Find Class Codes and Use Them in a Search?
TOPIC: Generally speaking, there are two approaches to locating test and evaluation information: the single or multiple database search. The single database approach allows you to take advantage of a database's unique characteristics. Inspec® (File 4) is a perfect example of a database with powerful additional indexing that enables you to find technical papers that deal with information on testing results. This database contains Classification Codes that identify each subfile and topics within the subfile.
For this example we want to locate the most current information on the test procedure "fault diagnosis" and telecommunications.
COMMAND SUMMARY
BEGIN 4
SELECT FAULT()DIAGNOSIS?
SELECT S1 AND UD=9999
HELP CODES 4
SELECT S2 AND CC=B6
TYPE S3/3/1

HOW TO...
1. BEGIN File 4, an all inclusive database for technical topics.
2. SELECT keyword(s) and limit the search using UD=9999.
UD= is the prefix for Update Code. To retrieve only those records from the most recent update to the database, enter SELECT UD=9999. |
 |
3. Using the HELP command, you can see the class codes available in the database to help focus the search to a specific topic.
Note that the coding is divided by specific subject areas, with individual topics listed for a subject.
For this topic we'll focus on Communications. |
 |
4. SELECT Set 1 (S1) and the class code for communications to focus fault diagnosis to this area.
Note: Portions of the list are omitted from this display. |
 |
5. TYPE a record to make sure the search is on target. The title indicates this is an appropriate article.
Note the DOI. By clicking the DOI link, you can retrieve the entire paper if you have a subscription to IEEE.
6. Click Links > Display > Type Full Record to see the complete record, including an informative abstract.
