I do a lot of different things and it is hard to keep up with it all.
So forgive me for having a little brain hickup with this one, but I
just want to verify that I understand this correctly.
If I create a DAO in application scope, could I use the same DAO for
CRUD operations on all records being access by different sessions?
For example, does anyone see a problem with doing this?
At application startup call this in application.cfm:
application.dao = createObject("component","some.dao");
session 1 might call something like this:
dao.read(session.record);
session 2 might call something like this:
dao.update(session.record);
session 3 might call something like this:
dao.read(session.record);
session.record could be a structure or bean or something like that.
All of these calls may occur at the same time. Does anyone see any
problems of all sessions using the same dao instance?
The reason, I am asking is because I would like to create a factory
that would create one instance of some objects like a dao, gateway,
logger, etc. and seperate instances for other type of objects like
user, record, useraddress, other beans, etc.
