1 sessionDescription
The accredited iSAQB® FUNAR training introduces you to functional software architecture as an alternative and complement to object-oriented approaches. You will learn core concepts such as immutable data, higher-order functions, algebraic abstractions, and embedded domain-specific languages. Using architectural examples, domain models, and exercises, you will examine how functional principles can reduce dependencies and make architectures easier to understand. The course prepares you for the iSAQB® FUNAR module and helps you place functional decisions in the design, evaluation, and evolution of software architectures.
What You Will Learn
This accredited training is based on the iSAQB® curriculum for FUNAR at the Advanced Level. After completion, you can have 10 credit points credited in the methodology competence area and 20 credit points in the technical competence area.
Part 1: Basics of Functional Programming
Basic principles of functional programming, including immutability, higher-order functions, and referential transparency
Differences from object-oriented and procedural approaches
Effects of functional concepts on maintainability, testability, and architectural decisions
Part 2: Technologies
Overview of functional languages and functional approaches in existing platforms
Typical libraries, runtime environments, and tools in the context of functional software development
Criteria for selecting suitable technologies in architectural projects
Part 3: Functional Modeling
Modeling business logic with functions, types, and data flows
Handling side effects, errors, and state changes
Structuring models for understandable and verifiable architectural designs
Part 4: Functional Macro Architecture
Architectural styles and design patterns for functional systems
Integration of functional components into existing systems
Evaluation of quality requirements such as changeability, reliability, and testability
Part 5: Continuous Example
Application of the concepts using an architectural example
Discussion of typical design decisions and possible trade-offs
Applying the content to your own practice in software architecture and development
Certification & Exam
After completing an accredited iSAQB® FUNAR training, you receive an iSAQB certificate of attendance with 20 credit points in the technological competence area and 10 credit points in the methodical competence area. The FUNAR module does not lead to its own certificate, but counts toward the CPSA-A certification of the iSAQB®.
For CPSA-A admission, you also need a valid CPSA-F certificate, relevant professional experience, a total of at least 70 credit points from the competence areas of technology, methodology, and communication, as well as a successfully passed CPSA-A exam. You can find details at the official source: iSAQB® FUNAR.
What You Will Achieve
This course teaches how to apply functional programming principles to software architecture. Participants learn to build maintainable systems by defining architecture through code and high-level abstractions.
Model domains using algebraic data types and pattern matching.
Design modular systems through functional composition.
Manage application state and side effects in functional frameworks.
Use persistent data structures to improve software reliability.
Apply architectural patterns through practical exercises in Haskell.
The training compares functional and object-oriented methods. While exercises use Haskell, the principles apply to Scala, F#, and Clojure. A one-day Haskell refresher is available if needed.
This course grants 20 technical and 10 methodological credit points toward the iSAQB Certified Professional for Software Architecture (CPSA) Advanced Level.
