Hello to anybody and anticipately thanks to the ones who would help me
to understand in a summary and generic way what is the difference
between mysql and mysql cluster. what does it mean that mysql cluster
is a 'real time' DB?

MySQL Cluster aka NDB aka NDBCluster is a storage engine for MySQL.
Unlike traditional storage engines, NDB is not linked into the mysqld
process, but runs as a bunch of distributed processes (ndbd, ndb_mgmd)
in the network.

NDB implements a noSQL interface called NDBAPI. The MySQL server
(in cluster speak: SQL node) "translates" SQL to NDBAPI and thus makes
the cluster look like an ordinary DBMS. There can be multiple SQL nodes
in the cluster. And applications can connect directly.

It's a database suitable for real-time computing
