1. A federated system for supporting an application to perform analytics, the federated system comprising: a first distributed system for performing one or more first tasks including processing incoming data into a set of data blocks; an in-memory database system for performing one or more second tasks including receiving the set of data blocks from the first distributed system and storing the set of data blocks in an internal storage; and a second distributed system for performing one or more third tasks including receiving at least one data block of the set of data blocks stored in the internal storage of the in-memory database system and performing analytical calculations on the at least one data block, wherein execution of the first, second, and third tasks on the first distributed system, the in-memory database system, and the second distributed system are controlled via executable instructions of a scripting language utilized by the application, the scripting language being a main language of the in-memory database system, wherein the one or more second tasks includes receiving results of the analytical calculations from the second distributed system and storing the results in the internal storage of the in-memory database system, wherein the in-memory database system is configured to parse the executable instructions to obtain script associated with the second distributed system, the script associated with the second distributed system having been embedded within the executable instructions, the in-memory database system configured to transmit the script associated with the second distributed system to the second distribution system for performing the analytical calculations.
