These discussions are not held live. Instead, peoplecome in, post or respond to messages, and then other people atanother time do the same. The best of this discussion softwaredoes more than simply allow people to have discussions: It canalso link those discussions to other intranet resources, suchas Web pages or even databases.<P>Intranet discussion software has its roots in Internet newsgroups,which allows people from all over the globe to participate inpublic discussions. In fact, intranets may use newsgroup technologyas the basis of their discussion software. Newsgroup discussionsare server-based, and work on a client/server model. The discussionsthemselves are on the server, while client software is used toaccess the server to read the discussions and respond to them.Many kinds of clients are used to participate in discussions.Newsgroup servers all over the world replicate the discussionsthey each hold, so that people from anywhere on the globe canparticipate by logging into a local server.<P>Intranet discussion software works in similar ways. It also workson a client/server model. The discussions themselves are hostedon servers, and client software is needed to read and participatein those discussions. Unlike newsgroups, however, most intranetdiscussion software requires that special client software be used-youwon't be able to use just any discussion client. Intranets willoften standardize on certain discussion software that's designedfor specific server software.<P>Intranet discussion servers, like their Internet newsgroup servercounterparts, replicate their discussions so that people acrossan entire intranet can participate. A server may host all discussionsin a particular department or division; that server then replicatesits discussions at pre-set intervals with discussions in otherdepartments and divisions, so that everyone can participate inall discussions.<P>The most powerful discussion software goes beyond mere talk. Itwill, for example, allow someone to place a link to a Web pagein a discussion. Then, when anyone in the discussion clicks onthe link, a Web browser is launched, and the site is visited.This makes it easy for people to get feedback on sites they'redesigning, or access information contained in those sites. Similarly,programming tools like Java can be used to link discussions tointranet resources such as databases, so that in discussions peoplecan access corporate data and comment on it.<P>Some discussion software also lets intranet administrators setsecurity levels for different discussions. Certain discussionsmay be open to the entire company, while others are password-protectedso that only certain people can see them. Some discussions caneven allow everyone to read them, but only certain people to participate.<P>Discussion software allows people to instantly communicate, buildsa sense of community, and lets people brainstorm in ways neverbefore possible.<H2><A NAME="UsingIntranetDiscussionSoftware"><FONT SIZE=5 COLOR=#FF0000>Using Intranet Discussion Software</FONT></A></H2><P>Intranet-based discussion software allows people across an intranet-nomatter where they are located-to participate in collaborativediscussions. This discussion software offers far more than thenewsgroups on the Internet offers. It allows links to Web pagesand corporate resources such as databases; gives intranet administratorstools to create private discussions and to moderate discussions;and enables intranet programmers to add features using programminglanguages such as Java.<UL><LI>Discussion software is hosted on intranet discussion servers.These servers handle the processing of all messages. When someonereads a message, they're reading it from a server, and when theyrespond to a message, they're sending it to the server.<LI>Discussion software can link thousands of employees on a globalintranet. Because of the distances involved and the computingresources required, it would be impossible for a single serverto host all the discussions. Instead, each server handles a specifiedgroup of people. Each server replicates the discussions it hostson all other servers on the network, so that everyone on the intranetcan participate with discussions with each other by interactingwith their own local server.<LI><I>Message threads</I> are a basic and fundamental part ofdiscussion software. Message threads are focused discussions abouta single portion of a larger topic. For example, a discussionabout marketing plans may have separate threads for marketingplans for last year, this year, and next year.<LI>Intranet discussion software can be integrated with Internetnewsgroup discussions. The intranet discussion servers can replicateInternet newsgroup discussions on them, which means that intranetusers can participate in Internet discussions from their own discussionsoftware and server, without having to go out to the Internet.<LI>Some discussion software allows intranet administrators toset up a "discussion firewall." This firewall wouldallow people inside the intranet to see Internet newsgroup discussions.When they respond to them, however, those responses will onlybe able to be read by people inside the intranet. The responsewon't be allowed to go out to the Internet.<LI>Some intranet discussion software will read HTML and allowfor links to other intranet and Internet resources, in particular,the World Wide Web. For example, a link to a specific Web sitecan be put into a message. Whenever someone clicks on that link,a Web browser will be launched, and the site will be visited.<LI>Discussion software gives intranet administrators a greatdeal of control over discussions. It allows for administratorsto moderate discussions, and weed out inappropriate messages,as well as password-protect certain discussions. So, for example,there can be public discussions set up as well as private discussions.<LI>Discussion software can include programming tools, or it canallow developers to use programming tools such as Java to customizethe software and better integrate it into the intranet. For example,a Java applet can be built into discussion software that willallow people to query a database and get results directly froma discussion. This, for example, would allow someone to placereal-time information about corporate sales, that changes as thedata changes, directly into a sales discussion area.</UL><HR><CENTER><P><A HREF="ch23.htm"><IMG SRC="PC.GIF" BORDER=0 HEIGHT=88 WIDTH=140></A><A HREF="#CONTENTS"><IMG SRC="CC.GIF" BORDER=0 HEIGHT=88 WIDTH=140></A><A HREF="contents.htm"><IMG SRC="HB.GIF" BORDER=0 HEIGHT=88 WIDTH=140></A><A HREF="ch25.htm"><IMG SRC="NC.GIF" BORDER=0 HEIGHT=88 WIDTH=140></A><HR WIDTH="100%"></P></CENTER></BODY></HTML>⌨️ 快捷键说明
