Information Systems and Component Parts

The System Boundary vs. The Automation Boundary

The Analyst’s Approach to Problem Solving

Required Skills of the Systems Analyst

Object-Oriented Systems Analysis and Design  Software engineering approach  Models a system as a group of interacting objects  Object-Oriented Analysis (OOA)  Process of analyzing a task (also known as problem domain) to develop a conceptual model that can then be used to complete the task  Object-Oriented Design (OOD)  Mapping of the analysis model into implementation classes and interfaces to create a model of the solution domain (i.e., a detailed description of how the system is to be built)  Object-Oriented Programming (OOP)  Use to implement the solution  NOT what this course is about  What is covered in your C++, C#, Java, and Visual Basic courses
