Design – Database

Miscelenious

• We Use• JavaScript to

– To interact with Google Maps – To interact with customer in client side with HTML help (UIL)

• PHP – To implement our business layer (BOL)– To fetch data from database (DAL)

• Google Maps API allows us • To create a map inside an html container• To create custom markers on the map that we can use to display our

custom advices• To draw an area on the map to warn the user of problematic areas• To create a route between two points• To create custom route directions regarding the time consumption of

each step
