Data Modeling for the Virtual Coach By Eddy

The Virtual Coach is a web-centric virtual environment that creates temporally dynamic clinical exercises known as situational simulations, with the intention of exposing participants to rapidly unfolding events and the pressure of decision-making. This paper deals with the databases, which store all the data relevant to situational simulations executed by the Virtual Coach. It defines the nature of the data and describes the relational databases used. The Virtual Coach uses two types of databases, the ‘asplanned’ and the ‘as-built.’ While the ‘as-planned’ database stores information about how a particular project can be completed when executed on schedule and within budget, the ‘as-built’ database, dynamically records data regarding the actual execution of the project, by a particular participant. This paper discusses the design and the modes of functioning of these databases.
