User Defined Functions and User Defined Aggregates are a little bit complex. We tend to use these in conjunction with one another to get the functionality we need in our table. Learn more about UDFs and UDAs in this unit.

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.

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
April 23, 2018

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

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 part 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

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.
