As far as I can tell, this SQL should enforce these constraints naturally. The ModelScore has a particular "meaning," which is contained in the Definition. Nothing earth-shattering there. Now, I try translating this into Entity Framework using the designer. After updating the model from the database and doing some editing, I have a Person object, a Model object, and a ModelScore object. PersonModelScore, being a join table, is not an object but rather is included as an association with some other name (let's say ModelScorePersonAssociation). The mapping detail

Each Product can be assigned any or all of the Customer's Payment Methods, with one set as default. Foreign Keys are: Customer.CustomerId => Product.CustomerId Customer.CustomerId => PaymentMethod.CustomerId Product.ProductId => ProductPaymentMethod.ProductId PaymentMethod.PaymentMethodId => ProductPaymentMethod.PaymentMethodId I want to customise this model for presentation purposes, Customer to have a collection of Payment Methods and a collection of Products. Products to have a collection of ProductPaymentMethods which inherit from PaymentMethod. I deleted the association between PaymentMethod and ProductPaymentMethod, added an inheritence from PaymentMethod to ProductPaymentMethod and deleted PaymentMethodId from ProductPaymentMethod. This is now my model: When I save the model or build the project I get 2 errors: Error 3002: Problem in mapping fragments starting at line 226:Potential runtime violation of table ProductPaymentMethod's keys (ProductPaymentMethod.ProductPaymentMethodId): Columns (ProductPaymentMethod.ProductPaymentMethodId) are mapped to EntitySet PaymentMethods's properties (PaymentMethods.ProductPaymentMethodId) on the conceptual side but they do not form the EntitySet's key properties (PaymentMethods.PaymentMethodId). and

I suppose it is common, and in fact I think I recall reading posts on Usenet about this, without many solutions. The problem comes when you have a mapping from one table to another. The error in this case comes in the form of two errors during compile: Error 3002: Problem in Mapping Fragment starting at line 498: Potential runtime violation of table QuotePricedLineItem's keys (QuotePricedLineItem.ObjectId): Columns (QuotePricedLineItem.ObjectId) are mapped to EntitySet FK_QuoteLineItem_QuoteVendorLineSet's properties (FK_QuoteLineItem_QuoteVendorLineSet.QuoteVendorLineSet.ObjectId) on the conceptual side but they do not form the EntitySet's key properties (FK_QuoteLineItem_QuoteVendorLineSet.QuotePricedLineItem.ObjectId, FK_QuoteLineItem_QuoteVendorLineSet.QuoteVendorLineSet.ObjectId). Error 3003: Problem in Mapping Fragment starting at line 498: At least one of the key properties of AssociationSet FK_QuoteLineItem_QuoteVendorLineSet must be mapped to all the key properties (QuotePricedLineItem.ObjectId) of table QuotePricedLineItem
add another entity that is related in the database to the first entity, Visual Studio will give you a "Problem in Mapping Fragments" error. For example, if you add a Northwind database Orders table using the EDM Update Wizard, it produces an entity that looks has an EmployeeID property that corresponds to the EmployeeID foreign key column of the Orders table. Next, if you add a Northwind database Employees table using the EDM Update Wizard, an Employees property gets added to the bottom of the Orders entity under Navigation Properties and a relationship between the Orders and Employees entities is shown on the diagram. However, there is still an EmployeeID property on the Orders entity. This is what causes the "Problem in Mapping Fragments" error. In order to get around this error, you can simply remove the redundant EmployeeID property from the Orders entity by right-clicking it in the designer and selecting Delete from the shortcut menu.
