The document discusses leveraging .NET development for SQL Server developers. It summarizes a presentation given by Marco Parenzan on developing a CRM application using .NET instead of only SQL. The presentation discusses using Entity Framework, ASP.NET MVC, web services and other .NET technologies to access and manage data in SQL Server. It provides examples of how a SQL Server developer could develop applications by consuming SQL Server and data via .NET libraries, web applications and other methods instead of only using T-SQL. The presentation encourages SQL Server developers to explore opportunities in .NET to develop applications more fully instead of just focusing on SQL Server.

7. .NET State of the Art
Mature environment
2002+
8 versions
Consistent
(Server side) pervasive
environment
Devices, Web
(HTML5/CSS3/Javascript) are
here to stay
Possibility of a scale-out model
Data services
ASP.NET .NET/WCF

8. C# State of the Art
Mature and powerful and expressive language
Declarative approach is in general correct
But it’s not (always) confortable
Imperative language
Tell how to do it…
…not just what you want...
…sometimes is faster…
Many functional/SQL goodies
LINQ
Many scalability goodies
Parallelism
Async
Start talking about «cost of manteinance»
Not performances

12. A story from a SQLServer
Developer
Dicembre 13th, 2013
#sqlsat264

13. The story is about a CRM
Among many others
Just change CRM with *  (it’s the same)
The story is about a boy…
…that is SQL-based (a BI guy!)
…that tries to solve all things with SQL
Sometimes (I think) he does things
«complicated»
could be «declarative vs. imperative»
programming
But this is another story

14. Create a DB in a Developer way
Remembering #sqlsat176
http://www.slideshare.net/marco.parenzan/sql-server-data-tools15242283
Remembering Gian Maria Ricci’s session

“Database projects strikes back”
As a project inside Visual Studio
SQL Server Data Tools
A «restart» for Database Project…
Model based
Differential Updates
All aspects for SQL Server Database developments
Not administration
Just Model
Also SQL CLR

15. A story from a SQLServer Developer:
needs
I need to
do it «@
home» 
I need to
import
data
I need to
admin
data
I need to
handle
data
I need to
share the
data
Dicembre 13th, 2013
Start here
I need to
edit data
The only thing I can’t do (?)

#sqlsat264

18. SQL Server Access by System.Data
Connected Way
The faster way
Magic strings
Write SQL!
Tables/Views/Stored Procedures
From the beginning (2002)…
…here to stay!
Dicembre 13th, 2013
#sqlsat264

19. SQL Server Access from other data
Excel Workbooks, Xml, Json
Just Import Data?
Libraries libraries libraries
For exampleASPOSE.Cells
Complete implementation of a Excel object model
No dependencies from Office
Good for Server Side scenarios
And other office tools are the same

20. Pros & Cons
Pros
Rich data manipulation
Speed of coding (imperative way)
Cons
Speed of execution

21. SQL Server by Entity Framework 6.0
Programmers love objects
Impedance Mismatch (Davide…where are you?)
EF 6.0
A step forward
Finally, Create/Update/Delete methods mappable on
SP!
And we can work with ViewModels
A modern approach to applications
No more «one model for all»
Dicembre 13th, 2013
#sqlsat264

22. Pros & Cons
Pros
Modeling in a more intuitive way
Recover speed of execution with store procs
Cons
Impedance Mismatch (analisys more
importat)

23. Web Apps with ASP.NET MVC 5.0
Scaffolding! Scaffolding! Scaffolding!
Scaffolding! Scaffolding! Scaffolding!
Here I can say it!
It’s not a good pattern for Enterprise-grade
applications…
…but sometime is useful
No, I’m not speaking about Javascript, just
HTML5 (and CSS3)
Your apps will be «nice» 

24. Expose Data as Data Services
JSON is here to stay
Web Services are REST
XML is just a Server to Server Scenario
BI and Cloud models loves it!
Dicembre 13th, 2013
#sqlsat264

25. Pros & Cons
Pros
Powerful way to express data
More control over execution
Json and Xml
Cons
Impedance Mismatch (analisys more
importat)

26. Consume Data and SQL Server via Powershell
Powershell is the new Command Line
How many times did you hear it?
Don’t be lazy (me too!)
Expressive
Verbs-Noun
Objects  Metadata
Pipelining (functional)
Rich imperative language
Powershell is entirely .NET
Extendable with .NET: CmdLets
Dicembre 13th, 2013
#sqlsat264

27. Consume Data and SQL Server with Libraries
Why reports only with Reporting Services?
Why not a…
…word document
…excel workbook with graph and pivot
…a Powerpoint presentation
…a Visio Graph?
…Bar codes?
Manupulate data for presentation
ASPOSE…again
I don’t sell ASPOSE…
…but I love it!
Again: it’s just one of many

28. Consume .NET inside SQL Server
Host C# (CLR) code inside SQL Server
Stored Procedures
UDT
Access to «all» .NET libraries
Just a little bit of dependencies
UNSAFE
It’s not a real issue
Just create another DB

29. Two other stories
from a Developer POV
Dicembre 13th, 2013
#sqlsat264

30. The Cloud is here to stay!
Windows Azure is a real opportunity for the
.NET Developer
I think for ALL developers
This year:
Scott Guthrie and Mark Russinovick in Azure Team
A lot of updates this year! Developer friendly!
Dicembre 13th, 2013
#sqlsat264

31. The tools are no more where to start
.NET or C# or ASP.NET are not where to start
They are not a pillar or a constraint
It’s the consequence of an analysis (what we can
call «bounded context» in Domain Driven Design –
the right choice is for each context)
Is the same for SQL Server developer?
I think so
ALM is important
Dicembre 13th, 2013
#sqlsat264

32. ALM is important
Analysis
SCRUM
Team Foundation Server
See Alessandro Alpi «Put database under
source control» session!

33. CONCLUSION
Dicembre 13th, 2013
#sqlsat264

34. There were three guys in front of a
pizza…
…last month!
Live confortable with SQL Server…
…but don’t look just inside your garden!
If you don’t believe me, just try by yourself:
I’m not saying use .NET….
…I’m saying «there is .NET»
Technology is good because you can fall in
love more times…
...at the same time!
