Buy a laptop for coding and programming Buy a programming booksWe are here to give you a full tutorial of making project report for any project of software. This project report or presentation will make your project easily understandable to client or user. In this, you represt your project by the help of daigrams i.e. class diagram, DFD diagram, ER diagram, Sequence diagram, Use Case dagram etc. We will cover all these topic in my tutorial. So, lets start the tutorial.
Classes represent an abstraction of entities with common characteristics. Associations represent the relationships between classes. In Example, classes with rectangles divided into compartments. Write the name of the class in the first partition, Enter the attributes in the second partition, and write all the operations into the third.
classes initiate and control the flow of activity, while passive classes store data and serve other classes. Active Class is show with thicker border.
Visibility markers are used to signify who can access the information contained within a class. Private visibility, denoted with a - sign, hides information from anything outside the class partition. Public visibility, denoted with a + sign, allows all other classes to view the marked information. Protected visibility, denoted with a # sign, allows child classes to access information they inherited from a parent class.
It represent static relationships between classes. Write association names above, on, or below the association line. Use a filled arrow to indicate the direction of the relationship. Place roles near the end of an association. Roles represent that two classes see each other.
Place multiplicity notations near the ends of an association. These symbols indicate the linking of instances of one class from another. For example, one company will have one or more employees, but each employee works for just one company.
Constraints lies inside curly braces {}.
Composition is a special type of aggregation that denotes a strong ownership between Class A, the whole, and Class B, its part.
Illustrate composition with a filled diamond.
It is also called as shared association.
Composition example here every car has a engine
Whereas, Aggregation Use a hollow diamond to represent a simple aggregation relationship, in which the "whole" class plays a more important role than the "part" class, but the two classes are not dependent on each other.
Aggregation example here cars may have passengers,they come and go.
Generalization is also called as inheritance which means (is-a) reltionship or inherit the property of one class in another class. For example, Honda is a type of car. So the class Honda would have a generalization relationship with the class car.
