1. Web Frameworks, APIs and Final Thoughts Class Twelve: February 20, 2013
2. Web Application Frameworks Designed to support the development of dynamic websites, web applications, web services and web resources. Aims to alleviate the overhead associated with common activities performed in web development. Gathering libraries for database access, caching, and session management (plus much more), and they often promote code reuse.
3. Web Application Frameworks Ruby on Rails (Ruby) Django (Python) CakePHP (PHP) ASP.NET MVC (ASP.NET, e.g. C#)
4. Framework Feature Examples Caching The caching of web documents in order to reduce bandwidth usage, server load, and perceived "lag". Security Authentication and authorization, enabling the web server to identify the users of the application, and restrict access to functions based on some defined criteria. Database Access Many web application frameworks create a unified API to a database backend, enabling web applications to work with a variety of databases with no code changes, and allowing programmers to work with higher-level concepts. Form Validation
5. Frameworks and MVC A software architecture pattern which separates the representation of information from the user's interaction with it. The model consists of application data, business rules, logic, and functions. A view can be any output representation of data, such as a chart or a diagram. The controller mediates input, converting it to commands for the model or view.
6. Frameworks and MVC Sound familiar?
7. Application Programming Interface “Windows to the code.” Expose some of a program's internal functions to the outside world in a limited fashion. Defines exactly how a program will interact with the rest of the software world.
8. Application Programming Interface In practice, most often an API is a library that includes specifications for routines, data structures, object classes, and variables. Sound familiar? Dronestagram
