Java Movie Database is a Java-based application to search for information about movies, actors, actresses, producer, director and everything related to those.
Currently it counts over 1.577.000 movies and over 1.856.000 actors/actresses.
Beside this base data about movies and performer there is a lot of other data available and supported by the Java Movie Database application like plots, biographies, ratings, goofs and much more.
The difference between the IMDb and JMDB is, that the Java Movie Database is an alternative way to navigate through this information. It can be run on a stand-alone PC just as in a network environment. Another advantage is that you can write your own programs and scripts to use the locally installed database.
The JMDB will import the IMDb textfiles (also called IMDb list files) into the database system for you.
