Aspect Oriented Programming and Design
1. Aspect-oriented programming (AOP) uses aspects to modularize code that implements cross-cutting concerns like transactions, persistence, and security. This avoids tangled code by separating these concerns from the core functionality. 2. Real applications mix multiple domains that intersect, but objects alone don't prevent this tangling. Aspects restore modularity by encapsulating the intersections of concerns like transactions, persistence, and security in separate aspects. 3. Common uses of aspects include persistence, transactions, security, and logging. The future of AOP may include better component architectures with improved separation of concerns, and better overall systems architectures using aspects with domain-specific languages.
