The repository contains the SQL scripts for creating a Data Vault model for a PostgreSQL demo database available at https://postgrespro.com/community/demodb. The er-diagrams and some SQL script contained here are accompanying material for the article
Practical Introduction to Data Vault Modeling
published on medium.
There are two versions of the modeling discussed in the article. The directory dv-version1 contains the code of the first version, while dv-version2 contains the code of the second version. The directory ER-Diagram contains all er-diagrams created by the author except for the diagram bookings-schema, which was adapted from https://postgrespro.com/docs/postgrespro/10/apjs02.html The zip file bookings-demo-small-en contains the script for creating the small version of the demo database.
-
Download and unzip data-vault-modelling-mainzip
-
CD into directory with that file.
-
Unzip the file bookings-demo-small-en
-
Install the small version of the demo database
- psql -f bookings-demo-small-en/demo-small-en-20170815.sql -U postgres
Note that a new database named demo will be created. If the database already exists,it will be dropped and recreated.
-
Install Version 1
- psql -f dv-version1/create_version1_tables.sql -U postgres -d demo
- psql -f dv-version1/load_version1_tables.sql -U postgres -d demo
The tables of Version 1 will be created in a new schema named dv. If the schema dv already exists, it will be dropped and recreated.
-
Install Version 2
- psql -f dv-version2/create_version2_tables.sql -U postgres -d demo
- psql -f dv-version2/load_version2_tables.sql -U postgres -d demo
The tables of Version 2 will be created in a new schema named dv1. If the schema dv1 already exists, it will be dropped and recreated.
All scripts of Version 1 and Version 2 are tested on the small version of the demo database.
