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

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.

Document Stores
PHP 7.0+
2
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.

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.

Data Mapper vs Active Record
Two ORM patterns: Active Record bakes persistence into the domain object itself; Data Mapper separates the domain object from its persistence mechanism.

Data Transfer Object (DTO)
PHP 8.0+
A simple object that carries data between layers or systems with no business logic — reducing coupling between layers and making data contracts explicit.

Database Partitioning
PHP 5.0+ Splitting a large table into physical segments by range, list, or hash — enabling partition pruning, faster archival, and parallel scans.

Database Schema Design
PHP 5.0+
5
The process of defining tables, columns, data types, constraints, and relationships — decisions made at schema design time are expensive to reverse once data is live.

Database intermediate
Database Sharding
PHP 5.0+ Horizontally partitioning data across multiple database instances by a shard key, scaling write throughput beyond a single server's limits.

DDD Aggregates & Aggregate Roots
1
A cluster of domain objects treated as a single unit with one root entity controlling access and enforcing invariants across the cluster.

DDD Domain Services
Domain logic that doesn't naturally belong to any single entity or value object — cross-entity operations modelled as stateless service classes.

DDD Repositories vs Active Record
Repository pattern separates persistence from domain logic — the opposite of Active Record where the model knows how to save itself.

DDD Value Objects in PHP
Immutable objects defined by their attributes rather than identity — Money, Email, Coordinate — that encapsulate validation and domain behaviour.

Defence in Depth
PHP 5.0+
1
Layering multiple independent security controls so that bypassing one does not compromise the whole system.

General intermediate
Domain Events
PHP 7.0+
5
Named, immutable records of something that happened in the domain — 'OrderPlaced', 'PaymentReceived' — enabling decoupled reactions without direct service calls.

Domain-Driven Design (DDD)
PHP 5.0+
3
An approach to software development that focuses on modelling the core domain using the language and concepts of domain experts.

Dependency Injection
PHP 5.0+
3
Passing dependencies into a class rather than creating them inside — makes classes testable and loosely coupled.
