Project Description

Imagine that Wave has just acquired a new company. Unfortunately, the company has never stored their data in a database, and instead uses a comma separated text file. We need to create a way for the new subsidiary to import their data into a database. Your task is to create a web interface that accepts file uploads, and then stores them in a relational database.

What your web-based application must do:

1. Your app must accept (via a form) a comma separated file with the following columns: date, category, employee name, employee address, expense description, pre-tax amount, tax name, and tax amount.
2. You can make the following assumptions
3. Columns will always be in that order
4. There will always be data in each column
5. There will always be a header line

An example input file named data_example.csv is included in this repo.

1. Your app must parse the given file, and store the information in a relational database.
2. After upload, your application should display a table of the total expenses amount per-month represented by the uploaded file.

Your application should be easy to set up, and should run on either Linux or Mac OS X. It should not require any non open-source software.

There are many ways that this application could be built; we ask that you build it in a way that showcases one of your strengths. If you you enjoy front-end development, do something interesting with the interface. If you like object-oriented design, feel free to dive deeper into the domain model of this problem. We're happy to tweak the requirements slightly if it helps you show off one of your strengths.

Once you're done, please submit a paragraph or two in your README about what you are particularly proud of in your implementation, and why.

Evaluation

Evaluation of your submission will be based on the following criteria.

1. Did your application fulfill the basic requirements?
2. Did you document the method for setting up and running your application?
3. Did you follow the instructions for submission?
