Combine Multiple Content Types and View I have need to create a page with following information.
Personal Information,
Address and 
Contract Information.

One Personal Information will have multiple address and multiple Contract information. I am thinking of creating three content types. The personal information page will have add address and add contract buttons which will popup the respective content type. When the address or contract popup is closed then control is passed to the Personal Information page, here I should be able to view the contact and address information just added in tabular format. I thought it may be a view.

My question is, Is it possible to achieve this kind of work in Drupal 7? If yes how can I do it. It will be nice to have some information so that I can look into the right direction. Some example sites would be help full.

Thanks
Instead of creating new content types. You can create fields and use FieldCollection module to group as many field as you like.

and show (Display) it using FieldCollection Views module.
