1. A data processing system, comprising:

  • a relational database for storage of transaction data;

    an OLAP database for storage of a replication of the transaction data in an OLAP cube;

    means for storing data indicative of a replication time;

    a random access memory;

    means for receiving a data request, the data request specifying at least a first time interval;

    means for reading OLAP cube data from the OLAP cube;

    means for storing the OLAP cube data in the random access memory;

    means for determining the replication time using the data indicative of the replication time;

    means for generating a query for the relational database specifying a second time interval, the second time interval having a lower limit given by the replication time and an upper limit given by the upper limit of the first time interval;

    means for receiving replication data from the relational database in response to the query;

    means for storing the replication data in the random access memory; and

    means for generating an output using the OLAP cube data and the replication data stored in the random access memory.
