|
|
64 |
|
- should encapsulate Tangram, DBI, DBD::CSV and LWP:: to access them in an unordinary (more convenient) way ;) |
65 |
|
- introduce a generic layered structure, refactor *SUBLAYER*-stuff, make (e.g.) this possible: |
66 |
|
Perl Data::Storage[DBD::CSV] -> Perl LWP:: -> Internet HTTP/FTP/* -> Host Daemon -> csv-file |
67 |
|
- provide generic synchronization mechanisms across arbitrary/multiple storages based on ident/checksum |
68 |
|
maybe it's possible to have schema-, structural- and semantical modifications synchronized??? |

=head1 DESCRIPTION |
=head1 DESCRIPTION |
429 |
|
|
430 |
Data::Storage is module for a accessing various "data structures" stored inside |
=head2 Data::Storage |
|
various "data containers". It sits on top of DBI and/or Tangram. |
|
431 |
|
|
432 |
|
Data::Storage is a module for accessing various "data structures / kinds of structured data" stored inside |
433 |
|
various "data containers". |
434 |
|
We tried to use the AdapterPattern (http://c2.com/cgi/wiki?AdapterPattern) to implement a wrapper-layer |
435 |
|
around core CPAN modules (Tangram, DBI). |
436 |
|
|
437 |
|
=head2 Why? |
438 |
|
|
439 |
|
You will get a better code-structure (not bad for later maintenance) in growing Perl code projects, |
440 |
|
especially when using multiple database connections at the same time. |
441 |
|
You will be able to switch between different _kinds_ of implementations used for storing data. |
442 |
|
Your code will use the very same API to access these storage layers. |
443 |
|
... implementation has to be changed for now |
444 |
|
Maybe you will be able to switch "on-the-fly" without changing any bits in code in the future.... |
445 |
|
... but that's not the focus |
446 |
|
|

524 |
- Add some more handlers: |
- Add support for some more handlers/locators to be able to |
525 |
- look at DBD::CSV, Text::CSV, XML::CSV, XML::Excel |
access the following standards/protocols/interfaces/programs/apis transparently: |
526 |
- Add some more locations/locators: |
+ DBD::CSV (via Data::Storage::Handler::DBI) |
527 |
- PerlDAV: http://www.webdav.org/perldav/ |
(-) Text::CSV, XML::CSV, XML::Excel |
528 |
- Move to t3, use InCASE |
- MAPI |
529 |
|
- LDAP |
530 |
|
- DAV (look at PerlDAV: http://www.webdav.org/perldav/) |
531 |
|
- Mbox (use formail for seperating/splitting entries/nodes) |
532 |
|
- Cyrus (cyrdeliver - what about cyrretrieve (export)???) |
533 |
|
- use File::DiffTree, use File::Compare |
534 |
|
- Hibernate |
535 |
|
- "Win32::UserAccountDb" |
536 |
|
- "*nix::UserAccountDb" |
537 |
|
- .wab - files (Windows Address Book) |
538 |
|
- .pst - files (Outlook Post Storage?) |
539 |
|
- XML (e.g. via XML::Simple?) |
540 |
|
- Move to t3, look at InCASE |
541 |
|
- some kind of security layer for methods/objects |
542 |
|
- acls (stored via tangram/ldap?) for functions, methods and objects (entity- & data!?) |
543 |
|
- where are the hooks needed then? |
544 |
|
- is Data::Storage & Co. okay, or do we have to touch the innards of DBI and/or Tangram? |
545 |
|
- an attempt to start could be: |
546 |
|
- 'sub getACLByObjectId($id, $context)' |
547 |
|
- 'sub getACLByMethodname($id, $context)' |
548 |
|
- 'sub getACLByName($id, $context)' |
549 |
|
( would require a kinda registry to look up these very names pointing to arbitrary locations (code, data, ...) ) |
