Abstract

There exist a wide range of methods that can be used for the analysis and design of IT systems. However a survey of a wide range of methods and a detailed analysis of one structured method indicated the lack of a simple method for modeling hardware. The ORACLE database provides detailed guidelines regarding the minimum platform to run the database and how to derive table spaces (system, user, applications, rollback etc) size of shared pool buffer, Redo log buffer pool etc.that can be used to define hard disc capacity. The system can then be optimised. However little guidance is given regarding the performance of other devices (microprocessor, RAM, bus structures etc). This paper evaluates the new B-Node modeling technique as a possible standard technique in structured systems analysis and design for evaluating hardware performance.
