+ – Software Development Methodologies

4 lectures 12:40

Managing complex projects wouldn't be possible without systems and rules. In this section, we'll talk about two of the most popular methodologies used for developing software systems.

What are Software Development Methodologies?

Preview 01:39

Let's take a closer look at the Waterfall model, which is being used successfully in life-control, medical and military systems.

The Waterfall Model

04:35

Waterfall may be inflexible in some cases. Luckily, Agile is here to help in such situations. Let's see how.

Agile Frameworks

04:39

Has Waterfall become obsolete? Is Agile always the best option? The answer to both questions is "No."
And here's why.

Waterfall or Agile?

+ – Core Object-Orientation Concepts

7 lectures 21:46

Programming is relatively new, yet it evolved a lot during the last few decades. This lecture is a brief walkthrough of the history of programming.

Brief History of Programming

04:08

While structured programming relies on actions, Object-Oriented programming is organized around objects. So, let's talk about objects.

Preview 02:40

OOP is all about objects. But, to create an object, we need to have a class first.

Classes

02:42

Abstraction is one of the fundamental concepts in Object-Oriented programming. This lesson will clarify the "whys" and "hows".

Abstraction

01:32

Encapsulation and data hiding are the other pillars of OOP.

Encapsulation and Data Hiding

02:39

Inheritance is a key concept in Object-Oriented Programming. Without inheritance, we’d end up redundant code over and over again.

Inheritance

03:40

Polymorphism is the final object-orientation term we need to talk about. In this lesson, we'll also use a coding example to demonstrate how polymorphism works.

+ – Object-Oriented Analysis and Design

4 lectures 13:27

How should we start creating an object-oriented system? Is there any recipe for it? In this lecture, I'm going to provide the answer.

Fundamental Object-Oriented Analysis and Design Concepts

03:20

The requirements collection or requirements analysis phase paves the road for all the other phases of the object-oriented software design.

Collecting Requirements

04:19

Once we gathered the requirements, we can feed them to the next step of the software design process.

Mapping Requirements to Technical Descriptions

04:34

Here's why we need a common design language like the Unified Modeling Language.

Why Do We Need a Common Descriptive Language?

01:14

+ – UML Basics and Fundamental Diagram Types

10 lectures 30:06

The Unified Modeling Language is a graphical notation rather than a textual programming language. In this lecture, we'll see how UML helps us in describing the structure and the functionality of a software system.

Preview 03:17

The use case diagram visualizes the functional requirements of the system. Although it's simple, it's quite powerful. Let's see how it works.

Use Case Diagrams

Preview 03:44

In this lecture, we'll delve into class diagrams, the most frequently used UML diagram types.

Class Diagrams

03:36

UML allows us control who can access the attributes and the methods of our classes. This lecture is about visibility.

Visibility: Public, Private, Protected, Package

03:30

The next logical step after identifying the key classes in our system is figuring out the relationships between them.
First, we'll talk about associations.

Associations

02:49

In UML, we use generalization to express that one model element is based on another model element.

Generalization

01:33

In this video, we'll talk about the other UML relationships: dependency, aggregation, composition and realization.

Dependency, Aggregation, Composition and Realization

02:30

UML provides dynamic diagrams to represent how objects communicate with each other. The most common dynamic diagram is the sequence diagram.

Sequence Diagrams

04:40

The activity diagram is a useful technique to represent behavioral logic.

Activity Diagrams

02:50

Statechart diagrams describe the states of an object while identifying the events responsible for the state changes.

+ – Case Study: Designing a Note-Taking App from Scratch

7 lectures 30:52

In this lecture, I’m going to illustrate the requirements collection phase through a real example.

Collecting the Requirements

02:00

Now that we've got the requirements, let's write some user stories.

Creating User Stories

02:24

In this lecture, we’re going to represent our user stories as use case diagrams.

Diagraming the Main Use Cases

03:02

Let’s create the static structure of our system. We’ll identify the main classes and the relationships between them.

Modeling the Classes and the Relationships

06:14

We'll describe the note creation scenario in the form of a sequence diagram.

Describing the Flow of Note Creation using Sequence Diagrams

02:15

I’ve got a question in the Q&A section. The student could not create associations in the use case diagram. So, here’s a quick video showing how to do that.

Thank for your videos. it's saved my life haha. switch from web developer to backend developer. I need to used UML for drawing diagram. I try to find a lot of tutorial on google, youtube. but still not clear about UML and cannot draw it properly. I spend more than three weeks on learning it from google & youtube. but end up learning here only a morning (4h). Thank for your excellent course and well explain for make me understand it well....
