Penguin is an object-oriented interface to relational databases. Penguin has its own simple language-independent object model with inheritance for composite objects defined as views (called view-objects) of a relational database. These view-objects represent data according to application requirements in such a way that multiple applications can share overlapping, but different, sets of data. Multiple applications may share data by having overlapping schemata with differing composite objects and differing inheritance mappings. We have a C++ binding, which supports multiple inheritance. The result is a framework for collaboration among multiple users, each with differing perspectives about the system and its data.
