A user model is the collection and categorization of personal data associated with a specific user. A user model is a (data) structure that is used to capture certain characteristics about an individual user, and a user profile is the actual representation in a given user model. The process of obtaining the user profile is called user modeling. [3]
A view container and a view component can be associated with events, that can represent users' interactions or system-generated occurrences. For example, an event for selecting one or more items from a list or for submitting inputs from a form. The effect of an event is represented by an interaction flow connection. The interaction flow ...
Facilitate testing and user documentation. With content based upon an action or event flow structure, a model of well-written use cases also serves as excellent groundwork and valuable guidelines for the design of test cases and user manuals of the system or product, which is an effort-worthy investment up-front.
Activity diagrams [1] are graphical representations of workflows of stepwise activities and actions [2] with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities.
UMLi is an extension of UML, and adds support for representation commonly occurring in user interfaces.. Because application models in UML describe few aspects of user interfaces, and because the model-based user interface development environments (MB-UIDE) lack ability for modeling applications, the University of Manchester started the research project UMLi in 1998.
Data flow diagram with data storage, data flows, function and interface. A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system). The DFD also provides information about the outputs and inputs of each entity and the process itself.

Sterneckert (2003) suggested that flowcharts can be modeled from the perspective of different user groups (such as managers, system analysts and clerks), and that there are four general types: [10] Document flowcharts, showing controls over a document-flow through a system; Data flowcharts, showing controls over a data-flow in a system
