I'm doing a research at my Uni about Jira for my thesis

[Mohammad Ayman]

• What is Jira?
• How it works (technically)?
• Who is using it
  (size number of user, projects..., domains, what kind of problems they have, or feature requests)
• What kind of plug-ins are available
• How to write an plug-in for JIRA
• How data can be accessed and then how data can be manipulated? 

Thanks in advanced

@Mohammad Ayman, That's a whole lot of questions with a whole lot of answers.  I'll try to point you in the right direction:

• What is Jira?
  • https://www.atlassian.com/software/jira
• How it works (technically)?
  •  https://confluence.atlassian.com/jira/jira-documentation-1556.html
• Who is using it
  (size number of user, projects..., domains, what kind of problems they have, or feature requests)
  • This varies by company & team.  Can be from a small team of 1-2 people to organizations of 10,000+
• What kind of plug-ins are available
  • https://marketplace.atlassian.com
• How to write an plug-in for JIRA
  • https://developer.atlassian.com/server/framework/atlassian-sdk/create-a-helloworld-plugin-project/
• How data can be accessed and then how data can be manipulated?
  • JIra uses a variety of Databases so it would depend.
  • https://developer.atlassian.com/server/jira/platform/database-schema/

Your question are going to require a good amount of research on your part.  Hopefully, this will give you a start. GL.

@Peter DeWitt

First of all, thanks for your answers.

I almost checked all of those links and more before and I had some basic and quick answers for my questions.

But, since it will be a research topic, it should have more and deep information

[Peter DeWitt]

The answers you seek are available, you will need to spend some time reading through the online documentation and collating the information.  If there is something specific within one of those topics you don't understand, that would be the question/s to post.
