Big Data
Definition.
Big Data: Extremely large data sets that may be analyzed computationally to reveal patterns, trends, and associations.
In Practice
Most client projects never actually reach 'big data' scale — PostgreSQL with proper indexing handles the vast majority of production apps I've built. It's worth knowing the term mainly to recognize when a project genuinely needs a different toolset (and when it doesn't, which is more often).
