key and a record identifier; establishing a filter condition with fields from different tables in table inheritance; and one of creating, updating and deleting data from the different tables in table inheritance according to the filter condition. The process is implemented on an application object server including a compiler for the object-oriented language, a kernel instance and a data access layer.
    • 公开了企业系统,方法和计算机程序产品,用于在使用面向对象语言支持多态的企业资源系统中提供用于表继承的批量创建(插入),更新和删除操作。 计算机实现的方法包括接收关于继承表层次结构的第一和第二表的数据的创建,更新和删除操作之一的请求; 创建包括代理密钥和记录标识符的临时表; 在表继承中使用来自不同表的字段建立过滤条件; 以及根据过滤条件在表继承中创建,更新和删除不同表中的数据之一。 该过程在包括用于面向对象语言的编译器,内核实例和数据访问层的应用对象服务器上实现。
