High Speed
File Import Speeds Flat ASCII Files |
| Seven thousand records
per second race when compared to three thousand records per
minute. Import of files into the Unibase by DMAC release 7.48i has
achieved this improvement. This speed change comes at the expense of two
features -- the file must be exclusively accessed and no added fields or
packed decimal fields are allowed.
The speed of the workstation, the amount of RAM, the speed of the disk and the network topology also affect actual speeds. The command line spawned executable program name is rawdata. The MUI (Menu User Interface) is under Advanced Processing, File Input/Output Functions, then "Read Flat ASCII One Format file." The prior slower, but more feature rich capabilities, still exist. A new, faster way has simply been added. These changes are part of the DMAC effort to speed up Microsoft operating systems by taking more of the operating system functions into the Unibase Environment. Resting lightly on top of the operating system gives this speed improvement. |
