Delphi – Applying MVVM Pattern, POCO class, Repository, UseCases, SOLID principles and Clean Code 09

Delphi – Applying MVVM Pattern, POCO class, Repository, UseCases, SOLID principles and Clean Code 10    • Delphi – Applying MVVM Pattern, POCO class...   MVVM Pattern: Clear separation of responsibilities between the user interface and presentation logic. Model as a POCO class: Domain definition decoupled from frameworks or persistence. UseCase Pattern: Centralization and isolation of business rules. Repository Pattern: Complete abstraction of the data and persistence layer. SOLID Principles and Clean Code: Coding best practices to ensure clean, readable, and decoupled code. Introduction and Objective: A brief introduction explaining that the series will demonstrate how to build robust, testable, and maintainable applications by applying the MVVM architecture in practice. Embarcadero Object Pascal Delphi refers to the combination of the Object Pascal programming language and the Delphi integrated development environment (IDE), both developed and maintained by Embarcadero Technologies. Object Pascal is a dialect of the Pascal programming language that incorporates object-oriented programming (OOP) features. It provides concepts such as classes, inheritance, polymorphism, and encapsulation, enabling developers to create modular and reusable code. Embarcadero Delphi is a rapid application development (RAD) environment that utilizes Object Pascal. It provides a visual development approach, allowing developers to design user interfaces and connect them to back-end logic and data sources. Delphi supports the creation of applications for various platforms, including Windows, macOS, iOS, Android, and Linux, primarily through its Visual Component Library (VCL) for Windows desktop applications and the FireMonkey (FMX) framework for cross-platform development. In essence, Embarcadero Object Pascal Delphi represents a powerful and comprehensive solution for building native, high-performance applications across multiple platforms using a modern, object-oriented Pascal dialect. Delphi: Modern Object Pascal Delphi offers modern Object Pascal with native compilers and component libraries for Windows, macOS, iOS, Android and Linux. Delphi was originally written by Anders Hejlsberg before he moved to Microsoft to father C# Sharing a common ancestry, C# developers find themselves immediately at home in using Delphi. Full of modern language constructs, including reflection and attributes, anonymous methods and generics, Delphi offers developers an easy to read, learn and use fully featured Object Oriented language.
