After over a month of the solution being live it is no doubt all went as planned, and with no major surprise. Even if we expected the new HANA solution to be faster, especially in the segmentation area, we can understand that terabytes of data can be hard get immediate response for any system. We improved it, however, by setting up the HANA db index (similar to outdated TREX solution), which reduced responses from minutes in some complex cases, to a matter of up to a few seconds for each of them. Combined with the data flexibility and extensibility of the tools that the business users have now, it is possible to execute marketing operations by one person in one day for much bigger data volume and with more complex algorithms – comparing to days before the implementation when a few employees in a few weeks were preparing similar workload with much less sophisticated analyses or requirements possible.
