The document describes the Model-View-Controller (MVC) software architectural pattern. MVC separates an application into three main components: the model, the view, and the controller. The model manages the application's data and business logic. The view displays the model's information. The controller interprets inputs from the user and updates the model and/or view accordingly. This separation of concerns makes the application modular, reusable, and maintainable.
General overview of Model View Controller design pattern for software architecture. Gives simple examples and also more complex examples using Spring MVC framework.

What is the DOM?
The DOM is a W3C (World Wide Web Consortium) standard.
The DOM defines a standard for accessing documents:
"The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."
The W3C DOM standard is separated into 3 different parts:
Core DOM - standard model for all document types
XML DOM - standard model for XML documents
HTML DOM - standard model for HTML documents
The HTML DOM (Document Object Model)
When a web page is loaded, the browser creates a Document Object Model of the page.
The HTML DOM model is constructed as a tree of Objects.
With the HTML DOM, JavaScript can access and change all the elements of an HTML document.

Model–view–controller (MVC) is a software design pattern for implementing user interfaces on computers. It divides a given software application into three interconnected parts, so as to separate internal representations of information from the ways that information is presented to or accepted from the user.
What Are The Benefits Of Using MVC Framework In ASP.NET Development.pptxQuickwayInfoSystems3
The Model-View-Controller (MVC) framework in ASP.NET development offers numerous advantages that contribute to the creation of robust, maintainable, and scalable applications. By promoting a clear separation of concerns, MVC enhances code organization and readability, making it easier for developers to manage and extend their projects. The framework's support for testing and asynchronous programming further enhances application reliability and performance.

Audio and video became first citizens on the Web with HTML5 the same way that other media types like images did in the past.
With the coming additions to the APIs you will be able to read and write raw data to audio files (Audio Data API) or manipulate captions in vídeos (Timed Track API).
Não é segredo que a computação em nuvem está se tornando cada vez mais popular hoje em dia e é cada vez maior em popularidade com grandes empresas como eles compartilham recursos valiosos de uma forma rentável. Devido a esta crescente demanda por mais nuvens há uma ameaça cada vez maior de segurança se tornando um grande problema. Este documento deve encontrar uma forma de ameaças de segurança que podem ser um perigo para a computação em nuvem e como ela pode ser evitada.

Model View Controller (MVC)
1.
2. • Software architecture pattern that separates the model,
the user interface and control logic of an application in
three distinct components.
3. • MVC proposes the construction of three distinct components. One side
for the representation of information, and on the other hand for user
interaction.
One model
Many Views
Many Controllers
4. The Model
Representation of domain data.
Business logic
Persistence mechanism
The View
User Interface
Interaction elements
The Controller
Intermediary between Model and View
It maps user actions – model actions
Select the view and provide
information to itself
5. It is the specific representation of the
information with which the system
operates. Logic ensures the integrity of
data and allows to derive it.
6. Represents the model in a suitable format to interact and access the data,
usually called "User Interface" (GUI Java, HTML, XML).
7. It is the link between the view and the model, is responsible for receiving
and responding to events, typically user actions and invokes changes on
the model and probably in the view.
8. • Organization
• Rapid Application Development
• Reusing Code
• Parallel development
• It presents the same information in different ways.
• The views and application behavior should reflect the
manipulations of the data immediately.
• It allows different user interface standards or port it to other
environments where the application code should not be
affected.
9. • This model is not new, it was introduced in 1987 in the Smalltalk
programming language.
• With the boom of Web applications, it has proven to be a
programming mode that fits quite well with the internet, being
both the model and the controller executed server side, and the
view on the client side executed.
10. Control Flow
1.
2.
3.
4.
5.
The user performs an action on the interface.
The controller takes the input event.
The controller notifies the user action to the model,
which may involve a change of state of the model.
It generates a new view. The view takes the data
model.
The user interface waits for another user interaction,
which starts a new cycle.
11. Controller updates the
model
View alerts controller of a
particular event
View grabs model data and
updates itself
User interacts with a
view
Model alerts view that it has
changed
12. • It applies to all types of systems
• And technologies (Java, Ruby, Python, Perl, Flex, SmallTalk,. Net, etc..)
13. • Model: The model is made by the developer.
• View: Set of objects of classes that inherit from
java.awt.Component.
• Controller: The controller is the event processing thread, which
captures and propagates the event to the view and the model.
Treatment classes of events (sometimes as anonymous classes)
that implement EventListener type interfaces (ActionListener,
MouseListener, WindowListener, etc..).
