Why choose Oracle?
Oracle Database Tips by Donald Burleson
Choosing the best database product - Why Oracle?
?Why Oracle?? This was the question that everyone asked
when Oracle was displacing the mainframe DB2 systems back in the early 1990's.
Back then, Oracle had carved-out a niche has being a versatile database, not
constrained as DB2 was to MVS and Informix is to UNIX. At the time, I was
charged with making a ?buy? decision for the new ?mini computer? databases, and
I?ve been intimately involved in this question for decades.
Oracle is the not the most elegant database, and it's
not always the fastest platform. Oracle rose to the pinnacle of the IT world on
other virtues. Rather than wait for the end-user community to react to market
changes, Oracle took a proactive approach and often introduced features
far-ahead of the market demand. I remember when Oracle 7 was undergoing beta
testing and we wondered about the new ?cost based optimizer,? ?hash joins,? and
bitmap indexes. In Oracle 8, we replaced EBU with RMAN and learned about
partitioning and star transformations. And so on?high anticipation with every
Oracle Dedication to enhancements
OpenWorld 2006, Oracle announced some exciting new features of Oracle 11g
and they promise a mind-boggling 482 of them, some minor and some
profound, including rolling upgrades, query
results caching, and capture and replay of database workloads.
It's not a random event that Oracle dominates the world's database market and
runs on over 60 platforms, everything from a Mainframe to a Mac.
Oracle does have many competitors in the marketplace,
ready to pounce on any perceived weakness. We see these arguments from Oracle
have to make a ?buy? decision for database software, they just go with the
market leader. Isn't that enough rationale?
Oracle is expensive?hey,
you get what you pay for. Plus, Oracle now has the free Oracle XE to compete
Oracle is too complex?Complexity
is the natural byproduct of being robust and flexible. However Oracle
addresses this issue with automated memory and storage management. Beginning
with 11g, Oracle's Automatic Storage Management (ASM) will enable a
single storage pool to be shared by multiple databases for optimal load
balancing. Also in 11g, all memory can be tuned automatically by
setting one parameter. You literally tell Oracle how much memory it can use
and it determines how much to use for PGA as well as SGA.
