### Feast project structure

The top-level namespace within Feast is a **project**. Users define one or more [feature views](feature-view.md) within a project. Each feature view contains one or more [features](feature-view.md#feature). These features typically relate to one or more [entities](entity.md). A feature view must always have a [data source](data-ingestion.md), which in turn is used during the generation of training [datasets](feature-retrieval.md#dataset) and when materializing feature values into the online store.

![](<../../.gitbook/assets/image (7).png>)

**Projects** provide complete isolation of feature stores at the infrastructure level. This is accomplished through resource namespacing, e.g., prefixing table names with the associated project. Each project should be considered a completely separate universe of entities and features. It is not possible to retrieve features from multiple projects in a single request. We recommend having a single feature store and a single project per environment (`dev`, `staging`, `prod`).

# Project

Projects provide complete isolation of feature stores at the infrastructure level. This is accomplished through resource namespacing, e.g., prefixing table names with the associated project. Each project should be considered a completely separate universe of entities and features. It is not possible to retrieve features from multiple projects in a single request. We recommend having a single feature store and a single project per environment (`dev`, `staging`, `prod`).

![](<../../.gitbook/assets/image (7).png>)

Users define one or more [feature views](feature-view.md) within a project. Each feature view contains one or more [features](feature-view.md#field). These features typically relate to one or more [entities](entity.md). A feature view must always have a [data source](data-ingestion.md), which in turn is used during the generation of training [datasets](feature-retrieval.md#dataset) and when materializing feature values into the online store.

The concept of project provide the following benefits:

**Logical Grouping**: Projects group related features together, making it easier to manage and track them.

**Feature Definitions**: Within a project, you can define features, including their metadata, types, and sources. This helps standardize how features are created and consumed.

**Isolation**: Projects provide a way to isolate different environments, such as development, testing, and production, ensuring that changes in one project do not affect others.

**Collaboration**: By organizing features within projects, teams can collaborate more effectively, with clear boundaries around the features they are responsible for.

**Access Control**: Projects can implement permissions, allowing different users or teams to access only the features relevant to their work.

## What is Feast?

Feast (Feature Store) is an open-source feature store designed to facilitate the management and serving of machine learning features in a way that supports both batch and real-time applications.

For more info refer to [Introduction to feast](../README.md)

## Prerequisites
* Ensure that you have Python (3.9 or above) installed.
* It is recommended to create and work in a virtual environment:
```sh
# create & activate a virtual environment
python -m venv venv/
source venv/bin/activate
```

## Overview

In this tutorial we will:

1. Deploy a local feature store with a **Parquet file offline store** and **Sqlite online store**.
2. Build a training dataset using our time series features from our **Parquet files**.

### Step 5: Generating training data or powering batch scoring models

To train a model, we need features and labels. Often, this label data is stored separately (e.g. you have one table storing user survey results and another set of tables with feature values). Feast can help generate the features that map to these labels.
