Abstract
A system and a method is disclosed for analyzing, benchmarking and tuning an object oriented database (OODB) and applications with a trace based technique. Code associated with the application is augmented with a plurality of instructions that define the production of an application execution trace and a database layout trace during execution of the application with a database. A precompiler or manual or automatic techniques are used to augment source code associated with the application. Alternatively, an instrumentor can be employed to augment object code associated with the application. A simulator employs the database layout trace and the application execution trace to simulate the execution of the application with an OODB selected by the user. The simulator may be ported to different OODBs or platforms. The simulator produces results associated with the simulation for input to a data analyzer. The data analyzer includes a user interface that enables a user to modify the simulation and can display the analysis of the simulation in real time. In another preferred embodiment, the present invention is employed with a distributed object oriented system that is implemented on multiple computers communicating by a network.
