What does the database symbol mean in Eclipse icons?

Question

What does the database symbol mean in Eclipse icons?

I marked the database symbol in two places here:

Answer 1

Files with the yellow cylinder overlay are stored in your source control system, while files without have not been added. How you add files is dependent on what system you use.

Answer 2

ChangeObject.java is not yet added to your repository, thats why it does not have the cylinder icon attached.

You can right click on the containing project or package to synchronise and update your repository with the new files.

Answer 3

it depicts the project is version controlled. And the file has not been modified locally since your last check out. & the number is the version number. The file without the number is newly added, i.e. not version controlled.

to check in to TFS:

1. right click on the project (not just a file)

2. select team

3. select check in pending changes

4. now you'll get a window showing files with changes (including new files), you can select whatever you want to check in.
