Data Retrieval, Processing and Final Storage in the Nile Basin Database
Detailed Outline of Data Trajectory
thereafter to transfer/upload the raw data to the Personal Computer at the office. Information is stored in the module
in a specific format, which cannot be read directly by IBM compatible PCs.
The role of the SC532A or SC932 Interface is, therefore, to convert this specific storage module format into a RS232 compatible
information communication standard, which is ‘understood’ by IBM compatible PCs.
Data can also be downloaded directly from the meteorological station to the PC using short haul modems without using key-
board and storage module.
Data pre-processing, processing final check and storage in the NBD is accomplished on PC.
2.3 Software
Figure 2 presents the various software packages and programs, as well as the concerned file formats, which are
used in the process of data acquisition, pre-processing, processing and final storage.
Data processing, rearrangement and final storage in the LVBD is accomplished on PC.
