DataStax, which helps companies deal with the vast troves of data scattered around the Internet, said it had raised $106 million, further enabling it take on incumbents such as Oracle Corp and Microsoft Corp . DataStax uses a technology known as Apache Cassandra, one of a new breed of so-called NoSQL databases that offer more flexibility than traditional databases. Traditional incumbents include Oracle’s MySQL, Microsoft’s SQL Server and IBM’s DB2. “Cassandra, from the day it was created, was built to withstand unbelievable amounts of failure in the underlying system and still be available,” said Billy Bosworth, DataStax’s chief executive officer.
