Conclusions
Messaging and database technology have evolved independently. There have been early attempt to use databases to store messages without adapting the database technology to the messaging environments New Era of Networks Integration Package. These attempts resulted in severe performance and functional limitations.
Oracle’s approach finally brought the breakthrough. The approach presented in this paper achieved the following benefits
• Significantly extended the information sharing functionality
• Significantly improved the operational characteristics
• Significantly reduced TCO (Total Cost of Ownership) for users
• Significantly reduced development time and effort for Oracle
The Oracle effort confirmed the perception of many researchers that messaging and database technology should be integrated Implementing Recoverable Requests Using Queues, Transaction Processing. It also adds a new perspective to the work related to active databases as described in Active Database Systems.
