In $$Cinema $$World $$system$,$the $$customer $$will $$be $$able $$to $$create $$an $$account$,$query $$about $$movies$,$book $$a $$movie $$and $$do $$a $$payment $$that $$will $$be $$validated $$by $$third $$party $$banking $$systems$.$The $$admin $$will $$be $$able $$to $$add $$movie$,$delete $$a $$movie $$and $$edit $$a $$movie$.$

Each $$movie $$is $$described $$with $$ID$,$ movie $$duration$,$price $$and $$trailer$.$Where $$each $$movie $$can $$be $$either $$a $$family $$movie$,$action $$movie $$or $$documentary$.$The $$client $$can $$do $$booking $$for $$at $$least $$one $$movie$.$Each $$booking $$is $$described $$with $$booking $$ID$,$ number $$of $$booked $$seats$,$movie $$ID$,$ and $$total $$price$.$ For $$each $$movie $$there $$is $$a $$timing $$that $$is $$uniquely $$identified $$by $$date $$and $$time $$slot$,$so $$no $$two $$same $$movies $$can $$run $$at $$the $$same $$time$.$Also$,$movie $$timing $$includes $$time $$slot $$from $$and $$time $$slot $$to$.$

$$In $$the $$cinema$,$a $$movie $$is $$run $$in $$any $$of $$the $$halls $$that $$each $$is $$identified $$by $$hall $$no$.$ Every $$hall $$must $$include $$a $$screen $$that $$can $$be $$regular $$or $3$D$.$

Admin $$has $$the $$charge $$of $$adding $$a $$movie $$by $$selecting $$add $$movie $$from $$the $$menu$.$Then $$system $$will $$show $$adding $$movie $$screen$.$Admin $$shall $$enter $$movie $$details $$such $$as $$name $$and $$date$.$The $$system $$checks $$whether $$the $$movie $$is $$valid$.$If $$yes$,$the $$system $$will $$request $$the $$admin $$to $$upload $$the $$movie$,$and $$the $$admin $$responds $$by $$uploading $$the $$movie$.$Then $$system $$send $$successful $$movie $$upload$.$If $$not$,$the $$system $$displays $$error $$message $$and $$clears $$all $$fields $$in $$the $$adding $$movie $$form$.$

Regarding $$booking $$a $$movie$,$the $$customer $$selects $$a $$movie$,$then $$system $$shows $$movie $$details $$and $$trailer$.$The $$customer $$shall $$fill $$watching $$movie $$date$,$and $$the $$system $$shall $$respond $$by $$shopping $$all $$available $$free $$dates$.$The $$customer $$must $$select $$a $$time $$slot$.$The $$system $$shows $$the $$selected $$slot$.$Then $$customer $$must $$enter $$number $$of $$people $$who $$will $$be $$watching$.$The $$system $$then $$checks $$all $$entered $$information $$validity$.$If $$valid$,$then $$system $$forwards $$customer $$to $$payment $$window $$and he does $$the $$payment $$and $$thank $$you $$message $$is $$sent $$to $$him by $$the $$system$.$If $$not $$valid$,$the $$system $$shows $$error $$message$.$
