Programming Foundations Training in Finland

This foundational Programming Foundations Training in Finland provides non-programmers, system administrators, and aspiring developers with a solid understanding of how computer systems work from a programmer’s perspective.

Participants learn core programming principles, data structures, and coding best practices using Python for exercises.
The course is language-neutral, preparing learners to transition into other languages such as Java, C#, or C++.

Regulatory Note (BDDK)

While not a regulatory course on its own, Programming Foundations supports
the Banking Regulation and Supervision Agency (BDDK) mandates — particularly
Article 20 (Secure Software Development) and Article 25 (Information Security Management)
— by instilling fundamental awareness of coding quality and secure development habits.

It is recommended for financial institutions as an introductory step toward
secure software development compliance programs.

By the end of this Programming Foundations Training in Finland, you will have gained knowledge and skills in the following areas:

• Understand computer and OS components.

• Work with data types, variables, and memory structures.

• Use operators and logical expressions effectively.

• Manage control flow, loops, and exceptions.

• Build modular programs with functions and libraries.

• Handle files and I/O operations safely.

• Write clean, readable, and maintainable code.

After completing this course, participants will:

• Have a clear understanding of software structure and execution,

• Be prepared to learn advanced languages like Java or C#,

• Possess the foundational knowledge required for BDDK-compliant secure coding practices.
