DSE Version: 6.0
April 23, 2018

In this unit, we will be moving on to the counters data type. A counter is a data type where you can store a 64-bit signed integer that can be incremented or decremented. These could be useful, depending on your data model.

DSE Version: 6.0
April 23, 2018

In this unit you will be learning about UDTs, or User Defined Types. These are useful if you need to store a more complex data structure wihin a single cell in your table.

DSE Version: 6.0

In this unit, yhou will be learning about the collections data types. Collections allow you to store multiple values in each cell, while still keeping the values in dividuality.

DSE Version: 6.0
April 23, 2018

There is some other neat CQL functionality that you should be familar with before you get down to creating your data model. This includes collection data types, UDTs, counters, UDFs and UDAs.

DSE Version: 6.0
April 23, 2018

In this unit, we will be covering denormalization, and how to denormalize for an Apache Cassandra data model.

DSE Version: 6.0
April 23, 2018

The other half of the primary key (besides partition keys) is called clustering columns. You combine the two to make a stellar data model. Learn about clustering columns in this unit. 

DSE Version: 6.0
April 23, 2018

We will be talking about partitioning and storage structure in this unit, both very important topics for Apache Cassandra data modeling.

DSE Version: 6.0
April 23, 2018

In this unit, you will be learning about the fundamentals of an Apache Cassandra table. There is a lot of terminology you need to learn here, which is especially important for data modeling. But we will break it down and guide you through it.

DSE Version: 6.0
April 23, 2018

In this unit, you will learn just enough Cassandra Query Language, or CQL, to be dangerous. You will need this to create physical data models in Apache Cassandra.

DSE Version: 6.0
April 23, 2018

To learn about Apache Cassandra data modeling, we will be using a movie domain for a sample application called KillrVideo. This unit will introduce you to the KillrVideo application.
