A software license is a legal instrument (usually by way of contract law, with or without printed material) governing the use or redistribution of software. Under United States copyright law all software is copyright protected, except material in the public domain.his feature of proprietary software licenses means that certain rights regarding the software are reserved by the software publisher. Therefore, it is typical of EULAs to include terms which define the uses of the software, such as the number of installations allowed or the terms of distribution.
[edit] What is a license. A license is the right to use (RTU) the software and not the software itself. If you have a license, you can obtain a copy of the software media through whatever means-download, use the CDs from your last project, etc. Please note that Oracle doesn't use software keys.You can just install the software and use it. It is up to you and your consciences to license the software before using it.icenses are not tied to the product version. For example, an Enterprise Edition database license is equally valid for Oracle 9i, Oracle 10g, Oracle 11g or latest Oracle 12c. However, you are only entitled to new versions if you have a valid maintenance and support contract in place.
