Observation Agent System

This distributed database observation system from Envion Software tracks database changes, stores them, and notifies users when they occur. The user simply specifies the conditions by which the data is considered to be changed. We designed the architecture and interface, and developed some of the applications for this Oracle 9i and IBM DB2-based solution. Most noteworthy about our design is that it is based on analyzing transaction logs, and not on using triggers which mar performance and entail extra maintenance. Our technical innovation enabled us to give the client a fast, clean, and lighter system.
