System analysis & Design
• User Requirements Definition: The UR stage is considered as the ‘concept' or
‘problem definition‘ stage; UR frequently derive directly from a spontaneous
idea or thought UR should be gathered based on the user needs; UR should be clarified through criticism and
experience of existing software and prototypes; UR should be approved through interviews and
surveys; UR should be realistic (clear, verifiable, complete,
accurate, feasible).

• System Requirement Specification A detailed statement of the results that a system is
requested to reach. A good specification gives a complete statement of what the system is to do,
A system requirements specification is normally produced in response to a user requirements.

Use Case Diagram
It describes the main system functions from the standpoint of an external observer.
Used during requirements elicitation to represent external behavior.
It emphasize on what the system does rather than how it.
It is created during the early stages of a project – during the analysis phase rather than during the design phase.
It provides a high-level view of what the system does and who uses it.
It provides the basis for determining the user interfaces (UIs) to the system

Conceptual (Domain) Model
A domain model illustrates meaningful concepts in a problem domain.
It’s a representation of real-world things, not software components.
It’s a set of static structure diagrams; no operations are defined.
It may show:
Concepts
Attributes of concepts.
Associations between concepts

Sequence diagrams: An Interaction Model
• An Interaction Model
• Sequence diagrams are part of the UML and are used to model the
interactions between the actors and the objects within a system.
• The objects and actors involved are listed along the top of the
diagram, with a dotted line drawn vertically from these.
• Interactions between objects are indicated by annotated arrows.
• Detail how operations are carried out
• Dynamic Diagrams
• Organized according to time • The time progresses as you go down the page
• The objects involved in the operation are listed from left to right
according to when they take part in the message sequence.
• Create a sequence diagram for each scenario

Class Diagram
A class diagram shows the existence of classes and their relationships in the logical
view of a system.
UML modeling elements in class diagrams:
Classes and their structure and behavior.
Association, aggregation, dependency, and inheritance relationships.
Multiplicity and navigation indicators.
Role names.

• Basic principle: problem partition
• Partition with regard to what
– Object - Object Oriented analysis
– Function - Structural analysis
• Data Flow Modeling (DFD)

Data Flow Modeling
• Widely used; focuses on functions performed in the system
• Uses data flow diagrams (DFDs) and functional decomposition in modeling

Steps in Building DFDs
1. Build the context diagram
2. Create DFD fragments for each scenario
3. Organize DFD fragments into level 0
4. Decompose level 0 DFDs as needed
5. Validate DFDs with user
