The SOLID Principles, popularized by Robert C. Martin, were a topic of discussion in one of my classes this year. So far that class has largely followed on design patterns so Martin’s SOLID principles fit in well.
Via Uncle Bob’s twitter account, I read about reordering the principles in their order of significance. So, perhaps instead of the SOLLD principles, we should call them the SDOLI principles.
Overall, I’ve found these principles to be informative and definitely worth keeping in mind as one designs and implements a piece of software.
