Suresh, The real question is:  does manipulation of the images have to be transactional?  If so, store them in the database.  If not, store the images in the file system and put the file name in the database, thereby avoiding unecessary WAL overhead. Bob Lunney --- On Wed, 4/7/10, Suresh Borse

Timothy, I've worked with SQL Anywhere which does have database encryption. There are pluses to having a encrypted db, but it did slow down the processing. They also had the ability to encrypt stored procedures and triggers. That didn't' seem to really slow down the system. That being said, th
