I can teach you Snowflake analytics!  Today we are going to learn about Cume_Dist. Cume_Dist returns the cumulative distribution of a value within a set of values. It represents the number of rows with values less than or equal to that row’s value divided by the total number of rows. The returned value of the CUME_DIST function is greater than zero and less than or equal one.

I can teach you Snowflake analytics!  Today we are going to learn about Ntile. Each Ntile partition is assigned a number starting at one increasing to a value that is up to the Ntile partition number specified.  So, with a Ntile of 4, the partitions are 1 through 4.  Then, all the rows are distributed as evenly as possible into each partition from highest to lowest values.  Normally, extra rows with the lowest value begin back in the lowest numbered partitions.

Some major companies use the listagg analytic for their email marketing campaigns.  They cleverly find out the last three web pages the customer went to on their website, and then they send them a customized email offering sales on the products they were viewing last.

I can teach you Snowflake analytics!  I have never seen a database do analytics better than Snowflake.  Last week we taught you Lead, and this week we are teaching you Lag. You use a Lead to place the value from the next row on the current line of the answer set.  You can then see today’s value, and on the same line, see tomorrow’s value.  You do the opposite for the Lag.  You can see today’s value, and on the same line, see yesterday’s value.

I can teach you analytics!  I have never seen a database do analytics better than Snowflake.  This week we are working on the Moving Difference, which is interchangeable with MDIFF.

I can teach you analytics!  I have never seen a database do analytics better than Snowflake.  This week we are working on the Moving Average, which is interchangeable with the word MAVG. You use a Moving Average (MAVG) to look for trends.  A MAVG shows you the AVG of values in a moving window, which means a certain amount of rows.  If the moving window is a three, then the MAVG calculates the AVG for the values for three rows.  You can then see trends by analyzing which results were higher and which were lower.

We are proud to offer Universal ODBC – our new connection method that allows users to connect to and interact with any current or future ODBC data source in the universe.  

Nexus has always been able to interact with over 25 major data sources natively, but not brand-new data sources.  With Universal ODBC, users can now connect to any data source, display the database layout in our Unified Systems Tree, execute SQL, and interact with result sets in exactly the same way they can from any of our native connection methods.  All that is needed is an ODBC driver.

There are so many new and exciting databases emerging daily, but until now, users have had limits to using the simple vendor-supplied “afterthought” query tools designed specifically for those systems. Nexus Universal ODBC allows users to query new cloud or on-premises databases on the day they’re released.

Moving data between systems is called ETL, which stands for Extract, Transform, and Load.  The ETL team almost always does the moving of data because load scripts are easier to learn than Latin, transformation is more difficult than brain surgery, and computing resources are about as easy to manage as cats.
