These slides are designed to accompany Software Engineering: A 2 Design Patterns Each of us has encountered a design problem  and silently thought:  I wonder if anyone has  developed a solution to for this? What if there was a standard way of describing a  problem (so you could look it up), and an organized  method for representing the solution to the problem?  Design patterns   are a codified method for  describing problems and their solution allows  the software engineering community to  capture design knowledge in a way that  enables it to be reused.

These slides are designed to accompany Software Engineering: A 3 Design Patterns Each pattern describes a problem that occurs over  and over again in our environment and then  describes the core of the solution to that problem in  such a way that you can use the solution a million  times over without ever doing it the same way  twice. Christopher Alexander, 1977 “a three-part rule which expresses a relation  between a certain context, a problem, and a  solution.”

These slides are designed to accompany Software Engineering: A 4 Basic Concepts Context  allows the reader to understand the  environment in which the problem resides and  what solution might be appropriate within that  environment.  A set of requirements, including limitations  and constraints, acts as a  system of forces  that  influences how  the problem can be interpreted within its context and  how the solution can be effectively applied.

These slides are designed to accompany Software Engineering: A 5 Effective Patterns Coplien [Cop05] characterizes an effective design pattern in  the following way: It solves a problem : Patterns capture solutions, not just abstract principles or strategies. It is a proven concept : Patterns capture solutions with a track record, not theories or speculation.

"Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
