TableToken buildingtypeToken = schemaBuilder.Create(buildingTypeDescription);
// Creating a 'Building' feature class with three fields - BuildingId, Address, and BuildingType
FieldDescription buildingId = FieldDescription.CreateIntegerField("BuildingId");
FieldDescription buildingAddress = FieldDescription.CreateStringField("Address", 100);
FeatureClassDescription featureClassDescription = new FeatureClassDescription("Building", new List<FieldDescription> { buildingId, buildingAddress, buildingType }, new ShapeDescription(GeometryType.Polygon, SpatialReferences.WGS84));
FeatureClassToken buildingToken = schemaBuilder.Create(featureClassDescription);
// Creating M:M relationship between the 'Building' feature class and 'BuildingType' table
AttributedRelationshipClassDescription attributedRelationshipClassDescription = new AttributedRelationshipClassDescription("BuildingToBuildingType", new FeatureClassDescription(buildingToken),
new TableDescription(buildingtypeToken), RelationshipCardinality.ManyToMany, "OBJECTID", "BuildingID", "OBJECTID", "BuildingTypeID");
// Adding optional attribute field in the intermediate table - 'OwnershipPercentage' field
attributedRelationshipClassDescription.FieldDescriptions.Add(FieldDescription.CreateIntegerField("OwnershipPercentage"));
