Rebol Programming/Language Features/Database
Rebol/Command, Rebol Technologies enterprise product, is the only version that comes with database abilities out of the box. This includes support for Oracle, ODBC, and MySql. It is the stated intention of Rebol Technologies to release the source code for the database protocols, but in the meantime third party developers have written interfaces for the free Rebol/Core to some of the more popular database products.
In many instances, the database adaptor has been written as a Rebol protocol, and access to the database is via a virtual port. Database queries are then inserted ( sent ) into the port, and results are retrieved by reading from the port.
