E-commerce is the current approach for doing any type of business online, which uses the superior power of digital information to understand the requirements and preferences of each client and each partner, to adapt products and services for them, and then to distribute the products and services as swiftly as possible.

This project was created for third grade teachers who use the Houghton Mifflin Language Arts series and want to integrate computer software into their writing curriculum. The website created includes all the writing assignments that the students are to complete and the required software used to complete the assignment.

This study develops and applies a conceptual framework that can be used to evaluate dynamic Web platforms in order to determine a platform for teaching Web application development in tertiary institutions. The framework is specific, yet comprehensive and supported with theory and empirical experimental programming results. We first identify the concepts of Web application development and the constraints to be satisfied by a platform for teaching identified concepts. Then we establish various criteria that will enhance the teaching of the concepts. We also establish qualities and experiment that will ensure that a selected platform is easy to use, fast, portable and affordable. A spreadsheet tool is developed to apply the framework and enable users to customize the framework by varying the criteria's weights. The developed framework is tested by the evaluation of the suitability of Java Servlets, JSP, ASP and PHP with PHP emerging as a suitable platform. / Computing / M.Sc. (Information Systems)

We investigate whether usability aspects affect the design and development of the browsing experience in electronic commerce applications. The study is limited to the generic electronic commerce activities and does not address the financial perspective. As background we studied the electronic commerce domain, interaction design and information systems development methodologies. Within a quasi-experimental research design we then developed two experimental websites to test our hypotheses that the usability principles of consistency, structured information and navigation affect the users of a website: one adhering and one violating these principles. Respondents were required to record their perceptions of both using a questionnaire. We found that usability issues had a minimal influence on the perceived success of the websites. It is thus only one of many factors that needs to be considered in the design and development of a successful electronic commerce website, and cannot be treated as an isolated add-on. / Kotzé, P. / Information Science / M.

Software as a service is an emerging but important aspect of the web. WebServices play a vital role in providing it. Web Services are commonly provided in one of two architectural styles: a "REpresentational State Transfer" (REST), or using the "Simple Object Access Protocol" (SOAP.) Originally most web content was text and small images. But more recent services involve complex data structures including text, images, audio, and video. The task of optimizing data to provide delivery of these structures is a complex one, involving both theoretical and practical aspects. In this thesis work, I have considered two architectures developed in the REST architectural style and tested them on mixes of data types (plain text, image, audio) being retrieved from a file system or database. The payload which carries the actual content of a data transmission process can either be in Extensible Markup Language (XML) or JavaScript Object Notation (JSON). Both of these language notations are widely used. The two architectures used in this thesis work are titled as Scenario 1 and Scenario 2. Scenario 1 proposes two different cases for storing, retrieving and presenting the data via a REST web service. We investigate the question of what is the best way to provide different data types (image, audio) via REST Web Service. Payload size for JSON and XML are compared. Scenario 2 proposes an enhanced and optimized architecture which is derived from the pros of the first two cases in Scenario 1. The proposed architecture is best suited for retrieving and serving non-homogeneous data as a service in a homogenous environment. This thesis is composed of theoretical and practical parts. The theory part contains the design and principles of REST architecture. The practical part has a Web Service provider and consumer model developed in Java. The practical part is developed using the Spring MVC framework and Apache CXF, which provides an implementation using JAX-RS, the Java API for RESTful services. A glossary of acronyms used in this thesis appears in the appendix on page 101.
