MyWind

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

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

The Northwind sample database provided with Microsoft Access is a tutorial schema for managing small business customers, orders, inventory, purchasing, suppliers, shipping, and employees. My problem was I wanted to experiment with the Northwind schema using MySQL.

WARNING

• northwind.mdb -> northwind-02.mdb (and other new/modifed files in this commit) may be the result of correcting or improving the ERD model where it relates to sales orders and shipping (as presumed by addition of northwind-02-sales-orders-and-shipping.png). Whoever walks this way, please figure this out and deal with it appropriately.

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
