GENERAL COMMENT
In order to better understand and use the database, the quality or optimization of the database design must be sacrificed a little, giving more weight to its logical understanding.
The concepts of the WFD: Ecological status SW, Chemical status SW, Quantitative status GW, Chemical status GW should have a similar treatment in the database.
In this case the class QualityElement for SW EcoStatus should be equivalent to SWPrioritySubstance for SW ChemStatus.
In the case of GW the equivalent classes should be GWPollutant for GW chemical status and an equivalent class for GW quantitative status that doen't exist as the information related to quantitative satatus is directly stored in the class GroundWaterBody.
The design is not incorrect but really difficult to be undestood.
The reporting would be much easier to understand if the valid cycle EQS was stated and the base. Then an extra reporting element could have been some thing like "status according EQSD 2013" relevant only for the quality elements with altered eqs.
There is no distinction between the good status of an PS and the unknown status of an PS in a SWB. At this moment, the conclusion in the assessment reports is : when there is no reported failing for a PS in a SWB, the status for this PS is good in this SWB.
Please ad the option 'unknown'
It was rather difficult for us to report data for this class as different "concepts" had been included and had been combined. We would suggest to split it up (e.g. a separate class for reporting the effect of new EQSs on the status assessment) and include one class per "concept" that needs to be reported.
