Collaborative Applications

This document provides a comprehensive overview of collaborative applications, focusing on their definition, forms of communication, and user interactions. Collaborative software facilitates real-time and asynchronous communication between users, employing various mechanisms such as implicit and explicit messaging, session-based, and artifact-based communication. Key examples include traditional methods like file sharing, email, and chat systems, as well as novel applications utilizing virtual and augmented reality. The document also discusses structured messaging and automated notifications in collaborative environments.
