Which database, there is MySQL, PostgreSQL, MSAccess, XML, OracleDB, CSQL... Some more information at Wikipedia - http://en.wikipedia.org/wiki/Database Code (markup):
I prefer more MS SQL which is almost the same with MySQL,, same with logic,condition and just a few difference with its syntax Anyway, database is different from relational database,. and MYsql and MS SQL are RDBMS
