Delphi/Object Pascal: Learning Path & Resources.

Delphi is a programming language that is based on Object Pascal, which is an extension of the Pascal programming language. It was developed by Borland in the mid-1990s as a rapid application development tool for Windows. Delphi/Object Pascal is still used today for developing desktop and mobile applications, as well as web applications and server-side software.

Prerequisites for Learning Delphi/Object Pascal:

Before learning Delphi/Object Pascal, it is recommended that you have a basic understanding of programming concepts like variables, data types, functions and control structures. Additionally, having some familiarity with OOP concepts can be helpful.

Step-By-Step Learning Path For Delphi/Object Pascal :

Here are the steps you can follow to learn Delphi/Object Pascal:

  1. Start with the official Embarcadero Delphi documentation ( This documentation covers all the basic concepts and syntax of the language, as well as the Delphi development environment.
  2. Work through some beginner-level tutorials on Delphi Basics (, which covers fundamental concepts of Object Pascal programming, such as variables, data types, and loops.
  3. Move on to advanced tutorials on Object Pascal programming on Delphi Praxis (, which covers topics such as class design, advanced memory management, and multithreading.
  4. Read some books on Object Pascal programming, such as Mastering Delphi by Marco Cantù ( and Object-Oriented Programming with Delphi by Guido Hornberg (
  5. Learn how to use the VCL (Visual Component Library), which is the library of user interface components that come with Delphi. The official Embarcadero documentation ( covers all the details of the VCL.
  6. Learn about database programming in Delphi. The official Embarcadero documentation ( covers how to work with databases using Delphi, as well as advanced topics such as data access components and data binding.
  7. Experiment with third-party libraries and frameworks for Delphi. Some popular libraries and frameworks include Indy (, which provides Internet connectivity components, and FireDAC (, which is a powerful database access library.
  8. Join the Delphi community, where you can ask questions, get help with problems, and connect with other Delphi developers. Some resources to consider include the Embarcadero community ( and the Delphi subreddit (
  9. Finally, continue to deepen your understanding of Object Pascal programming by reading the source code of existing Delphi projects. This can be a great way to learn about advanced language features and design patterns used in real-world applications.
