 # AdventureWorks for Postgres
 
-This project provides the scripts necessary to set up the OLTP part of the go-to database used in
-training classes and for sample apps on the Microsoft stack. The result is 68 tables containing HR,
-sales, product, and purchasing data organized across 5 schemas. It represents a fictitious bicycle
-parts wholesaler with a hierarchy of nearly 300 employees, 500 products, 20000 customers, and 31000
-sales each having an average of 4 line items. So it's big enough to be interesting, but not
-unwieldy. In addition to being a well-rounded OLTP sample, it is also a good choice to demonstrate
-ETL into a data warehouse.
+This is based off the work done by [lorint](https://github.com/lorint/AdventureWorks-for-Postgres). We've already done the work to convert the csv's to be compatible with postgres. If you would like the original files, head over to [Adventure Works 2014 OLTP](https://msftdbprodsamples.codeplex.com/downloads/get/880662) download page. The download includes a script for loading the data into MSSQL Server.
 
-Provided is a ruby file to convert CSVs available on CodePlex into a format usable by Postgres, as
-well as a Postgres script to create the tables, load the data, convert the hierarchyid columns, add
-primary and foreign keys, and create some of the views used by Adventureworks.
+## Getting started
 
-## How to set up the database:
+First, make sure you have postgres installed. You can do this by typing `psql` in terminal.  
+If nothing comes up, install postgres using `brew install postgres`. This will install and initialize a postgres database.
 
-Download [Adventure Works 2014 OLTP Script](https://msftdbprodsamples.codeplex.com/downloads/get/880662).
-(If this link becomes broken then here's the [original page](https://msftdbprodsamples.codeplex.com/releases/view/125550).)
+### Windows
 
-Extract the .zip and copy all of the CSV files into the same folder, also containing update_csvs.rb file and install.sql.
+Head over to [https://www.postgresql.org/download/windows/](https://www.postgresql.org/download/windows/) and follow the instructions.
 
-Modify the CSVs to work with Postgres by running:
-```
-ruby update_csvs.rb
-```
-Create the database and tables, import the data, and set up the views and keys with:
-```
-psql -c "CREATE DATABASE \"Adventureworks\";"
-psql -d Adventureworks < install.sql
-```
-All 68 tables are properly set up, and 11 of the 20 views are established.  The ones not built are those that rely on XML functions like value and ref.  To see a list of tables, open psql, and then connect to the database and show all the tables with these two commands:
-```
-\c "Adventureworks"
-\dt (humanresources|person|production|purchasing|sales).*
-```
+### Run the script
 
-## Motivation
+Once you have confirmed your postgres install, run the following two lines:
 
-Five years ago I was pretty happy developing .NET apps for large organizations.  The stack was
-mature, and good practices surrounding software development were very respected.  The same kind of
-approach I appreciated from my days writing Java code was there, and the community was passionate.
+	psql -c "CREATE DATABASE \"Adventureworks\";"
+	psql -d Adventureworks < install.sql
 
-Then along came Windows 8.  The //build/ conference in September 2011 revealed its first beta, and
-even with that early peek at the new direction things were headed, it was clear that everything about
-the platform was a haphazard combination of the new Metro apps along with all the traditional control
-panel and options and API for classic code.  It left a very bad taste in my mouth.  Perhaps it would
-look pretty, but be very unusable.  I couldn't see it ever being successful.  Once the "red pill"
-registry setting vanished from the builds in mid-2012, the Windows 7 interface was then no longer
-available even in Server editions.  I knew it was time for a change.  For a year I stuck it out
-watching to see if there was any hope for some kind of tablet miracle out of Redmond, but I was
-consistently unimpressed.
-
-In mid-2013 a friend looped me in on a new project involving Ruby on Rails, and I fervently dove in
-and have very much enjoyed the elegance of that ecosystem.  A big part of that has been ramping up my
-knowledge of Postgres.  What a great database engine!  I figure that others departing the Microsoft
-camp may appreciate the same data samples they're familiar with, so I created this along with the
-Northwind sample.  It's been useful in the classroom training folks about Rails.  I expect with the
-heavy-handed tactics Microsoft has now used around Windows 10 that even more organizations will
-choose to transition away from that platform, so there will be lots of opportunity for samples like
-this to help people learn a new environment.
-
-As well, with the imminent release of SQL Server 2017 for Linux, this sample could be used to
-evaluate performance differences between Postgres and SQL 2017.  Never thought I'd see the day that
-MS SQL got compiled for Linux, but alas, here we are. 
-
-Let's keep coding fun.
-
-Enjoy!
+You're all set!
