Client Side + Server Side

Google Web Toolkit provides tools to create and maintain complex JavaScript front-end applications in Java.
Pyjamas is a tool and framework for developing AJAX applications and Rich Internet Applications in python.
Tersus is a platform for the development of rich web applications by visually defining user interface, client side behavior and server side processing. (open source) However lesser known languages like Ruby and Python are often paired with database servers other than MySQL (the M in LAMP). Below are example of other databases currently in wide use on the web. For instance some developers prefer a LAPR(Linux/Apache/PostgreSQL/Ruby on Rails) setup for development.

Security Considerations

Web development takes into account many security considerations, such as data entry error checking through forms, filtering output, and encryption.[1] Malicious practices such as SQL injection can be executed by users with ill intent yet with only primitive knowledge of web development as a whole. Not only this, but scripts can be exploited to grant unauthorized access to malicious users trying to collect information such as email addresses, passwords and protected content like credit card numbers.

Some of this is dependent on the server environment (most commonly Apache or Microsoft IIS) on which the scripting language, such as PHP, Ruby, Python, Perl or ASP is running, and therefore is not necessarily down to the web developer themselves to maintain. However, stringent testing of web applications before public release is encouraged to prevent such exploits from occurring.

Keeping a web server safe from intrusion is often called Server Port Hardening. Many technologies come into play when keeping information on the internet safe when it is transmitted from one location to another. For instance Secure Socket Layer Encryption (SSL) Certificates are issued by certificate authorities to help prevent internet fraud. Many developers often employ different forms of encryption when transmitting and storing sensitive information. A basic understanding of information technology security concerns is often part of a web developer's knowledge.

Because new security holes are found in web applications even after testing and launch, security patch updates are frequent for widely used applications. It is often the job of web developers Chennai to keep applications up to date as security patches are released and new security concerns are discovered.
