Detailed Description

Dependency injection container for database components.

This class manages the lifetime and dependencies of database components. It replaces singleton pattern with dependency injection, enabling:

Testing with mock objects
Multiple independent database instances
Better separation of concerns
No hidden global state

Thread Safety: All methods are thread-safe. Component access is protected by internal synchronization.

Constructor & Destructor Documentation

◆ database_context() [1/3]

database::database_context::database_context ( )

Default constructor - creates default implementations.

Creates a context with default implementations:

Connection pool management (Sprint 3)
Performance monitoring (Sprint 3)
Other components as needed (Sprint 3+)

Note: For custom/mock implementations, additional constructors will be added in Sprint 3 when implementing other singleton conversions.

Examples: /home/runner/work/database_system/database_system/database/core/database_context.h.
