Data Points: Designing an Entity Data Model


With the Entity Framework, developers are given more flexibility by being able to design around a conceptual model rather than a relational data model. To get started, you need to know how to design an Entity Data Model. John Papa walks you through that process.

Entity Data Model and database view returning the same columns as there are in a table


When adding a stored procedure into the Entity Data Model I can select whether the procedure returns a scalar, a (new) complex type or one of the entity types I already defined. 

How do I do something similar for a view?

I mean assuming I have a view like this

CREATE VIEW FilteredFoos as SELECT Foo.* FROM Foo join ... WHERE ...

(that is a view that implements some involved filtering, but returns all columns from one table) how do I add it to the project so that I can use the entity set, but get the Foo objects, not some new FilteredFoo objects.

var foos = myDB.FilteredFoos.Include("Bar").ToList();

foreach (Foo foo in foos) { ...

Thanks, Jenda

Optimizing Data Mining processing time for a Time Series model in SQL Server 2008 R2


Does anyone have any references around optimizing the initial processing time for a data mining model? Books, blogs, etc. I have the Wiley “Data Mining with SQL Server 2008” book, and while I’ve learned a lot from it, it doesn’t seem to cover much around trouble shooting things like processing time. I also have a few other books that have a chapter or two on data mining, but again just basic “here’s what it is and how to set it up”, nothing that quite covers trouble shooting or optimization. I’ve also checked out the various Data Mining blogs/sites.


I’ve got a Microsoft Time Series model I’m basing on a Cube. Very simple, trying to forecast sales. I have one dimension which is the list of products (about 1600), a second which is the time dimension, finally the measure is daily sales figures for each, about 3.2 million rows in total. On a brand new server, with two quad core processors and 16 gig of ram it took 40 hours to process. Seems rather high?

How to update Domain Service from Entity Data Model?


Hi guys,

So I'm using Entity data model to reflect my database and I generate Domain service from my Entity data model.

I understand that if I have changes in my database, I can just choose "Update Model from Database", but there is no "Update Domain service from Model" option available.

How should maintain my domain service? I'm not going to delete away it and regenerate it whenever there are some changes, right?

I need to know what if

- I add in new table in my database, how should I update from database-->model-->domain service?

- I add in new fields in my table, how should I update from database-->model-->domain service?


Problem with SQL server 2008 UDF and model data entities


Hi everyone. I'm very new with this technology and still have to learn lot's of stuff...

I managed to start with basic MVC design but i'm now stuck on adding functions to model..

I created view in mssql

SELECT table1.Field1, table2.Field2
FROM table1 INNER JOIN table2 ON table1.Field1 = table2.Field1

and function

CREATE FUNCTION fnGetMyViewResult(@paramField nvarchar)
RETURN SELECT * FROM MyFirstView WHERE MyFirsView.Field1 = @paramField

but when i run entity data model wizzard from VS 2010 i can chose only from tables, views and stored procedures. There is no way (atleast no way i know about) to add my sql function to MVC model...

I can see function in ServerExplorer but not in wizzard....

Can someone help me with this?

Thanks in advance..

Populate entity data model from database


I've been using entity data models for quite a few sections of my website and find it really good for saving things to the database.

After searching for a while, I can't seem to find a good way to populate a new instance with data from a database other than using a data reader. E.G:

MyClass.myID = reader("myID")

Am I missing something?

Dynamic Data using Code First Entity Framework Model


I have used Dynamic Data before using LinqToEntity where my Entity model used the Data First model and the GUI.  Now I am trying to use the Code First model witht he Entity CTP 4.  I have my model created and created a new Dynamic Data site.  I read that I need to replace the default RegisterContext call:

DefaultModel.RegisterContext(typeof(PriceLoaderContext), new ContextConfiguration() { ScaffoldAllTables = true });


DefaultModel.RegisterContext(new DomainModelProvider(typeof(PriceLoaderContext)), new ContextConfiguration() { ScaffoldAllTables = true }); 

When I search further on DomainModelProvider, I find that it is part of the WCF RIA. Is this correct? Is this what I need for this to work? Has anyone else done this and got it to work?


Differences between SQL Server database definition and dynamyc data .edmx model


I am trying to customize a ForeignKey_Edit under a different name but I am having a problem with this: If I am listing one of the entities I have 4 columns that appear as links. My guess is that they are the Foreign Keys because they are the same fields listed as DropDownLists on top of the page.

One of this fields is the one I am trying to customize but if I use the UIHint attribute or property I got an error message saying that the columns can't be used as a Foreign Key because it isn't  a Foreign Key, but it is.

I have checked the database definition and in it the column appears as Foreign Key but in the Dynamic Data .edmx model appears as a simple field because it doesn't show the small key on the left icon. Only primary keys have the key.

Is this a bug or am I going the wrong direction?
