Concurrency vs Parallelism
Concurrency is about dealing with multiple tasks at once (structuring); parallelism is actually executing multiple tasks simultaneously (hardware). You can have one without the other.

CQRS Pattern PHP 7.0+
Command Query Responsibility Segregation — separating the write model (commands that change state) from the read model (queries that return data), allowing each to be optimised independently.

Event Sourcing vs Messaging
Event sourcing stores all state changes as immutable events (the source of truth) — messaging delivers events between services. They complement each other but serve different purposes.

IoC Container PHP 7.0+
An Inversion of Control container automatically resolves and injects class dependencies — you declare what a class needs, the container figures out how to create it, eliminating manual dependency wiring.

Message Queue Patterns
Core messaging patterns — competing consumers, scatter-gather, request-reply, message filter, and routing slip — solve recurring distributed communication challenges.

MVC Pattern PHP 5.0+
Model-View-Controller — an architectural pattern separating data (Model), presentation (View), and request handling (Controller), the foundation of Laravel, Symfony, and most PHP frameworks.

OLAP vs OLTP
OLTP (Online Transaction Processing) optimises for many small, fast read/write operations — your main application database. OLAP (Online Analytical Processing) optimises for few, large analytical queries scanning millions of rows — your reporting and analytics database.

PHP Execution Model — Shared-Nothing Architecture PHP 5.0+
Each PHP request runs in a completely isolated process or thread — no memory, globals, or state is shared between requests. Every request bootstraps the entire application from scratch and discards everything when it ends.

Aggregate Design Heuristics PHP 7.0+ Rules for sizing aggregates correctly — small aggregates with single-entity transactions, referencing other aggregates by ID, and designing boundaries around invariants not convenience.

API Composition Pattern
An API layer aggregates parallel service calls into a single client response — reducing N round trips to 1 and improving perceived latency.

Backends for Frontends (BFF) PHP 7.0+ A dedicated API layer per frontend client (mobile app, web app, third-party) — each BFF aggregates and transforms microservice data for its specific client's needs.

Cloud-Native Patterns PHP 5.0+
Stateless services, externalised config, health checks, graceful shutdown, and immutable infrastructure — the 12-Factor App extended for containers.

Conformist Pattern
A context mapping relationship where the downstream team adopts the upstream team's model wholesale — accepting the upstream language rather than building a translation layer.

Data Mesh Architecture
Decentralised data architecture where domain teams own and publish their data as products — replacing centralised data lakes that create engineering bottlenecks.

architecture advanced
Database Triggers PHP 5.0+ Stored procedures that fire automatically on INSERT, UPDATE, or DELETE — useful for audit logs and enforcing constraints, but dangerous when they become hidden business logic.

database intermediate
Document Stores PHP 7.0+
Databases that store semi-structured documents (JSON/BSON) — MongoDB, CouchDB — flexible schema, nested data, and horizontal scaling at the cost of no joins and eventual consistency.

database intermediate
Domain Model Pattern
An object model of the domain that incorporates both behaviour and data — entities with methods expressing domain operations rather than just data containers.

Event Bus Patterns PHP 7.0+
Patterns for routing events between publishers and subscribers — in-process event buses (Symfony EventDispatcher), message broker buses (RabbitMQ, Kafka), and hybrid architectures.
