Good morning Data science enthusiasts...

Have you heard of a new DBMS(DataBase Management System) that is developed with the features of our ancestral SQL and NoSQL database..???

Not sure what we are talking about... Let's have a look at this new technology...

Good morning friends...

The biggest & most unavoidable issue that we face with our datasets is of missing data.

It might seems to be a easy term but let's have a look at it in depth.

Hello friends...

Hope we have studied about the theory of Partitioning and Bucketing in Hive..

Time to get our hands dirty and learn how we can write code for the same and see the difference...

Hello Data scientists...

In our recent articles we learnt about the Missing Data... But how should we deal with it.. how should we handle them..!!!

So, this process of handling missing data is known as IMPUTATION...

So, let's learn about Imputation and its techniques...

Hello Data scientists...

Another important thing in regard to data science is how well are able to read and understand the data. Not only this it also depends on how good we were able to present the data to others, so that we are able to get the maximum insights from it...

It is indeed a tedious task to visualise the data. So, we would like to present you with a technique that can help in visualzing and analysing the data in a single click.

Hello friends...

A very talked topic when we talk about Hive is type of tables.
This is also an important interview questions and acts as a decider for your further interview direction.

So let's see what are the different types of tables in hive and the difference between them..

Hello friends...

We read about the outliers in our previous posts... But what about handling them.!!!

So, we would like to present you a technique popularly known as "capping/censoring/winsorizing" .

Hii...

We studied about Partitioning in Hive... But have we ever thought what would happen if the Partitioning column is NULL.?

No..!!

Don't worry.... We have got you an article on how to handle NULL values in partitioning column.
