InstantDB is a 100% Java, Relational Database Management System (RDBMS). Features supported include joins, transactions, triggers, sub-selects, table aliasing and much, much more that you wouldn't normally expect to find in a free RDBMS.
Since its launch in July 1997, InstantDB has been adopted by thousands of internet and database developers around the world. It is small, efficient, easy to install, and comes with lots of examples to help get the novice developer started. InstantDB is accessed via its own JDBC driver. By using standard SQL and Sun's JDBC API, InstantDB ensures that your applications enjoy a high degree of portability.
Lutris Technologies purchased InstantDB in April of 2000. The intent is to Open Source InstantDB in the near future, and create the most popular Open Source Java RDBMS.
InstantDB supports all of the the following features.What's Missing
Many of the above features will be included in later releases. If users have any particular preferences for the order in which these should be implemented then please feel free to say so.
All the classes were compiled using the 1.2 JDK. All deprecated methods have been removed. This release will only run on 1.1 or later JVMs. InstantDB and its JDBC driver have been tested with JavaPureCheck. Both are 100% Java.
