WIKI Topic - RDB/OO patterns
- It would be good if OO programs could interact with OO databases, but alas, relational databases have a 99% market share. This has led to many attempts to access them from OO languages. Design patterns for doing this have been developed, starting with Crossing Chasms and extending to Rails' ActiveRecord [1][2]. Here, we investigate the various approaches for marrying OO programs to relational databases, comparing them in terms of ease of programming, robustness, and efficiency.
Introduction
Relational Vs Object-Oriented Models
