With the gushing rush of data flow, Amazon DynamoDB tutorial provides a non-SQL or non-relational database (commonly known as NoSQL) providing a mechanism for storage, processing and retrieval of data. It also allows graphs, documents, columns among its data model.
DynamoDB tutorial, being a NoSQL database, does not use the common structured query language. It provides fast and predictable performance with seamless scalability, offered by Amazon Web Services (AWS).
A user first stores the data in DynamoDB tables and then interacts with it through PUT and GET queries which are written and read operations, respectively.
DynamoDB consists of 3 basic units referred to as item, table and attribute.
The common terminologies related to DynamoDB are described as below;
Table, Items, Attributes
1. Primary Key
A unique attribute that is essential for the creation of a table is known as the Primary Key.
2. Simple Primary Key
A simple primary key is also known as the Partition key, and this is in real; a single attribute. DynamoDB with the help of the Partition key’s value to differentiate items inserted in the table. Example: Student ID in the Student Details table.
3. Composite Primary Key
A composite primary key is also referred to as the Partition Key, and the Sort key having 2 elements.
This is an add-on feature provided by Amazon DynamoDB tutorial to track any data modification events in the table in the database.
Accessing DynamoDB is very easy to access and can be accessed using the following methods:
DynamoDB is created uniquely so that the user can achieve high-performance and run multiple applications that would not be easily manageable with the traditional database system. These add-on features of DynamoDB can be accessed via the following modes:
1. On-demand capacity mode
2. Built-in support for ACID transactions
3. On-demand backup
4. Point-in-time recovery
5. Encryption at rest
DynamoDB is a database management tool. The Application Programming Interfaces in DynamoDB tutorial are:
Control Plane consists of operations responsible for “Creating” and “Managing” a DynamoDB table. The operations under DynomoDB that can be used are;
Data Plane consists of “CRUD” operation, i.e. “Create“, “Read“, “Update“, and “Delete” options to perform different actions on your table. Multiple operations can be done on a table. The operations here are as follows:
DynamoDB Stream is a service to track data stream already loaded and retrieved into a table. To modify the streaming, the user can use the following commands according to the requirement;
Some of the case studies are;
Let’s find out how to create a table in DynamoDB.
Step 1: Navigate to the DynamoDB section in AWS.
Step 2: Fill in with the necessary details and click on “Create“.
Step 3: You can view your table being created. Click on “Overview” to understand your table, click on “Items” to edit, insert and query on the table. There are many more options you can use to understand your table better.
Likewise, once the table is created, data can be inserted as per the requirements of the user.
For managing data, DynamoDB tutorial uses b-trees and hashing. And If I talk about the advantages, it includes complete control over the data, data being accessible at any point of time, no internet connectivity required, and most importantly, it’s free to use.
