In addition to SQL, NuoDB supports Java stored procedures, triggers, and user defined functions (UDF). The Java API supported by stored procedures, triggers, and user defined functions is referred to as the NuoDB embedded Java API and it is important to note differences between the NuoDB JDBC Driver API and the NuoDB embedded Java API. See Unsupported Methods in Embedded Java API for more information.
