The Lisbon MongoDB User Group is a place for developers to learn more about the non-relational, open source, document-oriented database MongoDB. MongoDB is the leading NoSQL database and many of the key committers often travel to Europe. So if you are facing challenges with MySQL, Postgres or Oracle, and would like to explore a more flexible, scalable alternative, please join us at one of our friendly, monthly sessions in Lisbon.

The Apache Cassandra Project develops a highly scalable second-generation distributed database, bringing together Dynamo's fully distributed design and Bigtable's ColumnFamily-based data model. The Lisbon Apache Cassandra User Group is a highly awesome meetup group, bringing together cool people distributed across Lisbon to talk about our favorite NoSQL implementation, Apache Cassandra.
