Using the Web
The Internet is a worldwide collection of millions of interconnected computers and com-
puter networks that share resources. The World Wide Web (or the Web ) is a vast collection
of digital documents available on the Internet. Each digital document on the Web is called a
Web page , each computer on which an individual or company stores Web pages for access
on the Internet is called a Web server , and each computer requesting a Web page from a
Web server is called a Web client . Each Web page is assigned an Internet address, which is
also called a Uniform Resource Locator ( URL ); the URL identifies where the Web page is
stored—the location of the Web server and the name and location of the Web page on the
server. For example, http://www.course.com/catalog/default.html is a URL that identifies the
Web server (www.course.com), the location path (catalog) on the Web server, and the Web
page name (default.html). The beginning of the URL (http) specifies the Hypertext Transfer
Protocol (HTTP) , which is the data communication method used by Web clients and Web
servers to exchange data over the Internet. To view a Web page, you use a computer pro-
gram called a Web browser , such as Microsoft Internet Explorer or Mozilla Firefox. After you
start a Web browser, you enter the Web page’s URL. The Web browser uses the URL to find
and retrieve the Web page, and then displays it on your computer screen.
Each Web page is a text document that contains the necessary codes, called tags , that
the Web browser interprets to position and format the text in the Web page. A Web page
can also contain tags for links to audio files to be played, to graphics and animations to
be displayed on the screen, and to other files, which are sent along with the Web page
by the Web server. A Web page can also contain tags for hyperlinks , which connect Web
pages to other Web pages or Web sites or to a location in the same Web page. When
you click hyperlink text, the linked page opens. Hyperlinks connect Web pages through-
out the Internet.
Web pages are usually created using a programming language called Hypertext
Markup Language (HTML) . You can create a Web page by typing all the necessary HTML
tags into a text document, called an HTML document , and saving the document with the
.htm or .html file extension. You can also use a program, such as ColdFusion or Adobe
Dreamweaver, to create the HTML documents for Web pages without needing to learn
HTML. Many programs, including Access, have built-in tools that convert and export
objects, such as tables and queries, to HTML documents.
Exporting an Access Query to an HTML
Document
Tip
An intranet is an internal
company network that uses
software tools and lan-
guages, such as HTML, that
typically are used on the
Internet and the Web. The
company that manages or
owns the intranet restricts
access to it by using
passwords.
Oren wants to display the customer contact data in the qryCustomersByName query on
the company’s intranet so that all employees working in the office are able to access it.
To store the data on the company’s intranet, you’ll create a Web page version of the
qryCustomersByName query.
Creating the necessary HTML document to provide Oren with the information he
wants is not as difficult as it might appear at first. You can use Access to export the query
and convert it to an HTML document automatically.
