Draw me an ERD based on this information$-$ Entities:

AdverseEvents:

Attributes: AdverseEventID $($PK$),$ PatientID $($FK$),$ MedicationID $($FK$),$ EventDescription, Timestamp.

Medications:

Attributes: MedicationID $($PK$),$ MedicationName, MedicationClass, DosageForm.

Patients:

Attributes: PatientID $($PK$),$ Age, Sex, Race, ResidenceCity, ResidenceState.

Outcomes:

Attributes: OutcomeID $($PK$),$ AdverseEventID $($FK$),$ OutcomeDescription, RecoveryTime.

UsagePatterns:

Attributes: UsagePatternID $($PK$),$ MedicationID $($FK$),$ PatientID $($FK$),$ Dosage, Frequency, StartDate, EndDate.

Relationships:

AdverseEvents $-$ Medications Relationship:

Many$-$to$-$One relationship between AdverseEvents and Medications via MedicationID.

An AdverseEvent can be linked to one Medication, but a Medication may be associated with multiple AdverseEvents.

AdverseEvents $-$ Patients Relationship:

Many$-$to$-$One relationship between AdverseEvents and Patients via PatientID.

Multiple AdverseEvents can be linked to one Patient, but a Patient may be associated with multiple AdverseEvents.

AdverseEvents $-$ Outcomes Relationship:

One$-$to$-$One relationship between AdverseEvents and Outcomes via AdverseEventID.

Each AdverseEvent has one corresponding Outcome, and an Outcome is linked to a specific AdverseEvent.

Medications $-$ UsagePatterns Relationship:

One$-$to$-$Many relationship between Medications and UsagePatterns via MedicationID.

A Medication can have multiple UsagePatterns, but a UsagePattern is linked to a single Medication.

Patients $-$ UsagePatterns Relationship:

One$-$to$-$Many relationship between Patients and UsagePatterns via PatientID.

A Patient can have multiple UsagePatterns, but a UsagePattern is linked to a single Patient.

Key Attributes:

Primary Keys: AdverseEventID, MedicationID, PatientID, OutcomeID, UsagePatternID.

Foreign Keys: PatientID $($in AdverseEvents, UsagePatterns$),$ MedicationID $($in AdverseEvents, UsagePatterns$),$ AdverseEventID $($in Outcomes$).$
