Design patterns

Design patterns

1. They began to be used in the architecture with the aim of reuse designs that had been applied in other constructions and that cataloged as complete.

   • ANTI-PATRONS
     • it is bad practice
       • There are two notions -Those who describe a bad solution -Those who describe how to get out of a bad situation and turn it into a good solution
         • Antipatrons of software development
           • The Blob
           • Lava Flow
           • Poltergeists
           • Golden hammer
           • Spaghetti code
           • Cut-and-paste programming
         • Antipatrons of software architecture
           • Stovepipe enterprise
           • Stovepipe system
           • Design by committee
           • Reinvent the Wheel
           • Arquitecture by implication

2. Paradigm for architecture

   • The quality
   • The door
   • The way

3. A pattern is the abstraction of a form concrete that can be repeated in contexts specific.

4. Characteristics

   • Solve a problem
   • Be a proven concept
   • The solution is not obvious
   • The pattern has a human component significant
   • Describe participants and relationships between they

5. Classes of patterns

   • -Patterns of architecture -Design patterns -Programming patterns -Patrons of analysis -Organizational patterns

6. Advantage

   • - Facilitate internal communication. - They save time and useless experiments. - Improve the quality of design and implementation.
