WEB BROWSERS

DATA BASE

• NETSCAPE
• MS I.E.

• WEB SERVER and
• APPLICATION SERVER
• MS I.S.
• UNIX (APACHE)
• ASP, JSP

How (Module II) a Server-side applications works

• 1. request is received by www server MS internet
  server

9
Terms

• HTML Forms (Hyper Text Mark-up Language)
• Most HTML documents present information to the
  reader. There are situations however, when you
  must first get information from the user before
  you can provide the information they need.
• HTML commands used in form processing may be
  ACTION (point to a cgi program) and MEHTOD
  GET / POST

10

• 2. IS server Loads
• API (Httpobdc.dll)

11
Terms

• API (Application Program Interface)
• A set of routines, protocols and tools for
  building software applications. An API should
  make it easier to program by providing building
  blocks for final assembly.
• Example httpodbc.dll

12

• 3. Httpodbd reads the IDC file
• A. A data source is specified.
• B. An HTX file specified.

13
Terms

• IDC (Internet Database Connector)
• Is a ASCII file (text)
• Connects to the ODBC
• Executes the SQL statements
• Fetches the data from the database
• merges that data into an HTX (HTML) file
• HTX (HTML Extension File)
• Is an HTML file with some additional tags
  enclosed by ltgt which the IDC file uses to add
  dynamic data to the document. Visual Basic

14

• 4. The IDC file connects to the data base ODBC
  executes the SQL statement(s).

15
Terms

• ODBC (Open Data Base Connection
• Standard Database access method developed by
  Microsoft. ODBC makes possible access from any
  database to any application regardless of which
  DBMS is handling the data. Both applications and
  DBMS must be ODBC compliant.

16

• 5. The IDC fetches the data from the database and
  merges it into the HTML Extension file (HTX)

17

• 6. The IDC sends the merged HTML file back to the
  web server and then to the client browser.
