DIALOG is one of the largest online databases. DIALOG |
currently provides access to over 250 databases containing a |
total of over 100 Million records. The range of information |
available is enormous. |
BEGIN: |
The BEGIN command starts a search and tells Dialog which |
database you want it to check out. The BEGIN command is followed |
(without a space) by the file number of the database you want. |
Either of the following ways could get you into the file 229 |
(Drug information): |
Begin229 |
or |
B229 |
Dialog will then put the date, the time, your user number, |
and what it costs for the database you just left. For example, |
if you move from ERIC (file 1) to Management Contents (file 75) |
it would look like this: |
------------------------------------------------------- |
? b75 |
28sep86 13:59:25 User08331 |
$0.10 0.00 Hrs File1 |
$0.02 Uninet |
$0.12 Estimated Total Cost |
File75:Management Contents - 74-86/Sep |
(Corp. Management Contents Inc.) |
Set Items Description |
___ _____ ___________ |
------------------------------------------------------- |
EXPAND: |
The EXPAND command is used to pick keywords for a search. |
You can search for any word; but knowing how common a word is |
gives you a good idea where to start your search. |
All databases have a index of searchable words. You can see |
if there are any words of the same spelling to a keyword you want |
to search for. For example: |
------------------------------------------------------- |
? Expand Drink |
Ref Items Index-term |
E1 1 Drina |
E2 1 Drinfeld |
E3 31 *Drink |
E4 2 Drinkers |
. . . |
. . . |
. . . |
E12 3 Dripping |
------------------------------------------------------- |
The word -more- at the bottom of the screen means that |
typing Page or P will display another screen of information. |
SELECT: |
When you find the word you want to search for, you use the |
SELECT command to tell the database what to search for. The |
SELECT command can be followed with one or more search terms. |
SELECT STEP: |
The SELECT STEP command works just like the SELECT command, |
except the files it finds are listed separately. |
------------------------------------------------------- |
? SS television? OR tv |
1 21347 TELEVISION |
2 6376 TV |
3 22690 1 or 2 |
? SS s3 AND violen? AND child? |
4 1680 VIOLEN? |
5 20577 CHILD? |
6 38 3 AND 4 AND 5 |
------------------------------------------------------- |
TYPE and DISPLAY: |
There are two commands, TYPE and DISPLAY, that you can use |
to look over the information you have found. The difference is |
the TYPE command causes a non-stop list of the information. The |
DISPLAY lets the information to list a page at a time, you have |
to type PAGE or P to see the next page. |
DIALOG offers nine formats to display retrieved files. |
