Web technologies

The World Wide Web continues to provide a foundation for the development of a broad range of increasingly influential and strategic technologies, supporting a large variety of applications and services, both in the private and public sectors. There is a growing need for management and decision makers to gain a clearer understanding of the application development process, from planning through to deployment and maintenance. This module will give you an insight into architectures, protocols, standards, languages, tools and techniques; an understanding of approaches to more dynamic and mobile content; and demonstrate how you can analyse requirements, plan, design, implement and test a range of web applications.

Modules count towards OU qualifications

What you will study

Over the last few years the internet and the World Wide Web have provided the basis for the development of a range of strategic business solutions.

As web technologies have entered the mainstream of IT development a wide range of applications in sectors such as marketing, selling, purchasing, banking and publishing have been deployed, positioning the Web in the relationship between providers and users.

This module starts with a focus on the foundations of web applications, including protocols, standards and content handling. It builds on these by exploring application architectures, components and alternative application designs before considering how applications and content can be made more dynamic and mobile.

The module is made up of four blocks and a project. 

Block 1 Foundations of web technology: this block covers the basic technologies on which the Web is founded. Aspects covered include: historic development of the Web; 'architecture' and basic client server architecture; protocols such as HTTP; content markup (HTML, XHTML, CSS, XML) and issues of accessibility and usability; standards and standardisation organisations (W3C, Internet working group); and security (firewalls, HTTPS, certificates).

This block of the module covers all of the basic foundations on which the remainder of the module builds.  You may already be familiar with some of these areas, especially if you have studied My digital life (TU100), but this block ensures that all students can gain comparable insight.

Block 2 Web architectures: this block develops 'architecture' by exploring different approaches and their properties as well as considering components (databases, registries etc.) which are used in different approaches and examining the nature of different server and client side languages. In addition, in this block you’ll consider other aspects related to architecture such as scalability and reliability. 

These aspects include; tiered, service orientated, and network architectures; the role of the database; web services; registries; scalability; reliability; approaches to security (cookies, certificates etc); and server and client side implementation languages (proprietary and open source).

While this block considers a range of programming languages and their roles in developing applications, it does not teach programming and you are expected to have already acquired these skills.

This block includes both JavaScript and PHP programming activities. All the code required to produce a simple web application is provided and explained, but you should be prepared to utilise and adapt the examples in simple ways.

Block 3 Mobile content: this block examines the trend toward more portable content and content customisation and also explores mobile content and applications. It considers aspects such as Web 2, content streaming (RSS), content manipulation (DOM, XSLT etc) and approaches to delivering content to mobile devices. You will also undertake the development of a mobile application using Google App Inventor.

Block 4 Developing applications: this block explores how applications are planned, designed and developed by IT professionals, examining project planning, application design, development environments and tools as well as application deployment and maintenance.

Project: at the end of the module, you will carry out a substantial project drawing on earlier work on case studies and applying the skills and techniques from each block.

In addition, using three case studies, you’ll examine aspects of real world web applications.

  1. The Open University Running Club (OURC) – in the first case study you’ll follow the development of a web presence for a small professional organisation, from the requirements collection stage to deployment of the finished application.
  2. parkrun – next, you’ll examine the more challenging requirements and approach adopted by a not-for-profit organisation which helps community volunteers organise timed 5km runs in public spaces across the UK and beyond. This decentralised organisation has a web presence for organising and publicising events as well as receiving and publishing race results.
  3. London 2012 Olympics – in this final case study you’ll examine the provision of an internet presence for this high profile event that posed a particular set of problems in terms of meeting the expected level of demand for event information, results, news and multimedia feeds. The provision also had to support a diverse audience with differing needs; those attending events, the English speaking nation and a very large world-wide audience.

All three case studies are provided as multimedia content with text, diagrams, pictures and video (transcripts are also provided).

Web technologies is one of the modules listed as a possible prerequisite for the Accreditation of Certified Practitioners 2 (TM227).

Vocational relevance

The module helps develop important skills which are particularly relevant to the workplace, such as written communication skills, information literacy, independent learning and critical analysis.

In an IT context the module will provide practitioners with relevant experience, skills and insight into a range of important aspects, such as the source and appropriate use of standards, appreciation of the application life cycle from design to decommissioning, and the range of current approaches to web application design and implementation.

Teaching and assessment

Support from your tutor

You will have a tutor who will help you with the study material and mark and comment on your written work, and whom you can ask for advice and guidance. We may also be able to offer group tutorials or day schools that you are encouraged, but not obliged, to attend. Where your tutorials are held will depend on the distribution of students taking the module.

Contact our Student Registration & Enquiry Service if you want to know more about study with The Open University before you register.

Assessment

The assessment details for this module can be found in the facts box above.

You must use the online eTMA system to submit your tutor-marked assignments (TMAs).

The end-of-module assessment (EMA) is an individual project.

Future availability

The details given here are for the module that starts in October 2014. We expect it to be available once a year.

Regulations

As a student of The Open University, you should be aware of the content of the Module Regulations and the Student Regulations which are available on our Essential documents website.

Course work includes:

3 Tutor-marked assignments (TMAs)
End-of-module assessment
No residential school


Entry

This is an OU level 2 module and you need to have a good knowledge of the subject area, obtained either through OU level 1 study, from equivalent work at another university or from experience as an IT professional.

You should be experienced in using a computer for working with documents, spreadsheets and accessing the internet and you should be able to install software on your computer. You will also need a good standard of academic English appropriate for this level of study.

You must be familiar with basic programming concepts (conditionals, loops, functions,arrays etc) and writing small programs in some language. The  programming skills developed in the OU level 1 module My digital life (TU100) or the OU level 2 module Object-oriented Java programming (M250) would be ideal preparation if you are not familiar with basic programming.

If you would like to know more about this module please see our sample materials. These pages provide some insight into a small part of this module and will allow you to be better informed about the content prior to enrolling.

If you have any doubt about the suitability of the module, please contact our Student Registration & Enquiry Service.

Preparatory work

If you are returning to study you may find it helpful to look at the Study strategies section of our Skills for OU Study website and to read a suitable book such as The Good Study Guide by Northedge, (The Open University, 2005).
