Before publishing the database, there are lot of things must be done to help your client understand the database tables and fields in a better way. Out of many, captioning each table’s field helps your audience understand the reason of defining of fields, data type to be used, and any hidden applied constraints.
For client convenience, you can caption table’s column. To caption one, open the table and head over to Fields tab and click Name & Caption.
A dialog will pop-up, letting you caption the column label.
