Welcome to the world of Zillion! A robust data modeling and analytics tool that’s designed to simplify the complexities of data analysis. In this guide, we’ll unpack how to install and use Zillion, explore its features, and provide troubleshooting advice to ensure a smooth experience. Let’s dive in!

Installation

Warning: This project is currently in an alpha state and is subject to change. It’s important to test carefully for production use and report any issues.

shell$ pip install zillion
or
$ pip install zillion[nlp]

Primer

Before we jump into Zillion’s functionalities, let’s clarify some fundamental concepts that will be useful:

• Metrics: These represent the facts and measures that can be broken down.
• Dimensions: These are the attributes used for labeling and filtering.

Zillion simplifies SQL writing, allowing you to execute queries in a straightforward manner:

python
result = warehouse.execute(
    metrics=[revenue, leads],
    dimensions=[date],
    criteria=[
        (date, , '2020-01-01'),
        (partner, '=', 'Partner A')
    ]
)

Analogy

Think of Zillion as a master chef in a bustling restaurant kitchen. Instead of you needing to chop and prepare every ingredient (writing SQL), the chef (Zillion) takes care of all the heavy lifting while you focus on presenting the perfect dish (your data analysis).

Defining Metrics and Dimensions

In Zillion, fields can be categorized into:

• Dimension Tables: Reference tables containing related attributes.
• Metric Tables: Fact tables that carry metrics and related attributes.

Executing Reports

The purpose of Zillion is to execute reports against a warehouse efficiently. For example:

python
result = warehouse.execute(
    metrics=[revenue, leads],
    dimensions=[date],
    criteria=[
        (date, , '2020-01-01'),
        (partner, '=', 'Partner A')
    ]
)
print(result.df)  # Expects a Pandas DataFrame

Troubleshooting

If you encounter errors such as UnsupportedGrainException, this generally implies that the requested report is asking for data in a manner that conflicts with the relationships in your tables. To remedy this, ensure that the appropriate metrics and dimensions are linked and correctly defined.
