Algorithmique : Conception descendante, Cobol IBM AS400

Are you considering a career change? Unlock your potential with computer programming skills! Don't underestimate the power of knowledge – it directly translates to increased earning potential in today's job market. Investing in IT skills is a smart move.

I'm Allé DIENG, a seasoned expert with a background in computer science and management, holding degrees from POLYTECH Montpellier and Sorbonne Université Paris. My goal is to empower you with practical, in-demand skills, drawing on my experience with systems like IBM AS400/iSERIES (with over 100,000 installations worldwide).

This course focuses on building robust and efficient programs, applicable directly to real-world business scenarios. You'll gain a rapid return on your investment by learning to develop high-quality software solutions.

Here's what you'll learn:

• Algorithmic Design (Sections 1-3): Master the art of creating well-structured, modular, and performant programs – skills transferable across all programming languages.
• Technical Documentation (STD): Learn to create detailed specifications for your programs, ensuring clarity and maintainability.
• Manual Testing: Develop a rigorous testing process to validate your code before writing it, minimizing costly errors later. Early bug detection significantly reduces correction costs (potentially by a factor of 100!).
• Code Optimization: Avoid "dead code" and ensure every part of your program is utilized for optimal performance.
• Data Access Strategies: Understand the advantages of sequential data access over direct access, and the significant time savings it provides. We'll explain the cost implications of direct access.
• The Importance of Design & Testing: Discover how effective design and thorough testing dramatically reduce development and maintenance costs. I'll share a compelling example of a program redesigned to reduce execution time from 34 hours to just 10 minutes!
• COBOL Programming (Sections 4-13): Translate your algorithmic designs into functional COBOL code, a powerful and widely understood programming language.

This course is designed for anyone looking to acquire practical programming skills and advance their career in the IT industry. Ready to embark on your computer programming journey?
