Software Architecture styles

All

Architecture styles define the overarching structure and design principles for software systems. Choosing the right style impacts scalability, maintainability, and performance. Below is an overview of major architecture styles commonly used in software development: 1. Layered Architecture Description: Organizes the application into layers, each with a specific role (e.g., presentation, business logic, and data access).

GoF design patterns

All

The Gang of Four (GoF) Design Patterns, introduced in the book “Design Patterns: Elements of Reusable Object-Oriented Software”, provide a set of best practices for solving common software design problems. These patterns are grouped into three categories: Creational, Structural, and Behavioral. Here’s an overview of the GoF patterns and their implementation in .NET: 1. Creational

.Net data structures

All

.NET provides a wide variety of built-in data structures in its libraries to suit different application needs. These data structures are available primarily in the System.Collections, System.Collections.Generic, and System.Collections.Concurrent namespaces. Here’s an overview of the most commonly used data structures in .NET: 1. Non-Generic Collections Found in the System.Collections namespace, these work with objects, requiring

Algorithm complexity

All

Estimating the complexity of an algorithm involves determining how its resource usage (time or space) grows relative to the size of the input. This is typically expressed using Big O notation, which describes the upper bound of the algorithm’s growth rate. Here’s how you can estimate algorithm complexity: 1. Understand the Problem Identify Input Size:

Entity Framework data loading options

All

Entity Framework (EF) provides various data loading strategies to control how data is retrieved from the database. These strategies allow you to optimize performance and reduce the number of database queries. Here are the main options: 1. Lazy Loading Definition: Related data is automatically loaded from the database the first time it is accessed. How

Clean Architecture

All

Clean Architecture is a software design philosophy introduced by Robert C. Martin (Uncle Bob) that aims to create flexible, maintainable, and testable systems. It emphasizes separation of concerns and ensures that application components are independent of frameworks, UI, databases, or external libraries, making the system easier to adapt to changes over time. Key Principles of
