Using the database directory class is a great way to collect database statistics for a given server. By using getFirstDatabase and getNextDatabase, a subset of the database information can be retrieved without actually opening the database. This information includes database title, type, path, name, size and other various properties. The java class works very quickly and can collect data for all databases on a server within seconds. You could use this class to write statistics using a JDBC connection, and/or to collect data periodically for statistical growth charts or monitoring.
