Then Heroku creates a random sub domain for our application. We can change it as we like. Then deploy the app to Heroku by

Now we can visit our application by using the address.

Heroku provides different plans to deploy the application and for using the database space. Here the plan is Blossom. It is free and can take 5MB database maximum.

Git is a version control system and a very good friend of a developer. Todays all projects are very much depend on git. What’s the use of git? If a programmer develops a project he want to take copies of the progressing project at stage by stage. Using git we can ‘commit’ the project by giving comments like ‘first commit’ , ‘second commit’ etc. When a programmer deletes a file, he can recover the file using git. Git uses a tree structure to hold the data. It has a parent repository called master branch. We can change the branch to another and can process the data. Multiple branches are using when working on a projects with multiple developers. This branch master is unaltered when working on another branch. Download .rpm packages from RPM packages, and .deb packages from Debian Packages
