Web Application

Task 1

1.1 Critically evaluating the functions and advantages of web applications

As per Sudhendra, Ranganath and Nandan (2016), Generally, Web-based applications run through web browsers like Internet Explorer as well as Google Chrome etc. In addition to this, the main function of web pages is interacting with users through requesting and responding with the help of the internet (Sudhendra, Ranganath and Nandan, 2016). According to Hill, Cronk and Wickramasekera (2013), Web-based applications contribute an effective role for an organization to reduce its business costs which provides huge reliability in managing its business operations (Hill, Cronk and Wickramasekera, 2013). On the other side, sometimes, web-based applications create problems in accessing data due to a lack of internet speed and limitations of the server (Januszewski and Molenda, 2013). As per Brent (2013), it provides a better opportunity to store all data on the centralised server which gives effective data safety to ABC (Brent, 2013). According to Ghimire, and Pimbert (2013), the reduced speed of the client-server model creates problems in visiting the website of the company and it generates issues in opening the web pages. In addition to this, it affects the performance and efficiency of ABC Corporation” (Ghimire, and Pimbert, 2013). As per Wasson (2015), it provides effective compatibility to run applications on various types of platforms like Windows, Linux and Mac. This process gives effective flexibility to the management of the firm to manage its online operations (Wasson, 2015). On the contrary note, web-based applications do not support all web browsers which creates problems for many users to access different data.

1.2 Critically comparing different types of server-side and client-side scripting languages

A comparison of client-side and server-side script language is given below in the paragraph

According to Thüm, T. and et.al, (2014), client-side script-language is used to run various types of scripts on the browser. In addition to this, it takes place on the end users and the source code of web-based applications is transferred from the web server to the users over the internet. Further. Client-side scripting language runs directly in the browser of service users (Thüm, T. and et.al., 2014). On the other side, web-based applications need to be installed and enabled on the client's computer (Ghiani, and et.al., 2016).

Harley and et.al, (2013), a server-side environment which runs a scripting language in the web server. Generally, the user's request is responded to by running a script directly on the web server which helps to produce dynamic HTML pages. These codes of HTML are sent to the client browser which provides effective reliability for a user to assess its information (Harley and et.al., 2013). According to Sudhendra, Ranganath and Nandan (2016), server-side script language is utilized to give attractive websites which provide a proper interface to databases (Sudhendra, Ranganath and Nandan, 2016).

1.3 Examine web security concerns and make recommendations for security improvement

There are many Web security concerns such as hacking, cracking as well and phishing which affect ABC very badly. These threats steal the data from companies which produces huge loss of its monetary funds. Generally, viruses are another issue for website security because they hang computers and servers. In addition to this, they affect the performance and efficiency of web-based applications which also creates a bad impact on the ABC organization (Hill, Cronk and Wickramasekera, 2013). Further, security updates are the main issues which increase the threat of inappropriate activities like hacking in the corporation.

Recommendations

These suggestions can help the management of enterprises to improve web-based applications. ABC fashion firm can use web security protocols like IPV6 and firewalls which can contribute effectively to stop these illegal activities like hacking and phishing. In addition to this, corporations can use proper anti-virus and effective security applications which can help to remove viruses and malware. Further, organisations can use bio-metric security systems to stop unauthorized access by unknown people. This process can effectively help ABC organization reduce its stealing of important data from servers.

Task 2

2.1 Designing web application to meet a given requirement

ABC is a fashion organization which sells attractive clothes for all types of consumers in the United Kingdom. Generally, corporation wants to increase its clothes business in the UK market. So this online website can contribute an effective role for a firm to enhance its online business in the textile sector. As per company requirements, this website can help the ABC organization to establish a business which can help to increase its sales (Januszewski and Molenda, 2013). It contains various types of web pages like homepage, contact us, about us and products and services. Developers can consider can PHP tool as the front end and MY SQL back end to develop website of the organisation

2.2 Explaining client-side and server-side functionality in a web application

Generally, ABC organization can use various types of languages to develop appropriate fashion websites. The firm can use HTML on the client side and PHP on the server side to make a fashion website. Further, PHP provides effective reliability to developers of organizations to run the website on any platform like Windows, Linux and Mac. In addition to this, systems such as Memcache, MongoDB as well and Pusher provide effective integration which reduces many complexities of developers regarding integration of the website. By using PHP server side; it gives effective reliability to fix the web application related issues (Taei, 2013). In addition to this, using HTML on the client side provides huge flexibility for the client to assess the data very fast. Further, it produces less load as compared to another web-based language which provides effective help to manage a server of ABC in an appropriate manner. Most development tools highly support HTML which gives effective compatibility to run the fashion website of ABC on the client side (Brent, 2013).

2.3 Applying database design for use in a web application

ABC fashion organization can use SQL language to design an appropriate database of web applications. Further, this process can help the developers to link the front end and back end very easily. In addition to this, it can provide better reliability to access the database of ABC. SQL database design can help the organization to Insert, Update as well as Delete operations on the website (Wasson, 2015). These activities are represented below.

• Insert operation can help a firm to insert any type of data into the database. For example,
• INSERT INTO Consumer (Consumer Name, Contact Number, Address, City, Country)
• VALUES ('Cardinal',' John Niight', '788769756',' 40009',' London',' United Kingdom);
• Update operation can help the ABC organization to update any data in the database. For example,
• UPDATE Consumers
• SET ContactName='Rosamund pike', City='Newyork'
• WHERE Consumer Name='Rosamund pike';
• Delete operations can be used to delete any type of information from the database. For example,
• DELETE FROM Consumers
• WHERE ConsumerName='Tom Knight' AND City='London';
