Re: [gentoo-server] ldap or mysql?

[Linux]

HI

I think it boils down to the product that you really know and is used to.

I'm for example, is working at a telco where we prefer oracle, it is expensive 
yes, but it fullfills our needs of functionality, scalability and performance 
as well as we (internally) know the product very good.

I think the same goes for mysql/postgresql, which product you're using is (for 
a major company) not that interesting but the benefits/costs are.

That means does the product deliver what's needed and does their support 
really jump to our needs and problems? That's the basic problem we got, 
Oracle do, are not open source, and not free in terms of cost......

MySql and PostgrSQL are not free when it boils down to 24x7 support 
either.....

It's all about business, what it's worth to you, and what you can afford...

Personally by the way, I'm using mysql..... basic stuff, really don't know the 
cores of it
