Web application is a computer program (more than a website) that uses browser interface and web technology to deliver over the internet. it uses both server-side script(PHP and ASP) and client-side script (JAVA and HTML) to present information to users. The website has moved out of the days of static text and graphics to the era of dynamic personalized for individual users. Web application has dynamic content based on tracking users' behavior and security consideration. This allow users use shopping carts, online forms, transmission of customers sensitive data to be used immediately and recurrently, share information etc. regardless of the location or device
Web application work with all type of browser interface as a client on internet and so this as reduce the maintenance as it is not needed to have different browser on desktops to carry out task on internet.
Web browser can download and install other clients when there is a complex task that web browser alone cannot execute.
Web applications perform more than browser and server interaction, they also interact with other back-end servers, databases and legacy systems. It acts both client and server when communicating with neighbors and browser, web server, application server, database and legacy system etc.
HOW WEB APPLICATION WORKS
Web applications consist of browser interface, network and web server. Browser interface asks websites from a server. The application codes are in client side script (JAVA and HTML). Web server ranges ASP.NET, ASP and ColdFusion, PHP and JSP
The protocol and languages associated with web application are HTTP (hypertext transfer protocol) and HTML (hypertext markup language) which is the basics of website creation. It also involves other internet protocols like telnet, FTP, SMTP, IMAP, XML, databases and multimedia information.
Miracle web technology an Indian web application builder have a good knowledge of HTTP, HTML, JAVA script, XML, databases, graphics design and multimedia, we can meet all your desires in web app building.
Examples of website application are Google apps, yahoo, online form, word processors, video and photo editing, Gmail etc.
Features of a web application :
A good website application must
- Interpret and route users request
- User application control
- Data enable access
- Access and modify content
- Customers response
- Transmit formatted response
- Record application usage
The type user of a website application should be defined before the application developing starts i.e (general public, authorized user, free trial access, administrator), separate the application into specific areas and identify users for each area. Links activated when login or registration form is submitted should be done on a secure connection.
Choose an internal administrative function early to protect the site from unauthorized users. Make a different web server for the functions not accessible outside your firewall, in your firewall create a secure SSL connection to access the server and only explicitly authenticated users to access the functions.
Consider activities that will be taking place with your application and determine the ones to be recorded and the extent of recording. Do not log private information like credit card numbers as you encrypt this information you also encrypt when recording for logging purpose. Logging service should be selectively enable and disable message recording to avoid cluttered log.
Database server should be placed behind the firewall for security on your database, avoid default user id and password when using relational database management system. Use separate data source configuration for read only from internal pages for maintaining the database.
Benefits of a Web Application
Web applications functions on multiple platforms not minding the device once the browser is compatible.
The Same version without compatibility issues is accessed by all users.
No hard drive installation, no space limitation.
Software piracy is reduced in subscription-based web applications.
Business and end user's cost is reduced due to less maintenance required from business and lower requirement from end user's.
WEB SECURITY ISSUES
Web applications have a number of security issues from improper coding, vulnerabilities, hacker gain direct and public access to database. Database contains majorly valuable information, this makes it target of hackers. Websites deliver required information to visitors from the database, so if web application is vulnerable to hacking then the information is at risk.
Web application must be available 24hrs and 7days in a week to allow users have access to their required service. Firewalls and SSL cannot protect web application from being hacked because the website access is open to the public. Most web applications are custom-made which is more susceptible to attack. All you need to do is to get a web vulnerability scanner
