AS400 Application Development For Beginners

AS400, also known as IBM i, is a powerful platform used for application development. If you’re a beginner looking to start with AS400 application development, here are some key points to consider:

Understanding the Basics: Familiarize yourself with the fundamental concepts of AS400, including its architecture, file systems, libraries, and object-oriented nature. Gain an understanding of the green-screen interface and the different development tools available.

Programming Languages: AS400 supports multiple programming languages. Two commonly used languages are RPG (Report Program Generator) and COBOL. RPG is a high-level language specifically designed for business applications, while COBOL is a versatile language suitable for large-scale enterprise systems. Consider learning these languages to begin developing applications on AS400.

Development Tools: AS400 provides several development tools to assist programmers. The most commonly used one is IBM Rational Developer for i (RDi), an integrated development environment (IDE) that offers features like code editing, debugging, and performance analysis. Familiarize yourself with RDi and explore its capabilities.

Database Management: AS400 uses a database management system called DB2 for storing and managing data. Understanding how to work with DB2 is crucial for developing applications on AS400. Learn the basics of SQL (Structured Query Language) for querying and manipulating data within DB2.

Learning Resources: There are various resources available to learn AS400 application development. Consider online tutorials, documentation, forums, and books specifically focused on AS400 programming. IBM provides official documentation and training materials that can be helpful for beginners.

Hands-on Practice: To gain proficiency in AS400 application development, it’s essential to practice what you learn. Start with small projects or exercises to apply your knowledge and build your skills. Collaborate with experienced AS400 developers or join a community to get guidance and feedback on your work.

Stay Updated: AS400 has evolved over the years, so it’s important to stay updated with the latest advancements and features. Follow relevant blogs, forums, and websites to stay informed about the latest developments in AS400 application development.

Remember, becoming proficient in AS400 application development requires time, practice, and continuous learning. Start with the basics, gradually expand your knowledge, and explore real-world projects to enhance your skills.
