Library of Over 500 Free Database Models
Databases are used in so many ways on so many websites. They are used for small tasks and large distributed networks scaled to handle millions of transactions per day. Sometimes we need a little help, a little push in the right direction in order to create a properly designed and normalized database. Thankfully, there are sites like DatabaseAnswers.org that provide help from “getting-started tutorials” to “database models.”
There are over 500 free database models at this website. They are all viewable in data model form and can be saved as an image or printed. You are also able to request an access database for any of the data models available by simply emailing and asking for one. The data models span many different categories from customers to bookstores to catalogs, and the list just goes on. I have listed the top 20 data models below.

The creator of all of these database models runs multiple database companies; one is in the UK; the other is in the US. He has also created data models that are included in Microsoft SQL Server 2005 Express. He offers his reason for providing these saying, “I design these Data Models for free to give something back to the Database community that has provided me with a good (and interesting) living for the past 15 years” (DatabaseAnswers.org). Be sure to check these out and show some love for all the hard work that went into creating these and offering them for FREE!
