MyWind

MySQL version of 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.

Files

• Model:
  • northwind.mwb (MySQL Workbench v6.2)
• EER Diagram:
  • northwind-erd.pdf
  • northwind-erd.png
• Structure:
  • northwind.sql
  • northwind-default-current-timestamp.sql (uses DEFAULT CURRENT TIMESTAMP, requires MySQL 5.6.5+)
• Data:
  • northwind-data.sql

Creating MyWind

• Created Northwind.aacdb using MS Access 2010 (File > New > Sample Templates > Northwind > SaveAs)
• Converted Northwind.accdb to (MySQL) SQL using BullZip "Access to MySQL".[1]
• Manually edited SQL
  • Converted CamelCase identifiers to lower_case_with_underscore
  • Replaced space and slash characters in identifiers_with_underscores
  • Renamed primary key columns "id"
  • Renamed foreign key columns "xxx_id" (e.g. "inventory_id")
  • Changed record create and modified date columns to type DATETIME to avoid TIMESTAMP range (1997 - 2038 UTC) and other limitations
  • Created separate structure and data SQL files (or maybe it was done with Access to MySQL).
• Imported SQL into MySQL Workbench
  • Added foreign key relationships visually
  • Exported EER Diagrams
