## Running a data quality check

A data quality check checks the whole of the current HelicsWin.Net database.

To run a data quality check:

1. Click Data quality check in the main menu.

The Data quality check form opens.

2. In the Messages level field, select Warnings and errors (recommended).

3. Deselect Enable output updating during the check (recommended).

Enabling this option updates the data displayed in the Data quality check output field every time a new line is added. If this option is not enabled, updates are only made periodically.

If the output consists of only 50 lines, for example, you can evaluate the output displayed in the Data quality check output field. However, if you have verbose output (Message level = all) and you have many patients, etc., thousands of lines of output might be displayed in the field. In such a case, if you enable this option (i.e. if you check this check-box), system response time can be very slow; whereas leaving this option unchecked will improve system speed.

4. Click Check data.

When the processing has finished, the resulting messages are displayed in the data quality check output text box, and the (colour-coded) breakdown of the Error, Warning, and Success counts are shown underneath.
