This article explains how domain‑driven design shifts database modeling from a data‑structure‑first approach to a domain‑model‑centric process, covering persistence of domain objects, the conversion of the four classic relational relationships and inheritance into tables, and the distinct strategies required for NoSQL databases.
This article explains how to correctly draw UML class diagrams by describing the six main relationship types—generalization, realization, aggregation, composition, association, and dependency—using clear examples and visual illustrations to help readers understand and apply each relationship in software modeling.
This article explains how to define and use Laravel Eloquent relationships—including one-to-one, inverse, and default model handling—by showing the necessary model methods, query constraints, and code examples for both sides of the association.
This article explains how to add, update, and manage related Eloquent models in Laravel—including saving single or multiple related records, using associate/dissociate for belongsTo relations, and handling many‑to‑many pivots with attach, detach, sync, toggle, and timestamp propagation.
