mobile - Need architecture idea for POS -

me , team developing pos system restaurant chain.

in addition windows application pos, main idea make native (not html5) mobile application in tracking orders.

the mobile app should -
1. waiters take , track order.
2. manager should able check employees's leaves,timings,etc.

on pos part -
thinking make particular restaurant work local database synced central database.

are on right track? can html5 in mobile application?

how many willing pay me give architecture? kidding.

think of retailer that:

• has 10 kind of items
• with sell 5 quantity of each items each day
• that has 1 staff , his/her family
• that sell cash , not electronic payments

do think kind of retailer need mobile application can pos cloud computing support? of course not. he/she maybe need book written manually simple accounting debit credit track his/her income/expense. big company w*lmart do.

if want make application, make sure has requirement. why bother create not needed?

if want make general pos application, collect basic requirement first. need. input entering item code, or scanning using barcode? need make payment after item being entered (typical retailer system), or need make payment after asked bill (typical restaurant system). later decide architecture.

now asking question:

in addition windows application pos, main idea make native (not html5) mobile application in tracking orders

as have have said before, architecture depend on device used , how process done.

the mobile app should -

1. waiters take , track order.
2. the manager should able check employees's leaves,timings,etc.

first point requirement 2nd point. what? track employee's leaves, timings,etc? should included in hr module, not pos module. keep application scope smallest , make sure each of module in same topic.

on pos part - thinking make particular restaurant work local database synced central database.

try , know whether distributed database design or not. search articles pros , cons design , make sure know sequences before starting design.

are on right track? can html5 in mobile application?

it same question as: can keyboard type? html5 language used in web - server programming. kind alike of rendering / layout technique. if want aim modern browser such latest version of firefox, go it. really, know how html5 can you, or know downside of using html5?
