The key may be part of the data (as with primary keys in relational databases) however, it can also be used on its own.

You can have your car running in no time with some knowledge and perseverance. Tools for programming Software that aids developers to write code, test and debug is called a programming tool.

The tools for programming are diverse and vast with a wide range of tools available. Examples include: Integrated Development Environments (IDEs), compilers, version control systems and debuggers.
