Big Database (Part 1): Scalability
Despite multiple challenger technologies (i.e. object-oriented databases), the relational databases from Oracle, IBM, and Microsoft have prevailed supreme for over 30 years.
This dominance has, however, been increasingly challenged by a new wave of technology solutions that started with database appliances from Teradata and Nettezza driven by big data requirements. This was followed by open-source NoSQL databases including HBase and Cassandra. Development continued with NewSQL databases including VoltDB and MemSQL, and finally, although not a database, Hadoop HDFS is providing a significant competition as a potential data store.
