Goal: To gather ripcurrent data to assist in
research
 Collect detailed information
◦ Wave data
 Water level
 Wave period
◦
◦
◦
◦

Time & Location
Frequency
Type of rip current
Pre-existing weather conditions
Compare to other tidal/buoy data


Use data to better
understand causes
of rip currents
Improve public
safety
◦ Avoid potential
dangers on the beach

Mobile application used by lifeguards
◦ Submit reports and input data as it happens

Website used by researchers
◦ View data in real-time


Store all reports in central website/database
Researchers can collect and use all current
and historical data for analysis

Each group has different permissions and
features available.
Three main groups:
Lifeguards
Researchers

 Permission Enforcement
◦ Access Control Lists
Administrators



Use mobile
application
Submit rip current
reports
View reports
submitted within
last 24 hours




Use website
View rip current
reports
Search through all
reports
Collect large
quantities of data
from reports in a
batch

◦ Last 24 hours
◦ Full search

Features of the software that must be
included:
◦ Receive GPS location data from mobile device
◦ Transmit data to remote server
◦ Store data in database
◦ Display stored data
◦ Maintain a log of database modifications

Features of the software that must be
included:
◦ Multi-user account and login system
◦ User administration
◦ Security: Restrict access to system interfaces and
data
 Username and password
 User account permission hierarchy
 User permission enforcement
 Log user activities
If time permits…
 Pull external data
 Use with the data collected by the users of
this system
 Types of data:
◦ Coastal buoy data
◦ NOAA ocean data
◦ Expanded: NBDC buoys
Additional goals successfully implemented


Internet-connected smartphone or mobile
device
Mobile web browser:
HTML5 Compatible
◦
◦
◦
◦
Android
iOS
Blackberry
WebOS



Live web server
Provides functionality for both website and
mobile application
Specifications:
◦
◦
◦
◦
Apache2
PHP 5
MySQL
CakePHP 2.0 Framework

Web browser for non-mobile application use
◦ Internet Explorer 7+
◦ Firefox 3.0+
◦ Google Chrome

Interface with existing database systems
◦ Retrieve data from 3 local buoys and Atlantic City
tide gauge
 Access given by Stevens researchers
◦ Expanded to buoys from NBDC
What’s needed:
 Large project
◦ Many files and code


Collaboration
Simultaneous editing
Solution: Version Control System
◦ Subversion

User workstation
◦ Connects to web server and interacts from browser
◦ System administration and data collection

Mobile Device
◦ Internet-enabled device connects to web server
◦ Remote access and submission to system

Web Server
◦ Provides system interface and functionality
◦ Communication with database server

Database Server
◦ Store all system data and retrieve when necessary

Models
◦ Contains all data access functions
◦ Ensures data is in a usable format for DBMS

Controllers
◦ Functions to access data and determine which web
page to display
◦ Data accessed through models, returned to views

Views
◦ Contains all web pages
◦ Has all logic for organizing and displaying data to
user (through UI)

Mobile Views
◦ Similar to full website
◦ Optimized CSS/Javascript for mobile devices
 Lighter UI
 Smaller size
◦ Redirect based on user agent

Database Management System (DBMS)
◦ MySQL backend
