Comparison ETL Vs ELT
•
0 likes•6 views
👉 ETL and ELT are three-phase process types of data processing that are used in data integration and data analytics. 👉 ETL stands for Extract, Transform, and Load. 👉 ELT stands for Extract, Load, and Transform. 👉 Both ETL and ELT use similar steps to process data. 👉 The key difference between these two is the fact that with ETL you have to first load the data into your database before it can be transformed, while with ELT you can just do the transformation without loading any data at all.

➤ Django for Python Developers
➤ Express.js for JavaScript Developers
➤ ASP.NET core for .NET developers
➤ Laravel for PHP Programmers
➤ Ruby on Rails for Ruby Programmers

What Is BootStrap?
A free and open source front-end development framework called Bootstrap.
It is used to build websites and web applications.
The main goal of this utility was to build a tool that helps in the development of website-related applications fast, easy, convenient and more responsive.
Its availability of many size, color, font, and layout options for the project was the main factor in its inclusion in the Bootstrap framework.
Comparison Between Excel Vs SQL
➤ Microsoft Excel was developed by Microsoft Corporation in 1994 and is used to present numeric and statistical data in a tabular form.
➤ SQL was developed in the 1970s by IBM researchers Raymond Boyce and Donald Chamberlin to extract, organize, manage & manipulate data stored in relational databases.
➤ Excel is a spreadsheet or worksheet file made of rows and columns that help sort, organize, and calculate numerical data.
➤ SQL is a query language used to manipulate databases and get information stored in a relational database management system (RDBMS).
➤ Excel is helpful for producing quick data summaries and visualizations
➤ SQL is needed to work with large volumes of data, manage databases, and use relational databases to their full potential.
➤ Microsoft Excel is used in business analyst roles for quick calculations, data summaries, and data visualizations.
➤ Data analysts use SQL to take care of large databases and find important and relevant data for business use.
➤ In Microsoft Excel, even slightly more than 100,000 will probably cause your computer to slow down.
➤ SQL does not slow down with larger data sets depending on the software and database.
In Excel, your data is saved in a file that is typically set up with tabs, columns, and rows on your computer.
➤ You make SQL queries and send them to the database. The database gets them and either fulfills your requests or changes them.
➤ Excel does not include encryption features for protecting sensitive data such as personally identifiable information, financial data, etc.
➤ The SQL database is designed to be a secure database platform. It has a number of features that can encrypt data, limit access and authorization, and keep data from being stolen, destroyed, or used in other bad ways.
➤ Excel spreadsheets are susceptible to small human mistakes.
➤The most common SQL error is a syntax error.
How to visualize Number using Python Library
Matplotlib is a popular
Python library that is used
to create 2D plots.
It takes data from an array of
numbers and generates a plot
in the form of a graph or
image.
Matplotlib provides many methods to visualize
numbers and their squares using different colors,shapes, and graphs.
Comparison Between Java And Python
👉 Java and Python are two of the most popular programming languages. In this Java vs. Python comparison, we examine how the two languages compare to one another.
👉 Python is an object-oriented language, whereas Java is a procedural language, which is the primary distinction between the two. Both are excellent languages for developing web apps.
👉 Python comes in first on the TIOBE index's list, whereas Java comes in third.
👉 Python is an interpreted and dynamically typed language, while Java is a statically typed and compiled language. Java runs faster and is simpler to debug, but Python is simpler to use and read.
Hybrid Cloud Vs Multiple Cloud
👉 Multi-cloud is a combination of on-premise, public, and private clouds.
It can be a combination of Saas, PaaS & IaaS Services.
👉 Hybrid cloud computing is a service that delivers the best of both private and public cloud features. You get the security of a private cloud. But you also get the elasticity, flexibility, and cost savings of a public cloud.
A hybrid cloud combines both public and private clouds to give customers additional flexibility and greater control over their computing environment.
This solution allows an organization to take advantage of private cloud economies (such as a more streamlined on-premises IT infrastructure) while still providing the elasticity and agility of a public cloud.
Hybrid cloud computing enables enterprises to achieve higher availability, better performance, more functionality, and higher security.
Comparison Between react js & react native
There are some major differences between Reactjs and Native React.
Take a look at following👇
👉 Reactjs is a JavaScript library that allows programmers to design an engaging and high-performing user interface layer, whereas React Native is a complete framework for developing cross-platform apps for the web, iOS, and Android.
👉 React Native is similar to React, but instead of using web components as building blocks, it uses native components. Rather than the browser, it is focused on mobile platforms.
👉 React is the base abstraction of React DOM for the web platform in React JS, whereas in React Native, React is the base abstraction of React Native. As a result, the syntax and workflow stay the same, but the components do not.

What is Big Data Pipe?
"Data pipelines" are a collection of processes that transmit data from one location to another location.
The end-to-end process of gathering data, turning it into insights and models, disseminating insights, and applying the model whenever and wherever the action is required to achieve the business goal is stitched together by a data pipeline.
Architects and developers have had to adjust to "big data" because of the significantly increased volume, diversity, and velocity of data in recent years.
What is Big Data?
Big Data is a collection of large amounts of complicated or unstructured data that is difficult to process using typical data processing software or on-hand database management solutions.
There are five defining properties that can help break down Big Data.
And these five characteristics that define big data are volume, variety, velocity, value and veracity.

How AWS Lambda Works
AWS Lambda runs code in response to events and automatically manages the compute resources.
It can be used in various ways, including as a trigger for other AWS services.
Lambda is a pay-as-you-go service, so you only pay for what you use. You are charged based on the number of requests for your functions as well as the time it takes for your code to execute.

3 V's of Big Data
There are three defining properties that can help break down Big Data.
And these three characteristics that define big data are volume, variety, and velocity.
Data volume-
The volume of data is simply the size of the data and is typically characterized by the amount of information a dataset contains (megabytes, gigabytes, etc.).
Data velocity-
It refers to the rate at which data is generated and transferred.
Data variety-
Big Data variety refers to all structured and unstructured data that may be generated
by people or machines.
