Basic SQL equivalent of Northwind schema

The Northwind database from Microsoft has a nice and simple schema that deals with with customers, orders, inventory, purchasing, suppliers, shipping, employees, and single-entry accounting.
This project is an attempt to create database agnostic srcript so that it can be reused in various other databases

Naming Convention used

  • Field names are in snake_case instead of CamelCase.
    • To facilitate some ORM frameworks (Hibernate/Spring Data) which uses field names to generate Java method names
    • Some databases and OS combination ignore case in field names therefore CamelCase dont make much sense
  • primary keys named id.
  • foreign keys constrained named as fk_table_name__reference_table_name.
  • All the column data types are valid with most databases

Two Datasets

  • Northwind Small (Few tables more data in each tables)
  • Northwind Extended (More Tables, More references, Less data per table)

Files

  • Northwind Small

    • schema.sql - DDL Statements (Table creation & Foreign Key definations)
    • data.sql - Insert statements to populate with sample data
  • Northwind Extended

    • schema_extended.sql - DDL Statements (Table creation & Foreign Key definations)
    • data_extended.sql - Insert statements to populate with sample data
  • NorthwindModel_MySQLWorkbench.mwb - This File can be opened with MySQLWorkbench, you may use it to generate schema script or model diagram
