Explanation / Answer

The Differences Between Data Entry and Data Capture :

Data capture is when a company acquires new data from source documents which could be anything from records of business transactions to customer usage history. Comparatively, data entry is translating the collected data into a readable format that makes analyzing and storing data simpler.
Several key factors should be considered before knowing if data entry or data capture is right for you:
Type of information – Is the data more statistical or word-based?  
Volume of data – Is it a large consideration set or small amount of data?
Retrieval of documents – Will your documents be collected electronically or on paper?
Desired amount of indexing – Does your information require extensive indexing?
Structure of data – Is the data always formatted the same or does it have a different format every time?
Time – Do you have the extra time for data entry or is time limited?

Basic guidelines of effective user effective design :
1. Research Your Audience
2. Think Responsive
3. Identify User Interactions
4. Readability Is A Top Priority
5. Incorporate Familiar eLearning Navigation Controls
6. Consistency Provides Cohesion
7. Lead Off With The Essentials
8. Include A Comprehensive eLearning Course Map

Which UML diagram target system behavior specification ?
use case diagrams, interaction diagrams, state–chart diagrams, and activity diagrams are target system behavior specification.

Use case diagrams :
A use case describes the sequence of actions a system performs yielding visible results. It shows the interaction of things outside the system with the system itself. Use cases may be applied to the whole system as well as a part of the system.

Interaction Diagrams :
Interaction diagrams depict interactions of objects and their relationships. They also include the messages passed between them. There are two types of interaction diagrams -
Sequence Diagrams
Collaboration Diagrams

State–Chart Diagrams :
A state–chart diagram shows a state machine that depicts the control flow of an object from one state to another. A state machine portrays the sequences of states which an object undergoes due to events and their responses to events.
State–Chart Diagrams comprise of -
States: Simple or Composite
Transitions between states
Events causing transitions
Actions due to the events

Activity Diagrams :
An activity diagram depicts the flow of activities which are ongoing non-atomic operations in a state machine. Activities result in actions which are atomic operations.

Activity diagrams comprise of -
Activity states and action states
Transitions
Objects
Activity diagrams are used for modeling -

workflows as viewed by actors, interacting with the system.
details of operations or computations using flowcharts.
