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:
- Start with the official Embarcadero Delphi documentation (https://docwiki.embarcadero.com/RADStudio/Sydney/en/Main_Page). This documentation covers all the basic concepts and syntax of the language, as well as the Delphi development environment.
- Work through some beginner-level tutorials on Delphi Basics (http://delphibasics.co.uk/), which covers fundamental concepts of Object Pascal programming, such as variables, data types, and loops.
- Move on to advanced tutorials on Object Pascal programming on Delphi Praxis (https://www.delphipraxis.net/), which covers topics such as class design, advanced memory management, and multithreading.
- Read some books on Object Pascal programming, such as Mastering Delphi by Marco Cantù (https://www.amazon.com/Mastering-Delphi-Marco-Cantu/dp/1935308236/) and Object-Oriented Programming with Delphi by Guido Hornberg (https://www.amazon.com/Object-Oriented-Programming-Delphi-Guido-Hornberg/dp/3642056894/).
- 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 (https://docwiki.embarcadero.com/RADStudio/Sydney/en/Visual_Component_Library) covers all the details of the VCL.
- Learn about database programming in Delphi. The official Embarcadero documentation (https://docwiki.embarcadero.com/RADStudio/Sydney/en/Database_Programming) covers how to work with databases using Delphi, as well as advanced topics such as data access components and data binding.
- Experiment with third-party libraries and frameworks for Delphi. Some popular libraries and frameworks include Indy (https://www.indyproject.org/), which provides Internet connectivity components, and FireDAC (https://www.embarcadero.com/products/rad-studio/firedac), which is a powerful database access library.
- 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 (https://community.embarcadero.com/) and the Delphi subreddit (https://www.reddit.com/r/delphi/).
- 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.

What to Learn After Delphi/Object Pascal:
After learning Delphi/Object Pascal, it is recommended to learn about other programming languages that are commonly used in the same domains, such as Java, C++, or C#. Additionally, learning about web development frameworks like Angular or React can be helpful for those interested in web application development.
Top 5 Advantages of Delphi/Object Pascal:
- Delphi/Object Pascal is fast and efficient, making it an excellent choice for developing high-performance applications.
- Delphi has a powerful integrated development environment (IDE) that includes a visual form designer, code editor and debugger.
- Delphi has a large and supportive community that provides helpful resources and support.
- Delphi’s RAD tools allow developers to create applications quickly and easily, which is a major advantage for small to medium-sized projects.
- Delphi/Object Pascal is cross-platform, which means that applications can be developed for Windows, macOS, iOS and Android.
Top 5 Disadvantages of Delphi/Object Pascal:
- Delphi/Object Pascal is not as widely used as some other programming languages, which means that there may be fewer resources and support available.
- Delphi/Object Pascal is not as well-suited for large and complex projects compared to some other programming languages.
- Delphi/Object Pascal does not have as many libraries and tools available compared to some other programming languages.
- Delphi/Object Pascal’s syntax may be less familiar to developers who are used to other programming languages.
- Delphi/Object Pascal may not be the best choice for web development, as it is more commonly used for desktop and mobile applications.
