 ## Databases
+
+The core BixChange system doesn't use a relational database. This, too, is on purpose. If you want to connect to PostgreSQL or MySQL you can simply install and use the popular Class::DBI module and add double quote blocks around anything you want evaluated in a resource (INI) file like this:
+
+

+ 
+      FOO=<<EOF
+          %%
+              use Class::DBI;
+              ...
+              # the following I borrowed from the Class::DBI pod
+ package Music::DBI;
+         use base 'Class::DBI';
+         Music::DBI−>connection('dbi:mysql:dbname', 'username', 'password');
+
+         package Music::Artist;
+         use base 'Music::DBI';
+         Music::Artist−>table('artist');
+         Music::Artist−>columns(All => qw/artistid name/);
+         Music::Artist−>has_many(cds => 'Music::CD');
+         ...
+
+          %%
+      EOF
+ 
+

+ +If our output is a simple string then just make it a stand alone statement like this: + +

+  
+      FOO=<<EOF
+           %%
+                my $n = q|a nice string|;
+                $n;
+           %%
+      EOF
+  
+

+ +Strictly speaking you don't need the last statement but it is highly recommended to avoid confusion later on. If you want to return a bunch of data you can simply use the BixChange::_bankdeposit() method. See /data/m/ma/main11.ini for an example that uses an XObject. +
