LINQ to SQL和Entity Framework都是一種包含LINQ功能的對象關系映射技術。他們之間的本質區別在于EF對數據庫架構和我們查詢的類型實行了更好的解耦。使用EF,我們查詢的對象不再是完全對應數據庫架構的C#類,而是更高層的抽象:Entity Data Model。這為我們提供了額外的靈活性,但是在性能和簡單性上面也會有所損失。

The standard that governs the design of avioniccomponents and systems, DO-254, is one of the mostpoorly understood but widely applicable standardsin the avionic industry. While information on thegeneral aspects of the standard is easy to obtain, thedetails of exactly how to implement the standard aresketchy. And once an Entity develops a process thatachieves compliance, the details of how compliancewas achieved become part of the intellectualproperty of that Entity. This white paper focuses onthe details of developing a DO-254 compliantprocess for the design of FPGAs.
