WRDB has powerful organizational capabilities that encourage you to perform proper QA/QC on your data. As discussed in Working and Master Table Overview, you must validate each and every record in a Working table before it is a candidate for elevation to Master table status. Data validation would typically be done by experienced water resources or environmental engineers and consist of a review of data for reasonableness and consistency. WRDB keeps track of those who enter, validate, and transfer data to and from each Working table (see, for example, the discussion for creating new Working tables).
When you use this command, WRDB reports how many of the currently selected records in the current Working table are marked as unvalidated, and asks you to confirm the operation. After changing the Validated flag for all records, you are presented the Journal Entry form (unless the Project Preferences are set to suppress this).
