Object Orientation and Design Courses

Design systems that are easier to change

Many software problems do not start in the code. They start in the design. When systems are not structured clearly, the result is:

• Repeated bugs
• More difficult changes
• Long debugging cycles
• Higher maintenance costs

Object-oriented thinking helps teams design systems with clear roles and clear boundaries. This makes software easier to understand, test and change. UML is used as a simple way to show how parts of the system fit together. The goal is not more diagrams. The goal is fewer surprises later.

Improve structure with design patterns

Once OO principles are in place, design patterns help teams solve common design problems in a consistent way. A pattern is a proven design approach that reduces guesswork and makes code easier to maintain. Patterns are not tied to any one language. They help teams:

• Avoid fragile designs.
• Reduce duplicated effort.
• Make changes with less risk.
• Keep code behaviour predictable.

Our OO and design courses

Object-Oriented Analysis

This is for analysts who work with development teams. This course shows how to analyse and describe a system clearly using object-oriented thinking and UML. Clear analysis reduces misunderstandings before coding starts. This course runs in parallel with the first three days of the Object-Oriented Analysis & Design course.

Object-Oriented Analysis & Design

This is for programmers working in Java, C#, C++, and other object-oriented languages. You will learn how to analyse, design and document systems so that they are easier to change and maintain. The focus is on design decisions that reduce rework and avoid unnecessary complexity. The first three days run in parallel with the Object-Oriented Analysis course.

Design Patterns

This is for experienced object-oriented programmers. This course teaches you how to recognise common design problems and apply appropriate patterns. You will learn when patterns improve structure — and when they create complexity. The goal is clearer, more maintainable code.

Introduction to APIs and Web Services

Learn how APIs and web services enable systems to communicate and share data. This course covers REST and SOAP architectures, data formats like JSON and XML, and the principles of designing and consuming APIs. Ideal for developers and analysts working on system integration or service‑based design.
