Name: Section: Question 1: Data Normalization (60 points) A local environmental regulatory agency collects data on leaking underground storage tanks. The agency currently maintains the data in the following table: Table: SAMPLING DATA Primary Key: UTNumber+MWNumber+ SamplingDate+Contaminant Attributes: AcceptableLevel AnalyticalPOC AquiferThickness City Concentration ContactPerson Contaminant DateofPermitIssue Depthto Water DrivingContaminant FacilityID FacilityName GroundwaterFlowDirection HydraulisConductivity HydraulicGradient InitialContaminantMass Methodused MWNumber MWCoordinates MWDepth MWDiameter MWNumber Performdeby Phone Sampling Date SamplingMethods StreetAddress Transmissivity TypeofTreatment UTNumber ZIP In addition to the functional dependencies implied by the primary key, the following functional dependencies have been identified. Contaminant AcceptableLevel FacilityIDFacilityName FacilityID -StreetAddress FacilitylD ->City FacilitylID State FacilityID - > ZIP FacilityID-Phone FacilityID- ContactPerson UTNumber Facility!)

Ensure that it is a lossless-join decomposition. Give each table an appropriate name. Specify the attributes in the tables and identify the primary keys Specify the forcign key relationships
