 # Data-Vault-Example-Northwind
 
-An example Data Vault data warehouse modelling Microsoft's Northwind sample database, built for SQL Server.
+An example Data Vault 2.0 data warehouse modelling Microsoft's Northwind sample database.
 
 
 ### Purpose
 
-The objective of this project is to develop an easily accessible example data warehouse illustrating how to model the well-known Northwind sample database using the Data Vault methodology.
-
-I intend the repository to mostly be of use to new Data Vault practitioners, providing a convenient option for hands-on experimentation. Hopefully it helps join a few dots on the somewhat steep learning curve that comes with Data Vault modelling.
+The objective of this project is to develop an easily accessible example data warehouse illustrating how to model the well-known Northwind sample database using the Data Vault 2.0 modelling standards.
 
 
 ### Setup
 
-1. Set up a SQL Server instance to hold the five component databases.
-2. Run the following SQL scripts in this order to create the five databases.
-	* SQL\DDL\Northwind\instnwnd.sql
-	* SQL\DDL\Create_Database_Stage_Area.sql
-	* SQL\DDL\Create_Database_Meta_Metrics_Error_Mart.sql
-	* SQL\DDL\Create_Database_Data_Vault.sql
-	* SQL\DDL\Create_Database_Information_Mart.sql
-3. Confirm setup is correct with an initial load. Run the following SQL script to execute the stored procedures for the Stage_Area and Data_Vault databases.
-	* SQL\ETL\Load_Data_Vault.sql
-4. Additionally, check the contents of Meta_Metrics_Error_Mart.error.Error_Log for any unexpected errors.

-### Documentation
-Basic documentation covering the data models and table mapping can be found in the Documentation directory.
+1. Set up a new SQL Server instance to hold the five component databases
+2. Run the following script to create the source Northwind database
+	* SQL\DDL\Source\instnwnd.sql
+3. Create the Data Vault databases. You have two options:
+   They can be set up quickly by executing the SQL scripts in the following directory
+	* SQL\DDL\Simple\...
+   Alternatively, they can be created in a step-by-step fashion by executing the scripts within
+	* SQL\DDL\Detailed\...
+4. Conduct the one-off load of ghost records into the necessary raw Data Vault tables
+	* SQL\DML\ghost records.sql
+5. Confirm setup is correct with an initial load. Run the following script to execute the stored procedures in Staging, Data_Vault, and Information_Mart
+	* SQL\DCL\load all.sql
+6. From here you should be able to query the dimensionally-modelled 'star' schema views in Information_Mart

+### Notes
+
+- Basic documentation covering the data models, standards, conventions, etc. can be located in the Documentation directory
+- This project does not cover the creation of the meta/metrics/error marts at this stage. Refer to Dan Linstedt's book 'Building a Scalable Data Warehouse with Data Vault 2.0' for the necessary details
+- Any attempt at building a production Data Vault 2.0 data warehouse should be preceded by taking the CDVP2 course offered by [Data Vault Alliance](https://datavaultalliance.com/) and their authorised training partners
+- This implementation is compliant with Data Vault 2.0 standards taught in CDVP2 as at July 2023
