A data model uses a graphical user interface (GUI) for recording and organizing information regarding an object of care. The GUI enables a user to input an observation data set including a plurality of observations, the plurality of observations include at least a first subset of the plurality of observations and a second subset of the plurality of observations. The GUI enables the user to input an action data set including a plurality of actions, the plurality of actions includes at least a first subset of the plurality of actions and a second subset of the plurality of actions. The GUI enables the user to connect a first category of care to at least the first subset of the plurality of observations and at least the first subset of the plurality of actions, and to connect a second category of care to at least the second subset of the plurality of observations and at least the second subset of the plurality of actions, such that each connection indicates a relationship between the respective connected data.
