    6. Data Warehouse Design: Creating the Front End
  • In a traditional architecture there are three common data warehouse models: virtual warehouse, data mart, and enterprise data warehouse: A virtual data warehouse is a set of separate databases, which can be queried together, so a user can effectively access all the data as if it was stored in one data warehouse.
A data warehouse diagram helps organizations make decisions when upgrades are needed or changes to infrastructure are necessary for expansions. They can also be used when planning the design of a new warehouse.

What Is A Data Vault?

A Data Vaultis a more recent data modeling design pattern used to build data warehouses for enterprise-scale analytics compared to Kimball and Inmon

What Is Dimensional Modeling?

Dimensional modeling is a bottom-up approach to designing data warehouses in order to optimize them for analytics

Data Organization Principles in Each Layer of The Lakehouse

A modern lakehouse is an all-encompassing enterprise-level data platform

Bronze Layer — The Landing Zone

The Bronze layer is where we land all the data from source systems

Silver Layer — The Enterprise Central Repository

In the Silver layer of the Lakehouse, the data from the Bronze layer is matched, merged

Gold Layer — The Presentation Layer

In the Gold layer, multiple data marts or warehouses can be built as per dimensional modeling/Kimball methodology. As discussed earlier

The Lakehouse Data Organization Paradigm

To summarize, data is curated as it moves through the different layers of a Lakehouse. 1. The Bronze layeruses the data models of source systems

What is the difference between a transactional and a warehouse data model?

The main difference between a transactional and a warehouse data model is in the purpose of one and the other

Transactional models are designed to optimize the management of transactions in business applications

Their primary objective is to maintain the consistency and integrity of the information stored in the database

Which data models are relevant to a data warehouse?

Below are a few data models that may be relevant to a data warehouse: ER-model: The entity-relationship (ER) model represents the data elements as entities and their relationships

It is suitable for transactional data warehouses

Dimensional model: This model represents the data elements as dimensions and measures
