InnoDB vs MyISAM

[Octavian Rasnita]

Hi,

I have seen that by default some tables are created as InnoDB and some as 
MyISAM.

I guess the table type is not chosen randomly. How is it chosen the table 
engine used?

And is InnoDB recommended now?

Does it support full text indexes? Or if not, is there a way of using full 
text indexes and foreign keys in MySQL?

Thank you very much.
