Introduction to AWS DynamoDB | Beginners guide for AWS DynamoDB

In this video, we learn about Dynamodb introduction and DynamoDB Core Concepts:
1. Tables: DynamoDB organizes data into tables, which are similar to tables in a relational database. Each table consists of multiple items, and each item is uniquely identified by a primary key.
2.Items: An item is a collection of attributes that represents a single data record in DynamoDB. Each item is identified by a primary key. Items can have other attributes in addition to the primary key.
3.Attributes: Attributes are key-value pairs that represent the data in an item. Each attribute has a name and a value. DynamoDB supports various data types for attribute values, including strings, numbers, booleans, lists, and maps.
4.Primary Key: A primary key uniquely identifies each item in a table. It can be composed of one or two attributes:
5.Partition Key: A simple primary key consists of a partition key, which is a single attribute used to distribute data across multiple partitions for scalability.
6.Partition Key and Sort Key: A composite primary key consists of a partition key and a sort key. The combination of both values must be unique within the table, allowing efficient querying and sorting of data.
