Abstract: A method and system for converting source tables of a database of the application to target tables of a new version of the database while reducing the amount of time that the database needs to be open in single-user access mode is provided. A conversion system divides the conversion into a multi-user phase and a single-user phase. During the multi-user phase, the conversion system can perform most of the conversions while the database is opened in multi-user access mode. The conversion system stores the converted data in auxiliary tables, rather than updating the source tables. During the single-user phase, the conversion system performs the remaining conversions and copies data from the source tables and the converted data from the auxiliary tables to the target tables.

Abstract translation: 提供了一种方法和系统，用于将应用程序的数据库的源表转换为数据库的新版本的目标表，同时减少数据库需要在单用户访问模式下打开的时间量。 转换系统将转换分为多用户阶段和单用户阶段。 在多用户阶段，转换系统可以在数据库以多用户访问模式打开时执行大部分转换。 转换系统将转换的数据存储在辅助表中，而不是更新源表。 在单用户阶段期间，转换系统执行剩余的转换，并将数据从源表和从辅助表转换的数据复制到目标表。

Abstract: A method and system of Digital Rights Management (DRM) in a consumer environment where the DRM agent and the rendering application are implemented on separate devices is provided. A first control message is transmitted from the rendering application to notify the DRM agent about the details of a content consumption pattern. The DRM agent receives the first control message, and determines whether the consumption operation detailed in the first control message is a permitted operation. The DRM agent responds with a second control message that either indicates that the operation is permitted or indicates that the operation is not permitted. The rendering application in response to the second control message either halts the consumption operation or if the operation is allowed, performs the consumption operation.

Abstract: A proxy computer of a network can receive incoming telephony messages from one or more computers outside of the network and proxy them to computers within the network. Similarly, the proxy computer can receive outgoing telephony messages from within the network and proxy them to computers outside of the network. To set up inbound calls, a proxy program on the proxy computer looks for the presence of an alias in the call signaling messages, references a data structure to determine which computer on the network is associated with the alias, and proxies the call signaling and control messages between the callee computer and the calling computer based on the association, thereby creating a logical connection between the calling computer and the callee computer.

Abstract: A coating having a gradient composite structure, applied to a substrate, which may be a disposable tool. The gradient composite comprises a bonding component and an erosion and/or corrosion resistant component. When applied to a disposable tool, such as a ball and seat assembly in a downhole environment, the coating enhances the performance of disintegrable materials used in such tools. The coating may be configured to expire at the end of a selected duration, allowing the underlying material to disintegrate.
