Advanced Web Technologies By: Faraz Ahmed

Contents 0 Course Outline 0 Architectures 0 HTTP

Course definition[1] 0 This course would deal with the advanced techniques for constructing better, efficient and robust web apps. It would briefly touch upon the major concepts ranging from simple HTTP to advanced semantic web.

Stage 1 0 Introduction to Web applications and review of basic concepts: client-server architecture, three- and n-tier models, static versus dynamic pages, server- database connectivity 0 Client-side technologies: HTTP protocol, HTML and related (CSS, JavaScript, etc.) 0 Using formal methods in the development of Web applications 0 The Model-View-Controller (MVC) paradigm 0 Web Services using RESTful

Stage 2 0 Introduction: Semi-structured data. 0 XML: core concepts 0 DTDs, a simple schema language for XML documents 0 XPath, a navigation language for XML documents 0 XSLT, a transformation language for XML documents

Stage 3 0 Introduction to the Semantic Web 0 RDF and RDF-Schema 0 Basics of knowledge representation and informal introduction to OWL 0 Protégé

Client Server Architecture[2]

3-Tier Architecture[2]

HTTP 0 Abbreviation for ? 0 A web crawler –user agent 0 Stateless protocol

Maintaining State 0 Sessions 0 Cookies 0 Passing data at each request-response cycle
