What is Interaction Design (IxD)?

Interaction Design (IxD) is the practice of designing interactive products to support how people communicate and interact in their everyday and working lives.

• Winograd: “Designing spaces for human communication and interaction.”
• Thackara: Focuses on the why and how of daily interactions.
• Saffer: “Art of facilitating interactions between humans through products and services.”

Key idea: It is about creating meaningful user experiences, not just functional systems.

What Is Programming?

Programming is a process consisting of a sequence of detailed and ordered steps called algorithms. We transcribe these instructions using a programming language (such as Python) so they can be executed by a computer to create an application or software.

Why Learn to Program?

Programming teaches you to think differently. Learning to code enhances your problem-solving skills, effectively rewiring your brain to tackle challenges not just in software development, but in all aspects

Software Development Life Cycle (SDLC)

The Software Development Life Cycle is a framework that defines how software is developed step by step.

Core Software Engineering Activities

• Software Specification
• Software Development
• Software Validation
• Software Evolution

Typical Development Flow

Planning → Requirements Analysis → System Design → Implementation → Testing → Maintenance

Software Process Structure

A Software Process consists of: Phase → Activity → Task

Process Activities Require:

• Resources

Part 1: Maintenance Method Cheat Sheet

When analyzing a scenario, ask yourself: Why are we performing maintenance on this machine?

1. Preventive Maintenance (Before Failure)

• Systematic (Periodic): Triggered by a strict interval (time, distance, operating hours, or cycles). The part is replaced regardless of its current condition.
  • Keywords: “Every X km,” “weekly,” “monthly,” “at 100,000 km,” “start of winter.”
• Condition-based: Triggered by physical warning signs, sensors, or thresholds. Action is taken

Relational Database Design and Normalization

The relational model stores data in tables (relations), where rows represent tuples and columns represent attributes.

• Key components: Tables, attributes, tuples, and constraints (PK, FK, UNIQUE, NOT NULL).
• Mapping ER to Relational: Entity becomes a table, 1:many uses a foreign key (FK) on the many side, many:many requires a junction table, and multivalued attributes move to separate tables.

Functional Dependency (FD): X → Y means X uniquely determines Y.
