Choosing the best web application development framework

I’ve discussed web frameworks before and how they can help in rapid development. In this post, I’m presenting some general guidelines around selecting the best web development framework, based on your requirements, in the the preferred language: Java, Ruby, PHP, Python. The main criterion is evaluating the non-functional requirements it provides out-of-thebox, which can greatly aid rapid development.

What to look at in a framework?

You should know how the design considerations mentioned below are addressed by the frameworks you are evaluating. Depending on the business needs, some might be redundant, but tend to provide a holistic view of the framework’s capability.

Scaffolding code: What is the ETD to get a web-form with basic CRUD running?
Does it offer the flexibility to choose between convention & configuration?
How is input data validation achieved?
Is the View layer simplified with a template engine?
Does it employ object-oriented design patterns? and demand OOP?
Does it follow MVC (Model-View-Controller) pattern? How is routing (URL management) achieved?
What ORM tools (object relation mapper) does it support?
Does it have built-in support for multi-tenancy?
Does it support I18n & L10n out-of-the-box? (Internationalization & Localization)
How is Authentication & Authorization managed: inbuilt, using a module or plug-in?
Does it allow rapid development/deployment in line with Agile principles?
Are there cases of proven success for enterprise class applications?
What is the performance benchmark vis-a-vis other frameworks?
Is there in-built support/plugins for caching, unit & scenario testing?
Is it easy to debug applications, and if possible with in-built support through an IDE?
Associated costs & TCO: to build developer & infrastructure expertise, hosting, licensing, support?
Does the licensing permit free use for all purposes and the right to modify code as necessary?
Does it have a clear product roadmap, sufficient documentation & an active community?

The decision

Don’t get carried away by flashy white-papers, classy developer events or generalized case studies. Your application is going to be different (a reason why you’re building that product in the first place) and while it is good to use guidelines, you need to see what fits your requirement best. Take a weighted approach to evaluating a framework based on the evaluation criteria above and make sure you have enough reason to be convinced.

Rapid application development & web frameworks

Rapid Development

Over the last decade, there has been a massive growth in the number of web-based applications. For every category – email, collaboration or knowledge management to name a few – there are a large number of applications available, and new ones on their way. This has created extreme competition in the market with each application claiming to be better than the other. Even if a new concept exists that is strong enough to drive the market, time-to-market is a crucial factor that will decide the success of the product.

To address this, a rapid application development strategy needs to be in place so that the product and incremental features can be delivered at the expected rate which is dictated by the market & customers. Besides this, development needs to also follow an agile model so as accommodate ever-changing business requirements. This is especially true in the case of product development, where a single product must fit multiple customers with varying business requirements, and the classic waterfall model can lead to complete failure.

Web Application Frameworks

A web application framework (‘framework’ hereon) is a software framework that is designed to support the development of dynamic websites, Web applications and Web services by providing core, non-functional features out-of-the-box. A framework streamlines application development by automating many of the patterns employed for a given purpose and thus resolve the overheads associated with common activities performed in web development.

A framework also adds structure to the code, prompting the developer to write better, more readable, and more maintainable code. It promotes code reuse through the use of libraries for database access (using ORM), template engines, session and user management, logging, internationalization, etc.

Framework selection (we’ll elaborate this in the next post) is thus crucial in delivering the required functional & non-functional requirements within stipulated timelines. Non-functional are the primary influencers Continue reading Rapid application development & web frameworks →

Microsoft tech-ed 2009 India

Overview

The 3-day Microsoft event was organized at the plush Hyderabad International Convention Centre attached to the Novotel Hotel. The arragement was near perfect: with over 2000 heads moving, there was no wriggling in the corridors or waiting at food counters and washrooms. Each day started with a key note, one technical and the other non-technical {usually arts, by Resul Pookutty & Agnee}, and ended with Demo Extravaganza featuring Live demos of new products like Office 2010, Windows 7, IE 8 & MS Robotics Studio. Sessions under several tracks, well-defined for a individual’s job profile – like developer, architect, IT manager, etc, were held in parallel. Announcements, like the release of new controls in the AJAX toolkit, developer extensions for PHP were part of regular sessions. Several partners like Intel, F-Secure, Polycom, etc were showcasing products, and their integration with the Microsoft product line at their pavilions.
