Delphi Programming Tutorial – Lesson 4: Rapid Application Development

Delphi Programming Tutorial – Lesson 4: Rapid Application Development:

Rapid application development (RAD) is a general term used to refer to alternatives to the conventional approaches of software development.

Some of the Rapid Application (RAD) approaches to software development are:
– to emphasize the necessity of adjusting requirements in reaction to knowledge gained as the project progresses. This causes RAD to use prototypes in addition to or even sometimes in place of design specifications.

– to put less emphasis on planning tasks and more emphasis on program development.

– to emphasize a flexible process that can adapt as the project evolves rather than rigorously defining specifications and plans correctly from the start.

RAD is especially well suited (although not limited to) developing software that is driven by user interface requirements. Graphical user interface builders, like Delphi, are often called rapid application development tools.

Learn how Rapid Application Development (RAD) enables software developers to create big and impressive applications in a short time.

I want to thank everybody that participated in discussions – also to subscribers that sent “thank you’s” and words of encouragement. I’m a full-time Microsoft Certified Trainer at an IT college during the day, where I teach various programming languages and software development technologies. So, I only develop these videos lessons after-hours and in my free time – sometimes well into the night and early-morning hours.
YOUR words of appreciation and encouragement is what is driving me to want to continue with this service. YOU are the reason why I enjoy sharing my knowledge and skills – and for that, I THANK YOU!
PLEASE: If you enjoyed a video lesson, show your appreciation by clicking/tapping the “LIKE” button or link!! You are also welcome to leave a comment. These videos are for the world to see, so I will also appreciate it if you share it with all your friends and classmates! Please also “LIKE” our Facebook page at:

Like the lessons in Chapter 1, I will publish these videos on a lesson-by-lesson basis – in other words, when I’m finished developing a lesson, and after testing it, I will load it on YouTube. I try to complete at least one lesson a week, but sometimes you may have to wait a little longer. The lessons in Chapter 2 will also be jam-packed with easy-to-understand analogies, high resolution graphics and animations, and fun-to-follow practices!
 
If you have not subscribed to this channel yet, I hope you will do so immediately – please join me in all the fun!
 
All the videos in Chapter 1 is available in the following playlist:
