For the most part, integrated systems use the web or similar GUI interface designed for a network environment. Some of these softwares are offered by large commercial establishments with a background in network delivery such as cold fusion with its built in bulletin boards. These offer the educator an easy template in which to input data and support a certain type of course work. The above typologies provide a useful reference for the primary stages of setting up an educational environment but then there are still a number of products to choose from and a number of varied educational goals to consider. A further distinction might be made in terms of the dimensionality offered by the softwares.
Dimensionality refers to the longevity of the exchange or community being engendered.
Thus use of a web board, albeit logged, leaves little or no trace of the user. This holds true for the sophistication of the electronic classroom and video conferencing, as such they remain two dimensional - ie offer no illusion of time and continuity. An educational even occurs, is logged and stored but the next users to enter the system actively need to refer to the logs to see what has passed before rather that the events of the previous occasions affecting the boundaries and walls of the system. Each entry into an integrated system is clean the presentation remains unchanged. New messages may have been added to the bulettin board but the board itslef will retain the same format.
