Package com.bigdata.relation Description

This package includes an abstraction layer for relations. Each relation is backed by one or more indices - it essentially a logical container for those indices. (A relation can exist within a logical container as well). The relation is capable of selecting the most efficient index for query given a predicate that specifies a query constraint. Mutable relations have insert and delete operations in addition to query.
