Apache Cassandra

April 23, 2018

Now lets get down to creating table in Apache Cassandra! That's what this unit is all about. This is how we create our physical data model.

Logical Data Modeling

April 23, 2018

Now let's get into the details of creating a logical data model. In this unit, we go through some rules to consider when putting together your logical data model.

Mapping Conceptual To Logical Model

April 23, 2018

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.

Application Workflow And Access Patterns

April 23, 2018

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...

Conceptual Data Modeling

April 23, 2018

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.

UDFs And UDAs

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.

Counters

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.

UDTs

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.

Collections

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.

Table Features

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.
