frameworks

What is a Web Framework ?
➜A web application framework is
a type of framework specifically
designed to help developers build
web applications.
➜These frameworks typically
provide core functionality common
to most web applications, such as
user session management, data
persistence, and templating
systems.
➜By using an appropriate
framework, a developer can often
save a significant amount of time
building a web site.

Features
Data Persistence
A core feature of all web applications is their need to store information and build web pages based on
stored information. Unlike a set of static pages, most web application pages are dynamically generated
from persistent data. (One notable exception is the caching of dynamic pages to improve
performance.) For example, a publisher will type an article on an administrative web page, with
multiple fields for article body, title, author, etc. That page will later be dynamically generated when a
user requests the article from the web application. This allows each article to be templated the same
and lets a publisher edit content without knowing HTML or having to edit files directly on a server.
Obviously each web application has its own needs for the exact data structures to persist. A framework
can assist in data persistence with a variety of features:
•A consistent API to access multiple data storage systems
•Automatic or simplified storage and retrieval of data objects, such as with ORM
•Core business object structure, so all data, even across multiple systems, will have a consistent basic
interface
•Performance enhancements, such as caching above the database layer
•Data integrity checks, such as validating relationships or confirming required fields are filled
•SQL building

Features
Session Management and User Authentication :
Static public websites can typically treat each visitor as completely anonymous.
Web applications, however, often require user accounts and persistence of
information across page views. Some web server and runtime configurations
provide basic session persistence, but user account management and application
specific logic need to be built on top of it. Frameworks can provide generic
user accounts, sometimes extendible, so people can register, login, and reset
passwords. They can also provide user management for administrators.

Features
Security
•Sometimes web application pages are only to be made visible to authenticated
users. Frameworks can automatically check and require authentication before
generating a page.
•Once an end user is authenticated, a framework can check the specific
permissions for that user. These permissions may be managed in a variety of
ways. A framework might provide role-based access control, or any of a variety
of other security features. These are typically managed by a developer in code
or a site administrator through an administrative interface.
Caching
•To improve web application performance, web developers will often cache certain
content so it does not need to be regenerated on each page request.
Frameworks can offer a common interface to disk or database storage of cached
content.

Features
Templating
A framework may provide one or more templating systems or engines with
consistent interfaces for developers. Most often the framework will make available
developer-defined fields or data structures available within templates (i.e. push).
Conversely a templating system may request data back through the framework
(i.e. pull).
The templating system may be something as simple as keyword replacement or
may be robust enough to automatically generate content such as form fields
from parameters.

Features
Administrative Interface
It's very common for dynamic web sites to need a section specifically built for
site administrators. Here the site can be configured and data can be altered.
Administrators might create user accounts, manage permissions, change page
content, generate reports, or anything else as required.
Web application frameworks can assist in building administrative interfaces by:
Generating a navigation structure
Providing common interface elements to form fields, such as a date field with a
calendar
Automatically generating edit and list pages from persistent data structures;
developers will often define the basic fields or desired interfaces and these will
be built into a page by the framework.

Framework

View
➜The view in MVC is the presentation layer.
➜This is what the end user of a product will see
and interact with.
➜The view doesn’t consist of business logic in
most clear designs.
➜The interface is fit for purpose and is the area
of interaction. Therefore you could simply output
HTML for consumers to interact with or output
SOAP/XML for businesses to interact with.
➜Both use the same business logic behind the
system otherwise known as the models and
controllers.

Controllers
➜The controller is where the magic happens and defines the
business application logic.
➜This could be where the user has sent a response from the view,
then this response is used to process the internal workings of the
request and processes the response back to the user.
➜Taking a typical response where a user has requested to buy a
book. The controller has the user id, payment details, shipping
address and item choice. These elements are then processed through
the business logic to complete a purchase.
➜The data is passed through the system into the model layer and
eventually after the entire request satisfies the business definitions,
the order is constructed and the user receives their item.

Models
➜The models in MVC are the bottom most layer and handle
the core logic of the system.
➜In most cases this could be seen as the layer that interacts with
the data source.
➜In systems using MVC, the controller will pass information to
the model in order to store and retrieve data.
➜Following on from the example above controller definition, this
is where the order details are stored.
Additional data such as stock levels, physical location of product
of the book amongst many things are all stored here.
If that was the last book in stock ordered, the next request for this
item may check if it’s available and disallow the order as the item
is no longer available.

Benefits of MVC
➜Different skill levels can work on different system levels. For example designers can work on the
interface (View) with very little development knowledge and developers can work on the business
logic (Controller) with very little concern for the design level. Then they simply integrate together on
completion.
➜As a result of the above separation projects can be managed easier and quicker. The designer can
start the interfaces before the developer and vice versa. This development process can be parallel as
opposed to being sequential therefore reducing development time.
➜Easy to have multiple view types using the same business logic.
➜Clear route through the system. You clearly know where there different levels of the system are.
With a clear route of the system, logic can be shared and improved. This has added security benefits
as you clearly know the permitted route from the data to the user and can have clear security checks
along the route.
➜Each layer is responsible for itself. (Relates to point 1) This means that you can have clean file
structure which can be maintained and managed much easier and quicker than a tightly couple
system where you may have lots of duplicate logic.
➜Having a clear structure means development will be more transparent which should result in
reduced development time, maintenance problems and release cycles if applied properly.
