ideal situation is centralised server with ideal connectivity memang betul distributed perlukan server, maintenance, training, deployment untuk setiap site. no harm in comparing the pros and cons between the many options. the more important thing is to consider all options / possibilities. kongsi sikit pengalaman implement epbt di terengganu : epbt ada 2 main systems (client server and web app) 1. main database and client app for all functions and counter services : which is local to the pbt hq 2. client app for all functions and counter services at branches with vpn connection to main database at the pbt hq 3. client app for selected services which can be done offline (example payment and issue of licenses at public places where there is no connection) 4. web app for customer services (statement / payment) with daily uploading via vpn between pbt hq and state govt, with customer accessing through the internet mixed between centralised and distributed according to the situation decentralised actually requires a more complex and comprehensive design, but it is actually practical if you only need to upload reporting data. i have seen general electric and honeywell offices in malaysia using local installation of software, then uploading the data on daily basis to the centralised global sap system. it becomes necessary for high volume counter services at branches like for banks or touch and go terminals. for banks even with leased lines, a distributed layer still exists, so that some services can still be performed (boleh terima duit tapi tak boleh buat withdrawal) # tengah boring tunggu processing 60 million transactions from all the tng toll terminals : berhari - hari .... 2011/3/15 Sharuzzaman Ahmat Raslan <sharuzza...@gmail.com> > sistem macam ni lebih tak reliable, berbanding menggunakan satu server > > dan juga sistem macam ni memerlukan lebih banyak hardware, dan lebih banyak > kos. maintenance pun kena kira juga. > > > > > On Tue, Mar 15, 2011 at 2:39 PM, cikgu ayob <ayob.alham...@gmail.com>wrote: > >> Assalamualaikum....kawan2.... >> ramai juga yang memberi pandangan.. >> saya pun bersetuju...kita gunakan...isi markah on local network.. >> then...push the data to the system.. >> >> kawan2 macam mana? >> >> -- >> To unsubscribe from and detail about this group >> http://portal.mosc.my/osdc-my-mailing-list-information >> >> MOSC2011 http://fb.me/mosc2011 >> > > > > -- > Sharuzzaman Ahmat Raslan > > -- > To unsubscribe from and detail about this group > http://portal.mosc.my/osdc-my-mailing-list-information > > MOSC2011 http://fb.me/mosc2011 > -- To unsubscribe from and detail about this group http://portal.mosc.my/osdc-my-mailing-list-information MOSC2011 http://fb.me/mosc2011
