The tables.vmd is used with db.tables{} to create a tables node tree, for use with the conn:merge{} function.

The tables.vmd contains an example table structure, you will need to modify it to match your own database tables. See Creating the tables.vmd file using Chameleon to understand how we created it (then follow the same steps to create your own vmd).

How to use the tables.vmd:

• Use the VMD with db.tables{} to create a tables node tree
• Add data to the node tree (frequently mapped from an HL7 message)
• Use the node tree with conn:merge{} to write to the database

See the Basic syntax example using db.tables{} and db conn merge{} for more information.
