USER INTERFACE
Definition : In information technology, the user interface (UI) is
everything designed into an information device with which a
human being may interact .
Including : Display screen, keyboard, mouse, light pen, the
appearance of a desktop, illuminated characters, help messages,
and how an application program or a Web site invites
interaction and responds to it.

3 GOLDEN RULES OF USER
INTERFACE
 Place Users in Control
 Reduce Users’ Memory Load
 Make the Interface Consistent

PLACE USERS IN CONTROL
 Provide flexible interaction.
 Allow user interaction to be interruptible and undoable.

INTERRUPTIBLE AND
UNDOABLE INTERACTION

PLACE USERS IN
CONTROL
 Hide technical internals from the casual user.
 Direct interaction with objects that appear on the screen.

REDUCE USERS’ MEMORY
LOAD
 Reduce demand on short-term memory.
 Establish meaningful defaults.
 Define shortcuts that are intuitive.
 The visual layout of the interface should be based on a real-world
metaphor.
 Disclose information in a progressive fashion.

ESTABLISH MEANINGFUL
DEFAULTS.

DEFINE
SHORTCUTS
THAT ARE
INTUITIVE.

DISCLOSE INFORMATION IN A
PROGRESSIVE FASHION.

MAKE THE INTERFACE
CONSISTENT
 Allow the user to put the current task into a meaningful
context.
 Maintain consistency across a family of applications.
 If past interactive models have created user expectations, do
not make changes unless there is a compelling reason to do so.

MAKE THE
INTERFACE
CONSISTENT
 Drawer on every Page.
 Visible Cart .
 Same Header and footer
 Same Settings on Every Page.

 Definition:
An entity relationship diagram (ERD)
shows the relationships of entity sets stored in a
database. An entity in this context is a component of
data. In other words, ER diagrams illustrate the
logical structure of databases.

STATE DIAGRAM
Definition: A state diagram is a diagram used in computer science to
describe the behavior of a system considering all the possible states of
an object when an event occurs. Sometimes it's also known as a Harel
state chart or a state machine diagram

STEPS TO DRAW A STATE
DIAGRAM
Step 1 : Define States
Step 2 : Describe States
Step 3 : Draw Transitions
Step 4 : Define Transition Triggers
Step 5 : Define Guard Conditions

STEP 1 : DEFINE STATES
#Condition
#Situation
A state is a condition or situation an object might be in during
it’s life time in a system.
State

STEP 2: DESCRIBE STATES
 Give the information of the state what it will do
//When a new open
Account
With
funds

STEP 3: DRAW
TRANSITIONS
 We draw a directed line to
Indicate a change to one state
To another
State 1
State 2

STEP 4 : DEFINE TRANSITION
TRIGGERS
 We will specify what is to happen
In that transition
Ask for PIN
Number
INSERT Card

STEP 5: DEFINE GUARD
CONDITIONS
User Account
Zero Balance
 We will give a condition to go
one state to another. If condition
become true then go to next state.
If(Balance==0)

CLASS DIAGRAM
 Graphical way to illustrate relationship between classes in an
object oriented system
 Appearance varies between different drawing tools
 Describe responsibilities of a system.
 Base for component and deployment diagrams.

CLASSES
 Represented by a box
 In the simplest case , a class might be a box
with the name of the class included within it Hello UIU

CLASS FIELDS
 Fields ( data members ) of a class
added to the box between two lines
 First character in the field name
gives scope
o +for public
o - for private
Hello UIU
Message : SAD LAB

METHODS
 Methods ( member functions) go below
the class fields section
 Same scoping and typing conventions
used
- Actual semantics vary from tool to
tool
Hello UIU
Message : SAD LAB
+setMessage( m : SAD LAB)
+getMessage (): SAD LAB
+ display ()
+HelloWorld() – constructor

RELATIONSHIPS
BETWEEN CLASSES Drawn using arrows to connect classes together
-Two Categories of this Relations :
1. Generalization : Can represent relationships between the classes
themselves.
2. Association : Can represent relationships between instances of the
classes
 Multiplicity :
- Specific number ( e.g. 1)
- Range of numbers , separated by two dots (e.g. 0..1)
-Unbounded ranges ( e.g. 0..* or 1..*)

GENERALIZATION (
INHERITANCE) Shows “is-a” relationship between
classes
 Used for languages that supports
inheritance
 Child Class is a subclass of parent
class
Message
-text : String = “SAD LAB”
+getMessage(): String
SimpleMessage
+SimpleMessage (s: String)

AGGREGATION
 Weak type of : has a “ relationship
 One class contains a collection of
instances of other classes
 Key Idea : the instances of the
other class can exist independently
of the collection
MultiMessage
Message: List<Message>
+addMessage(m :Message)
SimpleMessage
+SimpleMessage (s: String)
