I am working in a trading applications that depends on an Oracle DB.

The DB is crashed two times and the business owner wants some solution in which the application still works even the DB is crashed.

My team leader introduced Cassandra NOSQL as a solution as it has no single point of failure but this option will make us move from the traditional relational model into the NOSQL model which I consider as a drawback.

My question here, Is there a way to avoid a single point of DB failure with traditional relational DBMS like Mysql, postgreSQL,……etc ?
