How to Generate a Snowflake Database Model DDL

In this article, we will see how to use Vertabelo to create a Snowflake DDL script. We’ll start from a data model created online and walk you through the process of generating the SQL script that will create the physical database. Vertabelo is a powerful yet easy-to-use data modeling tool that can help you create database models for many database engines, including Snowflake. What Is Snowflake? Snowflake is a Cloud-based Database-as-a-Service designed by former Oracle engineers.

How to Model Snowflake External Tables in Vertabelo

There is a lot more data than stored in databases. This raises the question of how to access all the external data from the database. The external tables come to the rescue!

Star Schema vs. Snowflake Schema

In the previous two articles, we considered the two most common data warehouse models: the star schema and the snowflake schema. Today, we’ll examine the differences between these two schemas and we’ll explain when it’s better to use one or the other. The star schema and the snowflake schema are ways to organize data marts or entire data warehouses using relational databases. Both of them use dimension tables to describe data aggregated in a fact table.

The Snowflake Schema

In a previous article we discussed the star schema model. The snowflake schema is next to the star schema in terms of its importance in data warehouse modeling. It was developed out of the star schema, and it offers some advantages over its predecessor. But these advantages come at a cost. In this article, we’ll discuss when and how to use the snowflake schema. The Snowflake Schema if (typeof VertabeloEmbededObject === 'undefined') {var VertabeloEmbededObject = "
