Now that we have implemented a working data model in Apache Cassandra or DataStax Enterprise, it is time to make sure that the data model works properly and performs the way we want it to. In this unit, you will learn about analysis and validation of your data model.

How do we migrate our existing data model into a new one when using DataStax Enterprise? In this unit, we will explore different way that it can be done, and go through some important points to keep in mind while doing so.

In this unit, you will learn about table/key optimizations. Most likely the majority of the optimizations we can make to our data model involve making changes to our table's schema, particular to the primary key.

In this unit, we will be taking a look at some alternate ways to perform reads in Apache Cassandra or DataStax Enterprise. For example, in some cases using an index may be helpful. Or if certain requirements or queries change, it may be possible to enable these changes without completely overhauling your data model.

Using Apache Cassandra at the core of DataStax Enterprise, write operations are designed to be as efficient as possible. But there are some techniques that can be used in terms of data modelling for dealing with specific challenges. We discuss this further in this unit, with a focus on batches and lightweight transactions.
