Swim Sheets

Overview

A common problem at swim meets is the backup that occurs from timers having to record the times for each swim on paper. The times then have to be manually entered in case one of the touchpads in the water does not register the swimmers touch, resulting in a false time. The objective of our project is to create an IPhone app to assist with swim meets. We want timers at swim meets to be able to input the time they recorded for the swimmer, based on the event number, lane number, and heat number, into the app instead of writing it on paper. This will allow the times recorded to go directly into the database instead of having to be manually entered at the conclusion of each swim event.

Here is a link to the weekly log that will contain updates on our progress for the project: https://classes.engineering.wustl.edu/ese205/core/index.php?title=Swim_Sheets_Log

Objectives

We want the IPhone app’s interface to prompt the user for the event number, heat number, and lane number. The app should then return the swimmer’s name based off the psych sheet for the overall meet. The user can then double check the accuracy of the name and override it if necessary. Once the swim is complete, a time will be entered and stored in an excel spreadsheet that could then be inputted into a swim database at a later time.

The main goals of this app are to:
1. Create a database that takes in the psych sheet and can report the swimmers name.

2. Prompt the user for event number, heat number, and lane number

3. Display data in an organized manner for overall meet results and analysis.

4. The database should take in an input of data, consisting of rosters, events, heat, and lane. These should be imported into the database from a .txt file that can be used by various teams to import into the database.

5. Results will be generated and be viewable from the database for the coaches use. These results can also be exported into a spreadsheet for viewing.

6. The data for each race will be received from inputs from the app, not an external source.

Challenges

ERD

An ERD is a way to model data that "graphically illustrates an information system's entities and the relationships between those entities". To generate this, we organized our data tables into separate entities on the graphs. We then put connections between the ID's that matched up in order to show how the different data tables interact with each other.

Design and Solutions

Design Components The Swimsheets app was designed to...

1. Allow coaches to fill out a simple Excel XML file
2. Have the file be uploaded, and the entries entered into a datatable automatically
3. Have an app read the datatable and display the swimmer for each specific event and heat to the corresponding lane on an app
4. Allow timers to input the time for each swim
5. Have the time data uploaded back into the datable
6. Display the results in an organized manner that can be found on the Swimsheets.com website

Interface

Server and Database

• We used Bluehost to set an SQL database and a web domain (swimsheets.com)
• Used myphpadmin to set up the data table that has columns consisting of: ID (an auto incremented number), Team, First Name, Last Name, Event Number, Event Name, Heat Number, Lane Number, Time (this value can be null)
• Data is inserted into this table when the coaches go online and download the excel XML file, fill it out, and upload it at swimsheets.com/upload.php based on the instructions listed on swimsheets.com
• Created various php files needed to execute our commands using sql queries:
  

upload.php: this is where coaches can submit the entries for the meet, once the submit button is hit, the page is directed to swimsheets.com/import.php

import.php: uploads the meet entry files into the datatable

getdata.php: establishes a connection with the SQL database, displays the entries datatable as an array that can be accessed using Xcode in swift

updateresult.php: takes in the time that is entered in the app and adds it to the entries datatable, if there is a blank time given for a Swimmer, "No Show" will be entered into the time field

displaybyevent.php: displays the entries table, sorted by event number and lane number

displaybyname.php: displays the entries table, sorted alphabetically by last name

displaybyteam.php: displays the entries table, sorted by team
