View as plain text  
Hi Kevin,


> I'm a system administrator for a small (200 people) branch of a large
university/medical school. I've worked with MySQL and use it as my database
of choice for web-based dynamic content. I would not consider myself an
experienced, professionally-trained, knowledgeable database administrator,
more of a database user who's had to administer his own database systems
because no one else's around.

database work within our organization. The one professional database
administrator we have works mainly in MS Access, but is looking forward to
building on her beginner-level understanding of SQL and becoming an SQL
administrator. Right now, the largest database in our organization is a
flat-file structure with less than 500,000 records in it, which could
conceivably grow ten-fold in the next five years. The organization hired an
outside consultant to evaluate which SQL engine to go with. This is what he
sent to us:

I feel out of my depth evaluating this comparison.

Referential integrity is supported for "InnoDB" type tables - with MySQL,
each table can
have a different type, each table handler (in the MySQL system) can handle
different
features. With InnoDB, there's Referential integrity, transaction support
and and also
a different locking  mechanism - which is more suited for lots of readers
and concurrent
writers.

Fairly fair :-)

Triggers, views and Stored Procedures are expected to be included in MySQL
5.

The next version of MSSQL will include a new locktype/transaction isolation,
one which works pretty much the same as InnoDB -> versioned locking.

If it's not "very sophisticated", MySQL will do just fine. In my opinion.
There are
other free and open source DBMSes as well, that do have procedures,
triggers,
views, subqueries and the like.
