PostgreSQL携手阿里云

    概要介绍 |   主要优点 |   核心功能表 |   版权声明

版权声明

PostgreSQL 使用PostgreSQL版权声明,它是类似BSD的版权。由于这个经 OSI认证的版权不限制PostgreSQL在商业环境和有 版权的应用程序中使用,因此被公认为是非常有灵活性和对商业应用是友好的。加上有多个公司的支持和源代码归属公共所有, 我们的版权使得PostgreSQL在那些希望在自己的产品里嵌入数据库的厂商中很流行,因为他们不用担心费用、嵌入软件的版权 锁以及版权条款的改变。

Why not the GNU General Public License?
People often ask why PostgreSQL is not released under the GNU General Public License. The simple answer is because we like our license and do not want to change it. If you are keen to read more about this topic, then please take a look in the Archives at any of the many threads on this subject, but please don't start yet another debate on the subject!
