A Moose and a Fox Can Aid Scientists with Data Management Problems

Fox Finding Objects of eXperiments is the declarative query language for Moose Modeling Objects Of Scienti c Experiments, an object-oriented data model at the core of a scienti c experiment management system EMS being developed at Wisconsin. The goal of the EMS is to support scientists in managing their experimental studies and the data that are generated from them. Moose is unique among object-oriented data models in permitting sets to have relationships to classes other than their elements' class, in providing a construct for indexing collections by other collections, such as time series, and in distinguishing structural relationships from non-structural ones. Fox contains several new features necessary to manage experiments, such as support for associative element retrieval from indexed sets and highly expressive path expressions. Fox path expressions can traverse any relationship in the schema graph, including inheritance relationships, and in either direction of the ...
