Transaction design strategies for MongoDB, Cassandra, and HBase NoSQL databases (such as MongoDB, Cassandra, Hbase, DynamoDB, and Riak) make application development easier. They provide quite flexible data models and rich data types, and are easier to install and configure than many traditional database systems. However, the lack of support for atomic transactions is a major step backwards. Daniel Abadi is an Associate Professor at Yale University and
