Hello !!

I've begun with MySQL in 1995. The applications used were: web, but many
databases made for Nuclear Labs, Télécom Labs, Research Labs.

When MySQL 3.23 and 4.x arrived, some big market actors industries
(cars, army, nuclear, pharmaticals, medical, finance and so on,..) have
adopted this new database for prices, performances, simply to use.

With MySQL 5.x, it's revolution. This BDD is on top and is concurrent
with MS, Oracle, Sybase ....

MySQL is provided with commercial (MySQL Enterprise) or no commercial
(MySQL Community).

MySQL can be use for for heavy-weight, highly secure, applications, like
financial and/or medical applications, nuclear, spacial, aeronautics,
embedded in noteads, pdas, smartphones, .... Some characteristics are
replication, cluster, scalability, ..., business intelligence.

For Telecom industries, it's a really business: in all new Alcatel PABX,
MySQL is present with an OS named BSD (embedded licences is a very
good thing for them, with volume). See case Utel Telecom.

And the future version 6.0 with Falcon Engine and Maria Engine (code
name), it will be a very good product.

Postgresql is not on the same line. This BDD is an Oracle like. So, most
heavy, less known but solid too.
