windows phone 7 - Making offline database application on WP7 - find the right way -

-

i need build offline database application on wp7. app simple - it's making orders our clients, translate main server (ms sql).

spend days read existing techologies - i'am still confused. right project?

  1. sync framework. looking good, understand - provides single tables - no reference beetwen them. references have build on client side. sad.

  2. entity framework on server side. , have no clue - can use on client side. there way serialize entity object isolate store, restore it, , continue work it? may can use sync framework, scheme become strange - kinda 1 way.)))

  3. working wcf & xml - simple me. lot of code , conversion, in case understand data flow. in other view - have app pure sql-queries. wanna advanced. ))))

  4. using ext. databases (siaqodb example). one? siaqodb suppots "sync provider", doesn't support references beetwen objects - have build them myself? gain? don't know.

is there way build such apps? point please.

if has done offline, use like:

  • storing minimal amount of required data within isolated using wp7 specific database sterling
  • using either new rest or new ria/wcf service objects/functions define in order provide required data synchronisation

i think option 3?

i've never liked automatic data synchronisation. find easier code sync , deal error cases myself - case if wp7 client app uses quite small footprint of data in relation larger main server db.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875
