LINQ to SQL和Entity Framework都是一种包含LINQ功能的对象关系映射技术。他们之间的本质区别在于EF对数据库架构和我们查询的类型实行了更好的解耦。使用EF,我们查询的对象不再是完全对应数据库架构的C#类,而是更高层的抽象:Entity Data Model。这为我们提供了额外的灵活性,但是在性能和简单性上面也会有所损失。

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.
