Lattice Set

1. Problem Statement

As Ruby programs become larger, managing information through separate methods and collections can become difficult. Related operations may be scattered across different parts of the code, making their relationships harder to understand. Classes and objects introduce a different approach to organizing data and behavior. However, concepts such as initialization, encapsulation, and object interaction require careful explanation. A structured introduction helps learners understand how object-oriented programming supports application organization.

2. Solution

Lattice Set presents object-oriented Ruby concepts through ten connected learning modules. Each section combines theoretical explanations with practical examples demonstrating how objects manage data and behavior. Learners examine class definitions, instance methods, constructors, encapsulation, and relationships between objects. Guided exercises demonstrate how to organize application components and validate changes to object state. The course concludes with a practical project focused on a structured learning topic catalog.

3. What's Inside?

Module 1 — Introduction to Object-Oriented Programming

Explore object-oriented principles and understand how Ruby classes organize related data and behavior.

Module 2 — Classes and Objects

Learn to define classes, create instances, and examine the differences between class definitions and individual objects.

Module 3 — Constructors and Initialization

Use initialize to configure object attributes and establish initial values when creating instances.

Module 4 — Instance Variables and Methods

Work with instance variables, define object behavior, and organize operations within class methods.

Module 5 — Encapsulation and Data Control

Explore public and private methods, attribute readers, and controlled changes to internal object data.

Module 6 — Object State and Validation

Examine object state, validate incoming values, and manage changes while maintaining consistent records.

Module 7 — Object Relationships

Learn how objects exchange information, call methods, and cooperate within a connected program.

Module 8 — Collections of Objects

Organize multiple objects using arrays and hashes, retrieve records, and process structured collections.

Module 9 — Class Organization and Responsibilities

Explore the separation of responsibilities, meaningful method names, and approaches to organizing related classes.

Module 10 — Practical Ruby Project

Develop an object-oriented learning topic catalog with classes for managing records, validating data, and coordinating operations.
