Hello folks. We hope that you have been following along and more importantly this information has been helpful to you in some way. As always we are trying to add as much content on this site as regularly as possible so that readers can easily follow along and keep up the enthusiasm for learning.
In that spirit, we will keep on going further with another post in the ‘Audit Command Language Tutorial for Beginners’ series. In this post we will be discussing the Classify command. The Classify command is among one of the most frequently used commands in most ACL projects. The Classify command simply displays all the unique values along with the count of total occurrences of each of the unique values. This result is mostly show on the screen and/or it can be printed in the logs as well.
The Classify command clearly bares a lot of similarity to the the summarize command. The major difference between the two is that, when a data set is summarized, we are not sorting the data file and no additional fields besides the key field (the field on which data is classified) and any subtotal fields are allowed. Also, the Classify command is faster than a summarize if we simply want to extract the unique values because it doesn’t bother with presorting the data, which is a requriement for summarizing any data set.
Let us now explore how to actually use the command. As all things in Audit Command Language, this operation can also be performed using the GUI of the tool and via scripts. to leverage the GUI open the table and simply go to the menu, choose ‘Analyze’ -> ‘Classify…’. A pop window should pop up like shown in the screenshots below:
In the above screenshot, we can select the one field on which we wish to classify the data, the subtotal fields and the any ‘IF’ conditions that we may want to apply in order to filter out the data.
If we move towards the ‘Output’ tab, we get the options to choose the output format i.e. whether the output from the classify command would be provided on screen or in a new table. Depending on the selections that a user would make, we get a small changes to the scripts. For the above set up the Audit Command Language Script would come out as:
CLASSIFY ON WorkDept SUBTOTAL Gross_Pay TO “test.FIL” OPEN
For more detailed explanation, we urge you to view the video demonstration of the Classify command. See below:
Since this command is so useful, it is important to understand clearly how it works by playing around the GUI and figuring out changes in output and the scripts created in the logs. This is a terrific way of understanding the Audit Command Language Scripts syntax. Try out this command and share your views in the comments.
