Competitive Analysis –<br />
Hardware Based Compression<br />
<strong>Oracle</strong><br />
<strong>Database</strong> specific compression<br />
algorithm<br />
Fine grained compression –<br />
compress at tablespace, table or<br />
partition level<br />
Improved read performance in<br />
several cases – no<br />
decompression overhead<br />
Improved memory efficiency -<br />
data stays compressed in<br />
memory<br />
Batched algorithm for minimal<br />
compression overhead<br />
Benefits automatically cascade to<br />
all environments<br />
Hardware Compression<br />
Generic compression algorithm -<br />
deficient for databases<br />
No fine grained compression -<br />
compress at file level<br />
Poor read performance –<br />
significant decompression<br />
overhead<br />
No memory benefits - data needs<br />
to be decompressed<br />
Data updates are very expensive<br />
Benefits limited to specific<br />
hardware environment
