Normally, dApp gets instantiated from the client app's main Python
script,
and lives through the life of the application.
- -- set up an empty data connections object which holds
- -- connectInfo objects connected to pretty names. If there

there

+ -- Set up an empty data connections dict that contains
connection objects
+ -- that use descriptive names as their keys. Obviously this
requires that
+ -- each connection has a unique name; if you create connections
with
+ -- identical names, the second one read in will overwrite the
first, and
+ -- the results are not guaranteed. Once read in, the only
identifier for a
+ -- connection is its name; the file from which it was read in,
if any, is
+ -- irrelevant. Any .cnxml files found in the app home
directory, the
+ -- current directory (if different) or any subdirectory named
'db' or
+ -- 'data' of the home/current directory will be automatically
read into the
+ -- connections dict, but the connections aren't made until
requested by the
+ -- app. Additionally, connections defined in Python code in a
file named
+ -- 'dbConnectionDefs.py' will be imported. This is an old
behavior that
+ -- should no longer be used.
-- Set up a DB Connection manager, that is basically a
dictionary
-- of dConnection objects. This allows connections to be shared
