It's just so rewatchable and so memorable and it was the first time I've seen a Mario video on the internet that takes the Mario franchise and makes it something completely different from what they officially are.
Also the music used throughout this series is badass I love Tekken 5 so that's probably another reason why I love this so much.
I have always been a big fan of sprite movies, and this one is no exception. I used to watch this a lot when I was younger!
Seeing Mario go on a rampage while being controlled by Boos always filled me with dread! I remember watching these in like and was still late to the party.
I was simply too young to discover and enjoy NG that far back. Good animations, voice acting, and music. Power Star Share Collapse.

No matter what you choose to do now that Star Power has ended, Garth and Michael will always be grateful for your love and support. This article targets Power BI Desktop data modelers.
It describes star schema design and its relevance to developing Power BI data models optimized for performance and usability. This article isn't intended to provide a complete discussion on star schema design.
Star schema is a mature modeling approach widely adopted by relational data warehouses. It requires modelers to classify their model tables as either dimension or fact.
Dimension tables describe business entities—the things you model. Entities can include products, people, places, and concepts including time itself.
The most consistent table you'll find in a star schema is a date dimension table. A dimension table contains a key column or columns that acts as a unique identifier, and descriptive columns.
Fact tables store observations or events, and can be sales orders, stock balances, exchange rates, temperatures, etc.
A fact table contains dimension key columns that relate to dimension tables, and numeric measure columns. The dimension key columns determine the dimensionality of a fact table, while the dimension key values determine the granularity of a fact table.
For example, consider a fact table designed to store sale targets that has two dimension key columns Date and ProductKey.
It's easy to understand that the table has two dimensions. The granularity, however, can't be determined without considering the dimension key values.
In this example, consider that the values stored in the Date column are the first day of each month. In this case, the granularity is at month-product level.
Generally, dimension tables contain a relatively small number of rows. Fact tables, on the other hand, can contain a very large number of rows and continue to grow over time.
Star schema design and many related concepts introduced in this article are highly relevant to developing Power BI models that are optimized for performance and usability.
These queries are used to filter, group, and summarize model data. A well-designed model, then, is one that provides tables for filtering and grouping, and tables for summarizing.
This design fits well with star schema principles:. There's no table property that modelers set to configure the table type as dimension or fact. It's in fact determined by the model relationships.
A model relationship establishes a filter propagation path between two tables, and it's the Cardinality property of the relationship that determines the table type.
A common relationship cardinality is one-to-many or its inverse many-to-one. The "one" side is always a dimension-type table while the "many" side is always a fact-type table.
A well-structured model design should include tables that are either dimension-type tables or fact-type tables.
Avoid mixing the two types together for a single table. We also recommend that you should strive to deliver the right number of tables with the right relationships in place.
It's also important that fact-type tables always load data at a consistent grain. Lastly, it's important to understand that optimal model design is part science and part art.
Sometimes you can break with good guidance when it makes sense to do so. There are many additional concepts related to star schema design that can be applied to a Power BI model.
These concepts include:. In star schema design, a measure is a fact table column that stores values to be summarized. In a Power BI model, a measure has a different—but similar—definition.
It's important to understand that Power BI models support a second method for achieving summarization. These columns are referred to as implicit measures.
They offer a convenience for you as a model developer, as in many instances you do not need to create measures. For example, the Adventure Works reseller sales Sales Amount column could be summarized in numerous ways sum, count, average, median, min, max, etc.
However, there are three compelling reasons for you to create measures, even for simple column-level summarizations:.
However, Power BI Desktop live connections allow report authors to show hidden fields in the Fields pane, which can result in circumventing this design approach.
A surrogate key is a unique identifier that you add to a table to support star schema modeling. By definition, it's not defined or stored in the source data.
Commonly, surrogate keys are added to relational data warehouse dimension tables to provide a unique identifier for each dimension table row.
Power BI model relationships are based on a single unique column in one table, which propagates filters to a single column in a different table.
When a dimension-type table in your model doesn't include a single unique column, you must add a unique identifier to become the "one" side of a relationship.
