Groupware systems come defined under two natures. These natures are as follows:

• Synchronous groupware: includes the class of application that assist a group of physically separated people to interact with one another using real time systems or objects that are shared over the network. Synchronous groupware requires real-time coordination with their clients to find out the exact nature of the communication they are having.

• Asynchronous groupware: includes the use of electronic mails, structured messages, agents, etc. in the system for the communication. It also requires a specified workflow, and computer conferencing, techniques to set a communication between two different parties. The collaborations are only be performed and maintained if there is no restriction on the transfer of the data.
