In some embodiments, a computer system is described. In some embodiments, the computer system receives, from a client application, a first request to access a collection of applications associated with an operation, wherein the collection of applications is associated with at least one third-party entity. In some embodiments, the computer system receives a selection of an application associated with a third-party entity from the collection of applications. In some embodiments, in response to receiving the selection, the computer system identifies a set of data comprising an aggregation of data stored on a plurality of databases required to perform the operation associated with the application. In some embodiments, the computer system determines that the application has access to the aggregation of data. In some embodiments, the computer sends a request to perform the operation to the application. In some embodiments, the computer system receives a set of results based on the performance of the operation.
