IBM DB2 database universal

I suggest everyone to use IBM DB2 database universal, for storing data and create data tables or store any kind  of data, the connectivity is very good and it has so much security..the best software most of the companies use to store data and make changes related to the project code

Does it cost? or is it free

Its a licensed soft ware we neeed to buy, no way to get for free..there are many server we can run using this..

I use MySQL
