How to Search Databases

Gopher, FTP, WAIS, Archie, Veronica, Jughead. What do all these strange terms mean? Basically, these are older tools or network services that represent different ways of searching and retrieving files on the Internet. With the development of the World Wide Web, you really don't need to know the gory details of how to use these anymore, but in case you're interested, read on.

Gopher is an application that organizes access to Internet resources using a menu-based search and retrieval system. It indexes the many databases, online library catalogs, bulletin board systems and campus-wide information services available on the Internet, by subject, type of service, or geographic location. While you are "sniffing" around Gopherspace, you are actually doing things that are not obviously visible to you, like transferring files, changing directories, connecting to computers and querying servers all over the world.

Gopher automatically takes care of finding whatever data you want, no matter where it is. You may use a dozen or more different Gopher servers in a single session, but you hardly know it. You need a Gopher client program to run Gopher, but if you don't have one, there are public Gopher sites that you can telnet to. When you get there, you log in as Gopher and then you can run its Gopher client program to do a search.

FTP stands for File Transfer Protocol, which is a widely used method of copying files from one system to another on the Internet. With FTP you can list the files in a directory and upload or download files to and from that directory.

The transfer of publicly available information is one of the most widespread uses of the file transfer capability on the Internet. Many organizations connected to the Internet provide openly accessible file transfer sites with information that anyone can obtain. Files are stored in "open" areas of computers. You access them by using FTP to connect to those systems. These are called Anonymous FTP sites because to access them you log in with the word anonymous, and use your e-mail address as the password. If you are not using a web browser with built-in FTP capability, or if you want to upload files to a remote server, you need an FTP client program.

If you go to one of the Internet software sites, like Download.com, you can find many FTP programs. We like WS_FTP for Windows and Fetch for the Mac. FTP is also built into many applications, like Web management tools, word processors and so on.

I have to sketch out the details once again before this Monday for a official presentation. But then what i want to share here with you is my experience of sharing the E-mail Support and providing computer support assistance
