Info Area: SAILOR_WEAR_00 This cube has five dimensions with three navigation attributes, which can be seen from star schema. Additional it should have key figures according to data file. The dimension organisation has a hierarchy, which will be retrieved from the master data. It is not time-dependent. The dimension time should have following characteristics. Characteristic: Characteristic: Characteristic: Characteristic: 0CALDAY 0CALMONTH 0CALQUARTER 0CALYEAR Any further required information can be extracted from data file structure. The source system and application component should be named as follows. The data will be manually imported from a flat file system. The info sources shall have the same notation as the info objects. The transfer data shall be directly imported into the data warehouse. The sequence of transfer data can be reviewed in flat file. Data flow can be seen in figure 3.
