Hello and welcome to the final lecture, where I’ll briefly summarize some of the core points I mentioned in the course. 

In this course, we discussed the fundamentals of DynamoDB, including what the service is, when to use it, some of its core features and terminology, and how it compares to other databases. 

To recap, DynamoDB is a fully managed, serverless, NoSQL database service. While AWS takes care of the maintenance and management of the underlying infrastructure, you are responsible for your data and how you model that data using tables, items, attributes, and your partition and sort keys. 

It is highly available by default, as it replicates your data between three Availability Zones. However, you can enable Global Tables for replication across Regions to create an active-active setup for faster performance. You can also use on-demand backups and point-in-time recovery for compliance, archiving, and greater durability of your data in case of human error. 

When you create a DynamoDB table, you can choose between on-demand capacity mode and provisioned throughput mode. While on-demand capacity mode handles the calculation and scaling of your RCUs and WCUs transparently, it also comes at an additional cost. 

You can interact with DynamoDB using four main methods: the AWS console, the AWS CLI, the AWS SDKs, and the NoSQL workbench for DynamoDB. These help you interact with the DynamoDB API through control plane operations, data plane operations, and transactions operations.

Control plane operations provide commands for managing your DynamoDB tables. Data plane operations provide commands for managing the data within those tables. And then transactions operations provide commands if you choose to use transactions for DynamoDB in order to have ACID compliance.
