Archival data has a new mission: Critical; it's not what it used to be. On regular basis, Archive Systems would scan anywhere from 175,000 to 275,000 single pages per day for a customer's digital archives and for online retrieval using up to ten lower speed and smaller capacity scanners.
Theories are formulated to explain, predict, and understand phenomena and, in many cases, to challenge and extend existing knowledge within the limits of critical bounding assumptions. The theoretical framework is the structure that can hold or support a theory of a research study.
The graphical model framework provides a way to view all of these systems as instances of a common underlying formalism. This view has many advantages -- in particular, specialized techniques that have been developed in one field can be transferred between research communities and exploited more widely.
