Data Layer

!This!is!the!lowest!layer!in!client!application!which!is!responsible!for!dealing!with!the!upload!and!download!of!data.!In!this!application!,we!are!primarily!dealing!with!three!types!of!data!flow!within!the!application.!Most!of!the!data!is!the!crowdsourced!data,!which!is!downloaded!by!the!user!and!saved! under! ‘My!Saved!Routes’! to! have! the! information! ready! on! his! device! (stored! locally).!Also,! there! is! data! flow! from! the! user’s! device! to! the! backend!when! he/she! uploads! custom!routes! and! participate! in! crowdsourcing.! Finally! there! is! external! data! from! third! party!applications!like!Google!Maps!and!imaging!services!like!Flickr!is!downloaded!by!the!app!using!external!APIs.!!!!!!!

Local DataStore

!To!facilitate!offline!mode!of!operation,!client!device!maintains!a! local!database!where! it!stores!all!the!pertinent!information!from!the!backend!crowdsourced!data!for!the!routes!saved!under!the!user’s! ‘My!Saved!Routes’.!Also!a!backup!is!maintained!at! the!user’s!personal!cloud!space!(or!user’s!preference!like!google!drive,!dropbox!etc)!for!quick!access.!Also!the!latest/current!route!is!also!saved!in!fast!access!cache!memory!when!the!user!starts!to!trek.!!!

Support Infrastructure/ Services (BackEnd)

!All! the! crowdsourced! data! is! uploaded! to! an! external! high+capacity! and! highly! available!proprietary!database,!where!all!data!is!collected,!organized!,!analyzed!and!processed!for!quick!access! and!ensures! that! user! always! gets! the! accurate! information.!Various! complex! access!and! data! analytics! techniques! are! needed! to! be! used! for! this! purpose.!
