P3_103 Schema and Imports (Python)

info

This course was written for the Weaviate Python client API (v3), and is now deprecated.

If you are new to Weaviate, we recommend you start with one of the 100-level courses written with the v4 client API, such as those for working with text data, your own vectors, or multimodal data.

Unit overview​


The previous units introduced you to the fundamentals of Weaviate, its capabilities, and how to execute basic queries on existing data. Now that you're familiar with the various query types, it's time to explore how to populate your own Weaviate instance with data.

In this unit, we'll examine how to use Weaviate to effectively structure your data so that you can retrieve the right information the way you want. We'll delve into defining a schema for your data and importing data into Weaviate.

By the end of this unit, Weaviate's overall data architecture will start to become clearer in your mind. This will start to empower you to build a vector database that really suits your needs and goals.

Let's get started.
