Selecting a Database
Price, too is a consideration. With open source, you can test the functionality without an initial investment before opting for a support package. Then, when the decision is made to purchase support, MySQL sweetens the deal by offering the Enterprise package, with some extra functionality just for the paying customer. True, it is new, and has some issues to be worked out, but it is a marvellous concept, and I am curious to see some indication of how well it is selling. As I have stated before, perceived value is an important aspect to some people, the 'bang for the buck' principle, and this new offering caters to that.
Sometimes it is a mindset issue, and I have to say I have been guilty of this at times. It is very easy to move into a new situation and recommend the familiar tools that one is familiar with, even if this means a capital outlay for the new employer. I have done this, and also had this done to me by others, so I can't be too hard on them. Open source requires an open mind in a lot of ways. I see many ingenious solutions to problems. I also see these rejected at times by those of narrow perspective continuing to try to develop solutions in this new environment using guidelines and experience drawn from elsewhere.
Not that experience isn't valuable, but the spirit of innovation must prevail, and a willingness to accept change. Also sometimes one must consider that perhaps the familiar closed-source product has rather bent the standard and changed the rules, so that suddenly finding an environment where these rules are enforced, and with increasing strictness, can be a shock to some. Some complain of this behavior, calling it wrong if familiar code won't execute because it took advantage of an extension previously available.
Sometimes this failure leads to a decision to return to the closed-source world, despite all the good advice on how to adapt.
