使用Entity Framework将数据库从SQL Server切换到Oracle需要进行哪些更改？

Question

I have developed a MVC web application using Entity Framework with SQL Server as backend. I have used a database-first approach.

Now my client wants to switch to an Oracle database. I am in the process of doing impact analysis of switching from SQL Server to Oracle database. My client believes that it is as simple as changing connection string.

My question is, considering the fact that the table name, table structure, relationships and attributes are all same with SQL Server database, what changes do I need to do in my project to switch from MS SQL to Oracle?

Do I need to create a new edmx file for Oracle database or do I only need to change the connection string and use the same context?

Also if in future this needs to be reversed, then is there a good practice or solution to support both the databases?

Thank you.

Answer 1

oracle has a 30 character limit for item (table, index, column) so if you are verbose in any of your naming you are going to have to rename a bunch of items.

i don't like using an edmx. it might be easier with code first models.
