Trace based method for the analysis, benchmarking and tuning of object oriented databases and applications

A method for simulating the execution of an application with an object oriented database management system (OODB), comprising the steps of:

• (a) augmenting code comprising the application, producing augmented code, the augmented code including new instructions that enable the application to produce an application execution trace and a database layout trace;
• (b) executing the augmented code with a database on the OODB, the execution of the augmented code producing the application execution trace and the database layout trace;
• (c) employing a simulator to simulate the execution of the application with the database on the OODB, the simulator employing the database layout trace and the application execution trace to produce a simulation that yields results for analysis, the results being employed to analyze the execution of the application with the database;
• and
• (d) enabling another simulation of the execution of the application on another OODB selected from a plurality of different OODB, so that results are analyzed for comparison between the simulation on the OODB and the other simulation on the other OODB.

A system for simulating the execution of an application with an object oriented database management system (OODB), comprising:

• (a) a processor;
• and
• (b) a memory being coupled to the processor, the memory storing a plurality machine instructions that cause the processor to perform a plurality of logical steps when implemented by the processor, said logical steps including:
• (i) augmenting code comprising the application, producing augmented code, the augmented code including new instructions that enable the application to produce an application execution trace and a database layout trace when executed by the processor;
• (ii) executing the augmented code on the processor, with a database on the OODB, the execution of the augmented code producing the application execution trace and the database layout trace;
• and
• (iii) causing the processor to act as a simulator to simulate the execution of the application with the database on the OODB, the simulator employing the database layout trace and the application execution trace to produce a simulation that yields results for analysis, the results being employed to analyze the execution of the application with the database.
