What is Java Blend and how does it relate to JDBC?
Joe Sam Shirah JDBC is a relatively low level means of accessing tabular data. This was actually one of the goals of the specification and there was an explicit expectation that alternate tools could and would be built on top of the API. Java Blend is Sun's commercial offering in this area. It claims to achieve transparent persistence across multiple databases, to provide object-relational mapping that overcomes the "impedance mismatch", and to eliminate the need for SQL and even JDBC programming, among other things.
