JDB

JDB is a database where columns are mapped J nouns. Compared to a traditional RDBMS:

• it is straightforward to read/write data from J
• a task can add new records very efficiently by simply appending to the mapped nouns
• record searches are very fast on large amounts of data

For an overview and summary of features, see JDB announcement.
