Was talking with a friend tonight who had looked at the MySQL and Postgres licenses (I have not), and he noted that Postgres was absolutely free, while MySQL was only free for internally developed apps, in a commercial installation.<br>

What is the issue, and is it an issue in practice?<br></blockquote></div><br>PostgreSQL is BSD licensed. Therefore, companies can take it, modify it, and close it off as much as they like under proprietary licenses. Much like what Apple did to NetBSD for example, and more practically, what a company like EnterpriseDB is (a PostgreSQL proprietary derivative).<br>
<br clear="all">MySQL is dual licensed. The community version is GPL, and hence it is not any different from the Linux kernel, Drupal or other GPL software.<br><br>The proprietary license is how MySQL made their money: they told people who want to embed MySQL in commercial applications and then sell them to get a license that would not make their application GPL because of linking to it. <br>
<br>There are some subtle details and a bit of controversy that I will cover in the May meeting about MySQL. <br><br>But, the bottom line is: if you want to just use MySQL then there are no issues, it is as free as they come. If you want to incorporate it in a closed source product that will sell/distribute, then you should investigate deeper.<br>
