摘要： Techniques for replicating data in a system having a data tier with a plurality of data sources and an application tier with a plurality of applications are provided. Such techniques can include creating an instance of an information model of the data that is specified by a schema. The model can be created in a form that is suitable for manipulation by at least one of the applications and that forms at least a portion of a model tier that is intermediate the data tier and the application tier. A replica of an instance of the information model can be created in a form suitable for remote transmission, and a consistency policy can be obtained that specifies a level of consistency required between the instance of the information model and the replica.
摘要翻译：提供了在具有多个数据源的数据层和具有多个应用的应用层的系统中复制数据的技术。这样的技术可以包括创建由模式指定的数据的信息模型的实例。该模型可以以适合于由至少一个应用程序操纵的形式来创建，并且形成在数据层和应用层之间的模型层的至少一部分。可以以适于远程传输的形式创建信息模型的实例的副本，并且可以获得指定信息模型的实例与副本之间所需的一致性级别的一致性策略。

摘要： A method, system, and apparatus for handing-off data receivers in a broadcast-based data dissemination environment. Data receiver hand-off is carried out between data sources in different data cells broadcasting information of the same category. Furthermore, data cell ranges are based on geographic regions rather than signal strength coverage. Generally, the hand-off process involves acquiring the current receiver location of the data receiver and comparing the receiver location with a current data cell range. If the current receiver location is outside the current data cell range, a hand-off controller searches for a new data source encompassing the current receiver location coordinates and having an associated data topic matching the current topic. Once a new data source is found, the hand-off controller subscribes the data receiver to the new data source.
