Model-View-Controller (MVC) is a software architecture pattern that divides an application into three main components:
✔ Better maintainability through a clear separation of concerns.
✔ Reusability of components.
✔ Easy testability since logic is separated from the interface.
✔ Flexibility, as different views can be used for the same model.
MVC is widely used in web and desktop applications, including:
The Catalyst Framework is a flexible and powerful web framework for Perl. It enables the development of scalable and maintainable web applications and follows the Model-View-Controller (MVC) design pattern.
✅ MVC Architecture – Clear separation of business logic, presentation, and data management
✅ Flexibility – Supports various templating systems and ORM solutions like DBIx::Class
✅ Extensibility – Many plugins and modules available
✅ Asynchronous Capabilities – Can be integrated with event-driven architectures
✅ REST APIs & WebSockets – Support for modern web technologies
Beego is an open-source web framework written in programming language Go (Golang). It is widely used for building scalable web applications and APIs. Beego provides a comprehensive platform for developers to create both simple and complex applications quickly and efficiently.
Modular Design:

If you're considering using Beego, it's worth evaluating your project requirements and comparing it with alternative frameworks such as Gin, Echo, or Fiber to determine the best fit.
Meteor is an open-source JavaScript framework that allows developers to quickly and easily build web and mobile applications. It was released in 2012 by the Meteor Development Group (MDG) and is designed to streamline the development process while unifying code for both the frontend and backend. Meteor is particularly useful for real-time applications due to its reactive architecture.
JavaScript Everywhere:
Real-Time Functionality:
Isomorphic Code:
Built-in Database Support:
Easy Integration:
Fast Development Process:
Meteor is an excellent framework for developers aiming to create reactive, cross-platform applications quickly. It’s particularly well-suited for projects where real-time updates and rapid development are priorities.
Next.js is a React-based framework that simplifies the development of modern web applications. Developed by Vercel, it provides a wide range of features beyond what the React library offers. Next.js is especially appealing to developers who want to create powerful, scalable, and SEO-friendly applications.
Hybrid Rendering:
API Routes:
Built-in Routing:
pages folder becomes a route, e.g.:
pages/index.js → /pages/about.js → /aboutImage Optimization:
next/image component optimizes images automatically with features like lazy loading, resizing, and WebP support.TypeScript Support:
Fast Refresh:
Middleware:

MariaDB is a relational database management system (RDBMS) developed as an open-source alternative to MySQL. It was created in 2009 by the original MySQL developers after MySQL was acquired by Oracle. The goal was to provide a fully open, compatible version of MySQL that remains independent.
MySQL Compatibility:
Enhanced Features:
Active Development:
MariaDB is a powerful and flexible database solution, highly valued for its openness, security, and compatibility with MySQL. It is an excellent choice for developers and organizations looking for a reliable open-source database.
The MERN Stack is a collection of JavaScript technologies commonly used to build modern, scalable, and dynamic web applications. The name is an acronym that represents the four main technologies in the stack:
MongoDB (M):
Express.js (E):
React.js (R):
Node.js (N):
The MERN Stack is particularly popular among startups and companies looking to build fast, interactive web applications.
PSR-7 is a PHP Standard Recommendation (PSR) that focuses on HTTP messages in PHP. It was developed by the PHP-FIG (Framework Interoperability Group) and defines interfaces for working with HTTP messages, as used by web servers and clients.
Request and Response:
PSR-7 standardizes how HTTP requests and responses are represented in PHP. It provides interfaces for:
Immutability:
All objects are immutable, meaning that any modification to an HTTP object creates a new object rather than altering the existing one. This improves predictability and makes debugging easier.
Streams:
PSR-7 uses stream objects to handle HTTP message bodies. The StreamInterface defines methods for interacting with streams (e.g., read(), write(), seek()).
ServerRequest:
The ServerRequestInterface extends the RequestInterface to handle additional data such as cookies, server parameters, and uploaded files.
Middleware Compatibility:
PSR-7 serves as the foundation for middleware architectures in PHP. It simplifies the creation of middleware components that process HTTP requests and manipulate responses.
PSR-7 is widely used in modern PHP frameworks and libraries, including:
The goal of PSR-7 is to improve interoperability between different PHP libraries and frameworks by defining a common standard for HTTP messages.
PSR-2 is a coding style guideline for PHP developed by the PHP-FIG (Framework Interop Group) to make code more readable and consistent, allowing development teams to collaborate more easily. The abbreviation “PSR” stands for “PHP Standards Recommendation”.
{ for classes and methods should be on the next line, whereas braces for control structures (like if, for) should be on the same line.=, +).Here’s a simple example following these guidelines:
<?php
namespace Vendor\Package;
class ExampleClass
{
public function exampleMethod($arg1, $arg2 = null)
{
if ($arg1 === $arg2) {
throw new \Exception('Arguments cannot be equal');
}
return $arg1;
}
}PSR-2 has since been expanded and replaced by PSR-12, which includes additional rules to further improve code consistency.
A batch in computing and data processing refers to a group or collection of tasks, data, or processes that are processed together in one go, rather than being handled individually and immediately. It is a collected set of units (e.g., files, jobs, or transactions) that are processed as a single package, rather than processing each unit separately in real-time.
Here are some typical features of a batch:
Collection of tasks: Multiple tasks or data are gathered and processed together.
Uniform processing: All tasks within the batch undergo the same process or are handled in the same manner.
Automated execution: A batch often starts automatically at a specified time or when certain criteria are met, without requiring human intervention.
Examples:
A batch is designed to improve efficiency by grouping tasks and processing them together, often during times when system load is lower, such as overnight.
