Using Java to add “stored procedures” to databases

The paper describes our approach to adding “stored procedure” capability to a semantic database system using Java byte codes and Java´s ability to dynamically load and execute Java code. Several steps were necessary: first we added a Java application programmer interface to the database system; then we created a database schema to hold Java executable code; then we constructed a Java class loader to allow code to be loaded from the database; then we enabled the creation of Java objects and executed the Java code for them. Our approach is not specific to our semantic database system, rather it can serve as a recipe for adding “stored procedures” to any database system
