FinancialBroker - MDI application with EF code first database.
1.Database.
In this page I describe start of one my interesting project. This project is huge, and this is only a start. First point is database. This is my first project I try to use EF Code First technology with deploy and migration to MS SQL server. In this project I use relation M:1. 1:M, 1:1 and M:M Визначення зв'язків даних 1:1, 1:M, M:M у базі та EF CodeFirst..
I try to describe CRUD pattern around one entity of this project - Person.
This is main class of definition Person.
