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 Administrators Permission Enforcement ◦ Access Control Lists
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

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
