الموضوعات المخطط لها

• A pattern is a named, reusable solution to a common design problem.
• It gives the team a shared vocabulary: "use a Strategy here".
• It is a recipe, not code to copy; you adapt it.
• Patterns are not goals. Do not use one when a simple function or class is enough.
• Many patterns are already in the JDK and Spring.
