Overview


The Structure of Web-based Applications

Blogs and wikis both offer users a simple way to publish content to the Web without the need to know HTML

HTML uses tags to instruct a Web browser how to display a Web page– Cascading Style Sheets (CSS) is a complementary

technology that specifies fonts, colors, layout, and placement





Many Web applications use a three-tiered structure that allows users to interact with the Web site– Presentation tier deals with presentation of

information– Middle tier is responsible for processing user input

• Also called the business logic tier

– Database tier is responsible for retrieving requested information


Understanding Blogs

Users update their blogs by entering new content using a blogging application– Collection of all bloggers (people who post to their

blogs) and their blogs is referred to as the blogosphere

– A permalink can be used to link to a specific article on a blog

– Blog members read and follow a blog

content





Advertising is the main source of revenue for most blogs– Leaderboard/banner ads– Skyscraper ads
