Object-to-Relational
Mapping Tool and Runtime Framework
Impetus has developed a Java-based object-to-relational
mapping tool similar to Sun's JavaBlend. This tool,
unlike other tools, provides for change notification to
aid development of live applications. It provides for rich
object relationship and inheritance mapping, lazy as well
as immediate fetching, object level transactions and a deep
query mechanism. The design permits for optimal use in two
tier and three tier configurations. The latter can be deployed
with complete caching to improve lookup performance.
