1. Entity Framework from a database perspective
Mattias Lind, MCT & MVP Data Platform

2. First session
I know it’s really early on a Saturday morning, but the great thing is that we have a full day ahead. If it’s been a Sunday morning, the logo in the bottom, right corner would have been wrong. It’s really awesome to have SQL Saturday today, and I’m looking forward to this. Did you know there’s another SQL Saturday today as well, in Johannesburg, South Africa. Anyway, I’m really happy being here and I hope you are excited about all the good content we have here today. I have already planned for what sessions I’m heading to after this session. So I guess we should get started. Have you been reading this slide? This slide is intentionally not left blank. If you have been reading this far, please giggle a bit. If you hear someone giggle before you, giggle harder. When all of you are laughing I’m changing the slide. If you still not laughing you probably think this slide is silly, and it is!

3. Without Our sponsors we wouldn’t be here!

4. Thank you Sponsors!

Agenda
Entity Framework
Database Design
Demo
Sogeti * 2014
MVP * 2011
MCT * 2001
SQL * 1995
IT * 1992
BASIC * 1982
Birth * 1972

6. Entity Framework ORM for .Net Entities, Attributes, Relationships
Currently 6.1.3
EF Core
Complete rebuild
Still beta (I hope so anyways...)
Huge backlog
Looks promising
Library Package Manager Console
Install-Package EntityFramework

7. Entity Framework
Two layers
Model
Object

8. Entity Framework The Model Layer Conceptual Logical Model
Physical Database Schema
Mapping between Logical and Physical

9. Entity Framework The Object Layer
Run queries against the conceptual model.
Materialize data as objects.
Track changes to the objects.
Propagate changes to the data source.
Bind objects to controls.

10. Entity Framework
Methodology
Database First
Model First
Code First

11. Reality check! Developers tend to like Code First
DBAs tend to like Database First
Architects tend to like Model First

12. Just a small commercial break!
Give the sponsors an applause!

13. Demo MVC ASP.Net with C# in VS2015 Code First
Add data types and procedures

14. SQL Server Relational Database Management System Latest version 2016
Awesome features
In-Memory OLTP

15. Physical Database Data file Filegroup Log file Rows Pages Extents
Transactions
Checkpoints

16. Logical Objects Database Schema Table Index View Function Procedure
Trigger

17. Database Modelling/Design
Logical/Physical model
Normalization/Generalization/Denormalization
Symmetric/Predictable
Performance enabling
Security enhancing

18. In-Memory OLTP Introduced in SQL Server 2014 Enterprise
Row store, no pages
Persisting/Non-persisting
Based on FileStream
No locking/Versioning
Indexes only in RAM
Fast, faster, fastest
Natively compiled
Transparent, (almost) no change in code

19. Common Sense
Need
Future
Benefits
Challenges

20. Demo MVC ASP.Net with C# in VS2015 Code First
Add data types and procedures
Remodel the database
To disk based tables
To In-Memory OLTP with natively stored procedures (If time permits we can do this live!)

21. Conclusion Entity Framework adds possibilities
A full abstraction layer should also consist of supporting database objects
Procedures, views and functions are still cool
In-Memory OLTP can add extreme performance possibilities
Use common sense
