First, why doesn't the consultant think that Oracle locks records? Is he complaining that in Oracle that writers and readers do not block each other? Is he complaining that an individual query in Oracle is read consistent? Is he complaining about the concept of a transaction? Why not ask him what relational databases he has worked with in the past?

There is pretty good empirical evidence that Oracle works in serious multi-user environments.

We have a consultant at our shop who is convinced that Oracle is inadequate for a serious multi-user environment because of the lack of record locking and dynamic result sets. We have been using it to develop and deploy a OLTP system and haven't found any serious problems that could not be addressed.

The dynamic result set that he has mentioned has me a little puzzled. He is stating that relational databases that he has worked with in the past returned a result set to him for use in his apps that would change dynamically if another user changed one of the records that he was displaying. I'm a relative newcomer to the database arena, 2 years, but this is something new. I've been told by another developer that Access will do this, but he hadn't heard of any serious systems that do.

Has anyone else heard of databases that perform that function?

Any suggestions on resources related to record locking in Oracle? We have two other developers that have worked with it extensively in the past, but the consultant is convinced that he knows differently, so we do need some solid research to refute him.
