DBD2 Concepts

Configuration files:

My (current) development configuration file (/etc/dbd2.conf). It has been edited to remove entries that are no longer valid or that were present for testing (mostly invalid entries to insure error conditions are detected).

Variable Files (varfiles):

A blank 'template-file' for defining SQL-Index Variables. It is a comment-block 'header' (with no file contents). It provides limited 'documentation' and a place to put your sql-variables if you wish to use it. (All DBD2 variables may also be defined in modules if you prefer).
A file that enumerates all possible System-Variables (excluding time-string definitions) that DBD2 currently supports. Provided for your convenience. If you wish to create your own file with your own system-variable names, doing so will not decrease the functionality of DBD2 in any way.
This file (like the SQL-Index file above) contains header comments that I hope will prove useful in defining your own system variables or using those that I've provided.
A file containing header documentation comments for TimeString variable syntax and samples.

Module Files (include(d)-files)

A (working) MySql-database module (dbd.module) to demonstrate the ability to configure 'drag-and-drop' modules that allow for flexibility to move modules between DBD2 applications to balance load or to adjust to corporate 'leasing cycles'. Combining modular configuration with a dedicated IP-address assigned for that module, allows a database service to move from one host to another with its associated IP address) without impacting the network clients that use that service.
A (working) File module (file.module) that I use for testing of DBD2 conversions as I build (and update) them. There may be some templates in this module that are no longer valid due to later configuration changes (some variables may no be longer defined or some variables may have been renamed).
