Sometimes when I am working on a dynamic model for example, it is difficult to figure out which database value for a domain in the SF database translates to a particular translation in the GUI. For example, figuring out the database value in the table col for column 'calculated_field_type' when it is an expression or when it is a calculated column can be quite tedious. I usually then look for a column in the UI with the particular value I am looking for, and then query the database to find out what database value is associated with this.
What is the easiest way to figure this out? Is there a data dictionary somewhere I can refer to?
