    Abstract: There are provided systems and methods to respond to a request for data. The system receives a request to search for the data based on a criterion and to populate data objects with the data. The request is further used to identify columns that determine data sources to query. The system performs a search of a logical table based on the criterion to identify a plurality of rows in the logical table. The system further generates a first plurality of tuples based on the plurality of rows to identify a first plurality of physical tables that are mapped to the logical table. The first plurality of tuples includes a first tuple and a second tuple. The system further queries the data sources for the data to generate results by using the first plurality of tuples. The queries of the data sources are partially successful.

    Abstract translation: 提供了响应数据请求的系统和方法。 系统接收到一个基于标准搜索数据的请求,并用数据填充数据对象。 该请求进一步用于标识确定要查询的数据源的列。 系统基于标准来执行对逻辑表的搜索,以标识逻辑表中的多个行。 系统还基于多个行生成第一多个元组,以标识映射到逻辑表的第一多个物理表。 第一组元组包括第一元组和第二元组。 该系统还通过使用第一组多个元组来查询数据源以获得数据以产生结果。 数据源的查询部分成功。
