Caption: FIGURE 8: The file writing time in sequential access
In SCAN or second phase (steps from 2b to 2c), it verifies if final object's scores are not duplicate; then, it executes a sequential access
for each list [S.
The high costs for the unpartitioned is mainly due to sequential access
costs (772 ms for proposed design vs.
As discussed previously, COBOL has a much better ratio for sequential access
than the fastest 4GL (2:3).
The hardware cache, by default, is geared to expect sequential access
so it is able to prefetch the next block of a file before the user program ever requests it.
Support for larger file sizes - more than nine billion gigabytes - and up to a 50 percent performance boost from an enhanced, 100 percent Java-based indexed sequential access
method (ISAM) file system in isCOBOL JISAM
Though automation resolved many troublesome issues regarding removable media storage, the time to recover data from tape and the fact that tape only enables sequential access
remain as obstacles for some applications.
Advantage is unique among the Sybase database offerings in that it provides both Indexed Sequential Access
Method (ISAM) table-based and SQL-based data access, providing a growth path for legacy database applications to today's modern techniques.
The slow seek time, throughput performance, media characteristics and sequential access
nature of tapes and tape drives causes complexity, unreliability and limitations within existing backup systems.
Random and sequential access
required based on the application
The IDT flow-control management devices combine critical functions such as high-speed buffering, switching, multiplexing/de-multiplexing, domain transition and random and sequential access
If the application requires sequential access
to data, these SATA RAID sets would provide a raw data rate that is comparable with enterprise drives.
