Systems Analysis Foundations: API Design, SQL, and Integration Architecture

Behind every successful software application is a systems analyst who translates complex business needs into clear, technical blueprints. If you want to bridge the gap between business goals and technical execution, understanding how IT systems communicate is your first critical step. This comprehensive text-based course guides you from the fundamental concepts of system architecture to the practical design of modern integrations. You will learn how data flows through networks, how databases store information, and how APIs connect independent services, giving you the skills to document robust requirements that development teams can immediately build. What you'll learn: - Understand key IT terminology, system architectures, and how clients and servers interact over HTTP and TCP/IP. - Write structured SQL queries to retrieve data and model data formats using JSON. - Design clean, modern REST APIs and document them professionally using the OpenAPI specification. - Analyze integration requirements and choose between synchronous REST calls and asynchronous communication patterns. - Document clear, unambiguous technical requirements and system schemas that developers can easily implement. You will start by exploring foundational networking and architectural concepts before diving into hands-on data modeling and API design. Through clear written explanations, practical scenarios, and structured exercises, you will build a solid technical foundation step-by-step. This course is designed specifically for aspiring systems analysts, business analysts transitioning to technical roles, and beginners with no prior technical background. Begin your journey into systems analysis today and learn to design the systems of tomorrow.
