2. 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

3.  Use data to better understand causes of rip currents  Improve public safety ◦ Avoid potential dangers on the beach

4.  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

5.  Each group has different permissions and features available.  Three main groups: Lifeguards Researchers Administrators  Permission Enforcement ◦ Access Control Lists

6.  Use mobile application  Submit rip current reports  View reports submitted within last 24 hours

7.  Use website  View rip current reports  Search through all reports  Collect large quantities of data from reports in a batch

8. Lifeguard AdminResearch Admin  Add, view, and edit managed lifeguards within local community  Disable users or alter privileges  View local rip current reports  Add, view, and edit researchers and lifeguard administrators  Disable users or alter privileges  View all rip current reports ◦ Last 24 hours ◦ Full search

9.  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

10.  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

11. 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

12.  Internet-connected smartphone or mobile device  Mobile web browser: HTML5 Compatible ◦ Android ◦ iOS ◦ Blackberry ◦ WebOS

13.  Live web server  Provides functionality for both website and mobile application  Specifications: ◦ Apache2 ◦ PHP 5 ◦ MySQL ◦ CakePHP 2.0 Framework

14.  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

15. What’s needed:  Large project ◦ Many files and code  Collaboration  Simultaneous editing Solution: Version Control System ◦ Subversion

16.  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

17.  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)

18.  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

19.  Username  Password hash  Password salts  Email  Community  User type (sets permissions)

23.  Date/time of occurrence  Reporting user  GPS/Location coordinates  Intensity  Nearby structure information  Description (comments, other info)  Buoy data (external source) ◦ Wave height, frequency ◦ Station ◦ Date/time of tidal data reading
