Video demonstrates rapid PostgreSQL database development by using RCD Notes & Hyperscope for GNU Emacs. Decision has been made to modify the Hyperdocument table "hyobjects" and use available column to become foreign key for the Hyperdocument sharing types. One may see that new table has been created within few seconds designating Hyperdocument sharing types. Triggers to update modification timestamps and user names who modified it have been added by using key bindings. New table view has been added semi-automatically. New entry has been added. Columns have got descriptions. Entries have been added to say how to share Hyperdocument.

I was thinking that sometimes it may be necessary to audibly hear the name of the Hyperdocument. That is alright, when we speak in a meeting, and multiple people are in the same room.

This video demonstrates implementation of Emacs Lisp function that will speak the name of the Hyperdocument. Audio has not been recorded.

The video demonstrates how to add new database columns visually, just by pressing "A" to some database table. In this case I have added "UUID" column.

Video demonstrates user definable tag types and opening of Hyperdocuments by tag, by using moue, in RCD Notes & Hyperscope for GNU Emacs, The Dynamic Knowledge Repository as devised by Doug Engelbart.

Video demonstrates the fundamental database of relations, Semantic Triplets, being visually edited in GNU Emacs while using RCD Notes & Hyperscope for GNU Emacs, The Dynamic Knowledge Repository as devised by Doug Engelbart.

Implementation of Semantic Triplets in PostgreSQL database:

Programming Emacs visually with semantic triplets:

Video demonstrates visual editing of Semantic Triplets in the RCD Notes & Hyperscope for GNU Emacs, The Dynamic Knowledge Repository as devised by Doug Engelbart.

Video demonstrates opening of PDF files at specific page. This means:

Video demonstrates that it may be very easy to add database based properties to any elementary object in the Hyperscope for GNU Emacs, The Dynamic Knowledge Repository as devised by Doug Engelbart.

Video demonstrates embedding of Emacs Lisp in any kind of text documents by using the RCD Template Interpolation System for Emacs. Embedded document may have programming code such as setting up variables, or returning strings, and thus may dynamically create the content of the document.
