Home -> Community -> Mailing Lists -> Oracle-L -> Re: MySQL vs. Oracle database
By default MySQL has no transactions
You have to add special component to access "transactional safe tables"
called Berkeley db tables. You can commit and rollback on only these
tables. For others every wrong (not syntactically, but for example
inserting characters into number column) insert and update will succeed. If
MySQL cannot insert provided values it uses default values.
One of the biggest pains is (maybe was, I don't know about MySQL 4.xxx) that it has no foreign keys :((((((((((((
I have created class diagramms for both Oracle and Mysql servers for my
studies in University. It cannot be treated as feature comparison but just
simple overview of these two images will show the situation i.e. compare
object count on these images :-)
And I have to say that Oracle diagramm isn't complete!

Please respond to
ORACLE-L
I have not been so much with MySQL , But want to share my experience.
Firstly , it is very fast ...This makes me suspicious , I wonder if it is
trusted to be integral .
Seem like no control ..Does not contain rollbacks , may be this .. Then how
does it rollback ?
I have used a version where stored procs ,functions are unavailable .. Wonder if it has now..

The degree of normality in a database
is inversely proportional to that of its DBA.
