Hi everyone. This tip is focused squarely at my DBA students, regardless of whether your platform if SQL Server, Oracle, MySQL, or Access.
Here’s the situation: you are designing a database and need to perform tests in your development environment using live data. Well, where in the world are you going to get that live data? You can’t very well invest half a workday typing fictitious records, right? Using a copy of your organization’s production data is a possibility, but this isn’t always feasible due to legal and/or ethical considerations.
Here’s how it works: Navigate to the Generator page, and select your output file format. You have a choice of HTML, native Microsoft Excel, XML, Comma-Separated Value (CSV), or native SQL.
Next, determine your target country for data fields such as addresses, and specify the number of results. Finally, fill in your column names and data types, being careful to mirror the schema of your development database tables. Click Generate to product the data set.

Isn’t that awesome! This Web site has saved my bacon quite a bit over the past several months, let me tell you. Some final points: the site owner offers the generatedata.com source code for free download, bound only by the GNU license. Also, site users who donate $20 or more to the site are given a user account at generatedata.com and are allowed to run much larger record batches than the non-paying public (the free online tool can generate only up to 200 records at a time).
I hope that you found this tip helpful. Happy studying!
