 Amazon Relational Database Service (AWS RDS) makes it easy to set up, operate, and scale a relational database in the cloud. Instead of managing servers, patching OS, and handling backups manually, AWS RDS takes care of the heavy lifting so you can focus on building applications and data pipelines. In this blog, we’ll walk through how to create an AWS RDS instance , key configuration choices, and best practices you should follow in real-world projects. What is AWS RDS? AWS RDS is a managed database service that supports popular relational engines such as: Amazon Aurora (MySQL / PostgreSQL compatible) MySQL PostgreSQL MariaDB Oracle SQL Server With RDS, AWS manages: Database provisioning Automated backups Software patching High availability (Multi-AZ) Monitoring and scaling Prerequisites Before creating an RDS instance, make sure you have: An active AWS account Proper IAM permissions (RDS, EC2, VPC) A basic understanding of: ...

Blockchain Technology: 11 Exclusive Benefits

-
Here are the benefits of blockchain technology. Less maintenance and its distributable nature made the blockchain technology hot in the market.  


Benefits
 
The applications that used blockchain technology Viz: Banks, Share markets, Government Bodies, and Big Corporations. 

What is Blockchain

Blockchain stores each transaction in Blocks. No one can tamper or change the details. The people who are making a transaction in the Blockchain world both have the same copies. he parties involved cannot changes these records. So it is robust.

Advantages of distributed ledger technology (Blockchain)

  1. The distributed nature of ledger details.
  2. Distributed data available to all parties, and cannot tamper the data.
  3. Every transaction is Public. That means only people who have access can see the information.
  4. It stores all records permanently.
  5. One cannot edit or manipulate the data.
  6. Data-hacking is not possible since it is distributed.
  7. Unlike centralized processing, the Blockchain is much faster. And verification and completing a transaction are faster.
  8. Unlike centralized processing, it is less expensive. In the centralized system each server in the network charges some amount as a processing fee. Here you can eliminate intermediaries - so less expensive.
  9. The Centralized databases are expensive to carry transactions of low value. The fee to pay intermediaries is more.
  10. The Data in the Blockchain is not editable. In the case of Centralized databases, the Banks or Private Organizations can edit them.
  11. The maintenance of Blockchain is cheaper.

Disadvantages

  • Publish carefully. Once publishes you can't take back

Step-by-Step Guide to Reading Different Files in Python

-
Image
 In the world of data science, automation, and general programming, working with files is unavoidable. Whether you’re dealing with CSV reports, JSON APIs, Excel sheets, or text logs, Python provides rich and easy-to-use libraries for reading different file formats. In this guide, we’ll explore how to read different files in Python , with code examples and best practices. 1. Reading Text Files ( .txt ) Text files are the simplest form of files. Python’s built-in open() function handles them effortlessly. Example: # Open and read a text file with open ( "sample.txt" , "r" ) as file: content = file.read() print (content) Explanation: "r" mode means read . with open() automatically closes the file when done. Best Practice: Always use with to handle files to avoid memory leaks. 2. Reading CSV Files ( .csv ) CSV files are widely used for storing tabular data. Python has a built-in csv module and a powerful pandas library. Using cs...

SQL Query: 3 Methods for Calculating Cumulative SUM

-
Image
SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than...
