Critically evaluate the Design and Implementation in relation to the object orientated principles covered in the module. You must consider the patterns you have used and discuss if they were effective and also identify any patterns you have not implemented but believe to be relevant. Discuss the choice of Data Access implementation. Was Entity Framework directly used or did you impose your own unit of work and repository patterns. You need to justify and reflect on the choice you made. Critically evaluate your application in terms of security. You should focus on the security needs of the application from the data perspective, password security may be discussed but it should not be the main part of this evaluation.
