摘要
Systems and methods for performing a query using abstracted metadata are described. As described, a metadata object that requests data from a plurality of data sources can be received from, for example, a user device. One or more queries for the one or more of the plurality of data sources based upon the metadata object can be generated. The queries can then be transmitted to the one or more data sources. Results of the queries, according to the method, can be stored in a block memory. In various embodiments, the metadata object may be user-generated and define one or more of a data source, filter conditions, sorting conditions, aggregations criteria, and an operation. Additionally, various embodiments describe updating the queries at pre-determined intervals which can be defined by the metadata object.
