In this unit, you will learn how to map your conceptual data model to a logical one, also using the access patterns from your application workflow. 

DSE Version: 6.0

We need to figure out how users are going to navigate through our application. We call this the application workflow. This is necessary so we know which queries to perform against our Apache Cassandra database. Learn more about the application workflow in this unit.

Conceptual data modeling is essentially taking all the objects in your domain, determining their attributes and seeing how all of them are related together. In this unit, you will learn about conceptual data modeling with Apache Cassandra.

DSE Version: 6.0
April 23, 2018

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.

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
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.

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 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.
