• STEP 1: Set Your Goals
  1. Why do you want a web site?
  The first step is to identify the reasons for creating a website and how it will fit into your overall goals.
  You need to identify your strengths and opportunities, and how they tie with your plan of creating a web site.
  You also need to look into the threats and weaknesses that can adversely affect your plans and derail your goals.
  2. How does a web site fit your overall business plan?
• What will a website do for you and your business?
• A website may be your meal ticket and the main income source; or it may be for additional income. If you have an existing business, it can be used as a marketing tool, additional revenue source, or a springboard of an entirely different business model.
• Some of the key questions you need to ask include:
  Do you want to earn money directly from your website? Is it supposed to be profitable?
  Is your website simply for marketing purposes, with no direct revenue generation objectives?
  Will your website be used solely for customer and/or technical support?
  Is your website part of a multi-channel strategy (e.g. you run a brick and mortar store or a catalog together with a website)? Or is it a single channel strategy (e.g. you are an Internet pure play business)?
  Or will your website be an information source?

Unified Modeling Language

The heart of object-oriented problem solving is the construction of a model. The model abstracts the essential details of the underlying problem from its usually complicated real world. Several modeling tools are wrapped under the heading of the UML™, which stands for Unified Modeling Language™. The purpose of this course is to present important highlights of the UML.
At the center of the UML are its nine kinds of modeling diagrams, which we describe here.

Categories of Web Application

1.DOCUMENT-CENTERED
– Informational
read-only content is provided with simple navigation and links
– Download
a user downloads information from the appropriate server (ftp-server)
– Customizable
the user customizes content to specific needs
– examples:
• static HTML-pages, „home pages“
• web radio
• simple presentations of companies/products
2.INTERACTIVE
– content of a website is dynamically generated as response to a user request
– Form-based input is the primary mechanism for communication
between client and server
– usage of HTML-forms and Common Gateway Interface (CGI)
techniques
• radio button, string input, choice lists
– examples:
• dynamic HTML pages
• public transport schedules
• search engines
3. TRANSACTION-ORIENTED
– Complex interactions
– read and write actions
– Usage of transaction management of database systems
• Efficient and consistent data management
• structured data and queries
– examples:
• Online banking
• E-shopping
• Reservation systems
4.WORKFLOW-BASED
– support business processes („workflows“) between different enterprises or private users
– An application provides a complex service to the user, e.g.
Assists the user in determining the mortgage payment
– Prerequisite: structured flow of activities
– examples:
• Business-to-Business (B2B) Integration Frameworks
• E-Government
• Patient workflows in health care systems
5. COLLABORATIVE
– support cooperation in case of unstructured flow of
activities and high degree of communication
– „groupware“
– examples:
• support of shared information- and workspaces
– Wiki, http://c2.com/cgi/wiki
– BSCW, http://bscw.gmd.de
– Chat rooms
• E-Learning platforms
6.PORTAL-ORIENTED
– the application channels the user to other Web content or
services outside the domain of the portal application
– „single point of access“
– Examples:
• Community portals
– dedicated user groups
– Customer profiles
• Enterprise portals
– Intranet, extranet –
7. UBIQUITOUS
– personalized services at every time at every location
– Multi-platform delivery (PC, PDA, mobile phone)
– Context-dependent information
– Example:
• display of today‘s menu on end-user devices while entering a
Restaurant
8. SEMANTIC WEB
– Information available on the web
• Adequate for human understanding and
• Adequate for automatic manipulation
– „knowledge management“
• Derivation of new knowledge
• re-use of knowledge
– Example:
• Web 2.0
• Social software: wiki, Flickr, del.icio.us
• Google
