I 100% agree with all those saying, "get a real database" for your application.
I'd actually go one step further and say, "get a real OPEN SOURCE database".
There are a number of excellent open source database products in widespread use that you could choose from. Unless you have very unusual or unique technical requirements, there is NO REASON whatsoever to pay for database software these days.
The most popular open source database is of course MySQL, see
