Document Summary

Computer companies have developed computers with very large memories for in-memory processing. In-memory processing doesn"t have etl (extract, transform, load), it has multiple processors, it enables to handle large volumes of data and able to provide fast answers. Traditional bi technology loads data onto the disk in the form of tables & multi-dimensional cubes against which queries are run. Give examples of drill down questions that you would ask using r, f and m. E. g. the number of months that have passed since the customer last purchased. Rfm is a method used for analyzing customer value: describe the differences between online real time processing (oltp) and end of period processing. When using a pms, give examples of when oltp would be used and when end of period processing would make more sense. Oltp system deals with operational data, in the system. Tps: data are frequently updated & queried, therefore, quick response to a request is highly expected.
