Except for the express version (desktop lite version) of Oracle database, Oracle database is not free for business and production. You need to buy official authorization, otherwise it is infringement.

2. Some people think it is free:

Up to now, Oracle database has not set up mandatory "activation" and "authentication" mechanisms on its system. Oracle database can be downloaded from official website or a third-party download point, or obtained by other means. Anyone can install and use it.

3. Related knowledge:

In the computer software industry, this kind of free installation is not uncommon, and it is mainly used for personal "learning practice". For example, in early windows98 and windows 2000, there was no other mandatory restriction mechanism except an installation serial number. As long as you know an installation serial number casually, you can install and use it "at will", but this does not mean that it is not infringing.

4. Others:

When there is no right to claim infringement, of course there is nothing. There are many torts in our life, but once someone claims rights and interests, and the interests of such torts are infringed enough, trouble will come. According to relevant laws and regulations, the claimant may require the infringer to pay enough price.
