Using Versant – hands on distributed objects

Robert Greene

This 45 ` demo presents the use of the Versant object database. In particular, it shows how to take a pure in-memory Java application and make it fully persistent using Eclipse IDE. Further it shows how to make the application fault tolerant via synchronous replication with literally the click of a button, demonstrates object migration across physical databases while maintaining a fully connected object model in the application space, shows how to build and use a parallel query over a logical sub-grouping of physical databases. Finally, the demo ends with a quick into performance optimization and removal of the N+1 problem of network access to connected data.
