MyWind

MyWind is a MySQL version of the Microsoft Access 2010 Northwind sample database.

The Northwind sample database provided with Microsoft Access is an excellent tutorial schema for a small business to manage customers, orders, inventory, purchasing, suppliers, shipping, and employees, using single-entry accounting. However, I wanted to experiment with the Northwind schema using MySQL.

WARNING

• northwind-02 (northwind-02.mwb and northwind-02-sales-orders-and-shipping.png) are a work in process and presumably related to improving the ERD model where it relates to sales orders and shipping, but the specifics have now been lost in time. If anyone sorts this out, I would sincerely appreciate a pull request (creating an issue would be just as appreciated). Thanks.

  • northwind.sql
  • northwind-default-current-timestamp.sql (uses DEFAULT CURRENT TIMESTAMP, requires MySQL 5.6.5+)

Creating MyWind

• Created Northwind.aacdb using MS Access 2010 (File > New > Sample Templates > Northwind > SaveAs).
• Created basic SQL equivalent of Northwind schema for MySQL using using BullZip "Access to MySQL".[1]
• Replaced CamelCase identifier names with lower_case_with_underscore identifier names.
• Replaced " " (space) and "/" (forward slash) characters in identifiers with underscores.
• Renamed table primary keys "id".
• Renamed table foreign keys "xxx_id" (e.g. "inventory_id").
• Changed record-create and modify-date columns to type DATETIME (to avoid the 1997 - 2038 UTC date range restriction of TIMESTAMP, and also other limitations).
• Added foreign key relationships and created ERD using MySQL Workbench.
• Imported SQL into MySQL Workbench
  • Added foreign key relationships visually
  • Exported EER Diagrams
