-## Headstorm Interview
+# HeadStorm_Challenge
+Repository that holds work for the HeadStorm Challenge 
 
-Welcome to the Headstorm interview challenge!  This repository is designed for candidates to [fork and create Pull Requests](https://help.github.com/en/articles/creating-a-pull-request-from-a-fork) with their solutions.  There are two types of 'take-home' problems here:
+## backEnd_challenge.py
+This is the file that holds the code for the back end challenge. It is a standalone file with on dependencies on any other file.
 
-### Challenges
-These are domain specific problems that can be submitted individually.  You can choose from backend, frontend, databases, or data-science.  You can submit a PR for one, many, or all the challenges.
+## database_challenge.py
+This is the file that holds the code for the database challenge. Using postgreSQL, python commands were used to create the database, the tables, and the INSERT commands to insert the data into the tables. Some dependencies include the testingFile.py, which randomly generated 25 entries that would be used to insert into the tables in the database and the oldData.txt, which held this information. The database_relationalModel.jpg shows the ER model of how this database is constructed. 
 
-### Interviews
-These are language specific interview questions and you can choose the language in which you implement your solution.
+## frontEnd_Challenge.html
+This is the file that holds the code for the front end challenge. One of the dependencies is the browserIcon.png file that is used for the icon on the browser, but aside from that this html file is a standalone file.
