Study Notes
- The early days of data processing were dominated by master files, which were stored on magnetic tapes.
- Reading an entire tape could take anywhere from 20-30 minutes, depending on the data and the processing required.
- In the early 1960s, the world of computation consisted of exclusive applications that were executed on master files.
- Experience showed that for a single pass of a magnetic tape that scanned 100% of the records, only 5% of the records, sometimes even less were actually required.
- DSS processing as we know it today has reached this point after a long and complex evolution.
