Audit Command Language – Workspaces

Welcome to ‘Audit Command Language Tutorial for Beginners’ series. Most seasoned analytics professionals often complain that there are better tools that ACL to perform analytics on data sets. In most scenarios, this is a fair complaint against the ACL tool. However, if there is one feature that sets ACL apart from others is the ‘Workspace’. The ‘Workspaces’ in ACL are kind of a short cut to scripting when required to create the new fields. Simply define the required fields in the ‘Workspace’, select the table and activate the ‘Work Space’. You can then simply add the new columns via scripting or the GUI.

Creating a Workspace

Simply right click in the ‘Project Navigator’ on the left of the program. Select New -> Workspace and rename the new Workspace appropriately.

Scripting the Workspace

After creating the workspace, you need to write a script for the new column to be created in any existing table. Consider the sample script to create a new field ‘New_Gender’ from an existing field ‘Field_1’. The script in the work space would be

New_Gender                            Computed
alltrim(Field_1)

See below:

Activating the Workspace

Save the script in the workspace. Open the target table, right click on the workspace icon in the Project Navigator and click ‘Activate’. If you receive no pop-up, that implies the script in the workspace is correct and the new field is available to be added in the selected table. See image below

As you can see, the table ‘sample’ is selected the workspace is activated. Next, press ‘CTR + i’ to see the list of fields in the table. The newly created field would be present in that list.

To add a new column to the table using GUI, simply right-click on any column header in the table and select add column. Follow steps in the next windows and you’re done.

Going off the above example, imagine the possibilities of leveraging the same workspace to work on different tables. Essentially, the workspace is acting as complimentary scripts to the main scripts. It is for this reason, that in most script structures in ACL Audit Command Language, fields are not defined in the main body and certainly improves the performance of a project.
