    摘要： The present invention extends to methods, systems, and computer program products for scoping the context used to access a database partition. Embodiments of the invention enable data isolation using partitions in multi-tenant databases, while relieving client applications from dealing with the partitions. For example, a computer system that includes a distributed database system comprising a plurality of database partitions in a federation receives a context to use when performing database access operations within the distributed database system. The context identifies specified relevant portion of the federation. The computer system also receives a database access operation that is associated with the context. The computer system modifies the semantics of the database access operation in accordance with the associated context, to direct application of the database access operation to the specified relevant portion of the federation.

    摘要翻译： 本发明扩展到用于范围界定用于访问数据库分区的上下文的方法，系统和计算机程序产品。 本发明的实施例使得能够在多租户数据库中使用分区进行数据隔离，同时减轻客户端应用程序处理分区。 例如，包括在联合体中包括多个数据库分区的分布式数据库系统的计算机系统接收在分布式数据库系统中执行数据库访问操作时要使用的上下文。 上下文标识了联盟的指定相关部分。 计算机系统还接收与上下文相关联的数据库访问操作。 计算机系统根据相关联的上下文来修改数据库访问操作的语义，以将数据库访问操作的应用直接引导到联盟的指定相关部分。

    摘要： A system for protecting against erosion the surface of a body which is subjected to an airflow and consists essentially of a fibrous material or a fiber-reinforced plastic material, such as a rotor blade, has a metallic coating which, in the respective area to be protected, covers the surface in several layers. The primary layer of the coating consists of aluminum or a similar material with a modulus of elasticity that is approximately identical to that of the material on the surface of the body. The primary layer, in the form of a sheet glued to the surface, is coated with a two-phase material, in which particles of metallic oxide and/or metallic carbide and/or metallic nitride compounds are embedded in a finely distributed manner in a ductile, solid-solution-hardened matrix of a metallic but non-ferrous material.
