  =head1 DESCRIPTION
- Data::Storage is a module for accessing various "data structures" stored inside
+ =head2 Data::Storage
- various "data containers". It sits on top of DBI and/or Tangram.
+   Data::Storage is a module for accessing various "data structures / kinds of structured data" stored inside
+   various "data containers".
+   We tried to use the AdapterPattern (http://c2.com/cgi/wiki?AdapterPattern) to implement a wrapper-layer
+   around core CPAN modules (Tangram, DBI).
+ =head2 Why?
+   You will get a better code-structure (not bad for later maintenance) in growing Perl code projects,
+   especially when using multiple database connections at the same time.
+   You will be able to switch between different _kinds_ of implementations used for storing data.
+   Your code will use the very same API to access these storage layers.
+       ... implementation has to be changed for now
+   Maybe you will be able to switch "on-the-fly" without changing any bits in code in the future....
+       ... but that's not the focus
