Image
 Here are some key terms commonly used in data pipelines 1. Data Sources Definition: Points where data originates (e.g., databases, APIs, files, IoT devices). Examples: Relational databases (PostgreSQL, MySQL), APIs, cloud storage (S3), streaming data (Kafka), and on-premise systems. 2. Data Ingestion Definition: The process of importing or collecting raw data from various sources into a system for processing or storage. Methods: Batch ingestion, real-time/streaming ingestion. 3. Data Transformation Definition: Modifying, cleaning, or enriching data to make it usable for analysis or storage. Examples: Data cleaning (removing duplicates, fixing missing values). Data enrichment (joining with other data sources). ETL (Extract, Transform, Load). ELT (Extract, Load, Transform). 4. Data Storage Definition: Locations where data is stored after ingestion and transformation. Types: Data Lakes: Store raw, unstructured, or semi-structured data (e.g., S3, Azure Data Lake).

Python 'getsizeof' Command the Real Purpose

-
Here's a sample python program to get the size of a List array.  Getting the number of elements present in a List is not easy. So how to get this? To do you need the 'getsizeof' command.

Import 'sys' Library.

You need to import the 'sys' library to use the SIZE commands. 

>>> import sys

Congrats to you since you have now imported the SYS library. The command name is "getsizeof".

Check the below example.

print("An Integer:")
i = int(100)
print(sys.getsizeof(i))

The result will be: 100

What is the size command?  - is to get the size of elements. It gives the result based on the object you are being used. Suppose, if you use Strings, you will get String length.

Python Command to get the Size of an Object


How to use the 'getsizeof' command?

Example:1

print("Empty string:")
empty_string = ""
print(sys.getsizeof(empty_string))

Example:2

print("A normal string")
s = "Hello world"
print(sys.getsizeof(s))

Example:3

print("Increasing string:")
for i in range(0,5):
empty_string = empty_string + chr(i)
print(sys.getsizeof(empty_string))

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...
