The process of learning Analytic can be challenging.
You have to find
- A real world dataset
- A database you can store the dataset into and query
- Interesting questions for which you can write SQL queries
Finding all three can be a big challenge.
The challenge is really in setting up your own environment. And this is where Docker comes into play.
Docker is a technology that has changed the IT landscape in the last decade. Docker is a tool that can setup any technology such as a database in your own system without you having to worry about installing hundreds of other things along the way.
And Docker is available for Windows, Mac and Linux. The video below will help you install Docker on your system.
Once you have Docker installed you will then be able to use "images" which come in all flavors. Need a database? There is an image for that. Need to play with Spark, get the image from Docker Hub (the hub of images).
And other people out there put together images and create even more avenues for you to try things out.
We have created an image which you can use to learn Analytics. This images has;
- A Postgres Database
- A pre-loaded dataset of almost 1 Million Play Store app attributes
- A client tool inside the image which you can use to run SQL queries and see the results
- And the most important of all, we have created a set of 30+ questions for you to practice.
INSTRUCTIONS TO GET STARTED
The first step is to pull the image from Docker as shown below.
docker pull harshsinghal/pgimage-tutor:latest
Once you have downloaded the image, you need to run the image by issuing the command below.
docker run -d --name 'pgimage-tutor' -p 8081:8081 -e POSTGRES_USER=root -e POSTGRES_PASSWORD=root -e POSTGRES_DB=data pgimage-tutor:latest
When this is done head over to your browser and type
You will see the interface below. Please use the values in the screenshot below and type them into the input prompts and click on Connect
Once you have clicked on Connect you will see pgweb interface.
Now you can write SQL queries into pgweb and see the results right below displayed in tabular format.
