JDB: Layout Columns | Queries Σ | API: Structural Records | Client/Server | Implementation | Examples
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.
