Power BI Publish to Web for Anonymous Access is Here

Earlier this week on Wednesday the Microsoft Power BI made an incredibly exciting announcement and released Power BI “publish to web” as a preview feature. This is HUUUUGE news! This was probably the top requested feature and its finally here thanks to the hard work and dedication of the Microsoft Power BI team!

Read Getting Started with R Visuals in Power BI

Power BI “publish to web” allows you to easily expose a Power BI report to the world through an iframe that can be embedded wherever you like.

To publish your Power BI report to the web, log into your Power BI site.

Find the report that you want to share and click File in the top left.
Power BI publish to web

You’ll see a message pop up box similar to below. Click the yellow button to create the embed code.

This is where you’ll see a very important warning!
WARNING: Reports that you expose through the “publish to web” feature will be visible to everyone on the internet! This means NO AUTHENTICATION is required to view the report that is embedded in your application.

Once you do that, you’ll receive an embed code that you can then use to expose your Power BI report within your blog as seen below!

As you can see the report maintains all the interactivity features of Power BI. And as your Power BI report updates and changes, those changes will be reflected in your embedded Power BI reports!

Pretty awesome!

MDX NON EMPTY KEYWORD VS NONEMPTY FUNCTION

Non Empty vs NonEmpty

Hey everyone, in this blog I want to address a very common MDX Question. What is the difference between the NON EMPTY keyword and NONEMPTY function? To take it a step further which one should you use?

Non Empty keyword VS NONEMPTY Function.

The big difference between the NON EMPTY keyword and the NONEMPTY function is when the evaluation occurs in the MDX. The NON EMPTY keyword is the last thing that is evaluated, in other words after all axes have been evaluated then the NON EMPTY keyword is executed to remove any empty space from the final result set. The NONEMPTY function is evaluated when the specific axis is evaluated.

Should I use NON EMPTY keyword or NONEMPTY function?

Ok Mitchell, so you told me when each of these are evaluated but really you haven’t told me anything up until this point. Can you tell me which one I should use already? Well, unfortunately, it depends. Let’s walk through an example of each using the BOTTOMCOUNT function.

BOTTOMCOUNT FUNCTION with NON EMPTY Keyword

In this example I’m returning the bottom ten selling products for internet sales. Notice that I have returned all products that have no internet sales, this is not necessarily a bad thing, maybe you want to return products that don’t have sales.

However if you don’t want to return these products then we can try using the NON EMPTY keyword. In the below example you can see the results when I add NON EMPTY to the ROWS axis.

WHOOOAAA, what happened?? A lot of people would have expected the results here to show the bottom ten products that DID have sales. However, that is not the case, remember that I said the NON EMPTY keyword is evaluated LAST after all axes have been evaluated. This means that first the bottom ten selling products which have $0 in sales are first returned and then the NON EMPTY keyword removes all that empty space from the final result.

BOTTOMCOUNT function with NONEMPTY function.

So let’s try this again, if you want to return the bottom ten products that had sales then we must first remove the empty space before using the BottomCount function. Take a look at the code below:

In this code we first remove the empty space before using the BOTTOMCOUNT function. The result is we return the bottom ten products that had internet sales. Once again neither one is right or wrong here it just depends on what you want in your final result.

NON EMPTY Keyword vs. NONEMPTY Function – Performance

There is a very common misconception that the NONEM

Why Query When You Can LINQ

Why Query When You Can LINQ

 

INTRODUCTION TO LINQ

LINQ is a abbreviation for Language Integrated Query, Which is just a fancy way of saying in that while in .net code you can write out your queries as if it were as simple as any other statement in you native programming language. For instance back it that distant past of 2006 a c# programmer would create a data table receiving object or some other in memory container. Then if up to standards create a data read and write object for the particular database, which would eventually have a query would be called with it filling the data table. But what if in memory objects, relational databases, and XML files could all be treated the same as OBJECTS! Objects such a magical word to us programmers, it could bring a tear. But it doesn’t stop there, there is in fact some performance gains to think over.

LINQ Performance

Of course the numbers vary based on circumstance and almost any bit of code can show slow performance if written incorrectly. With this in mind Uncompiled LINQ performance is will not wow anyone. It is in fact about 20% slower than traditional queries. But once compiled LINQ can show performance increases up to x6.0. Here is a great LINQ comparison with ADO.net.

Using LINQ

LINQ can integrate with a database in several ways. At heart LINQ is O/RM which means it would best work directly with the database, making each table an object. Each object can then be joined as needed and CRUD operations performed. Okay, I know you DBA’s out there are not to happy with that prospect! But LINQ also supports views and stored procedures. Here is a few examples.

[Table(Name="Products")]
public class Customer
{
            [Column(Id=true)]
            public string ProductID;

            [Column]
            public string ProductName;

[Column]
            public string Description;

[Column]
            public string Quantity;
}


V

Vola our object is created know lets use it.

DataContext db = new DataContext();

var q = from p in db.Products
            where p.ProductName == "DTS xChange"
            select p;
