In this article, we delve into Vector Databases by using Pinecone and explore the fundamentals of vector embeddings, indexes, and essential components of these databases. Furthermore, it will provide a guide on setting up a Vector Database on Pinecone, walking through the installation process, obtaining API keys, and initializing client connections.

The topics covered include Degenerate Dimension, Conformed Dimension, Role-Playing Dimension, Junk Dimension, Outrigger Dimension, and Slowly Changing Dimensions (SCD). The SCD category further delves into different types, such as Type 0 to Type 7, each with its unique approach to handling historical and changing data.

In this article, I will introduce the concept of the Basic Fact table in Dimensional data modeling. To understand this technique, we will explore the different types of data modeling and recap some fundamental knowledge, including the star and snowflake schemas, and the concepts of normalization.
