Three methods for representing data in a relational storage system with an in-core frame-based system are experimented with and reported upon. Tradeoffs among these three representational methods are sizes of databases, times for loading data, and performance of queries. Essentially, these methods differ in ways of capturing relationships among frames. The three different ways of capturing such...
