The first research in the literature review is carried out by Wasserman et al who characterizes the technique to manage the BI workload. The technique is based on the resource related attributes such as CPU usage, sequential & random I/O rate, join degree. The workload characterization is performed by following the following steps.
1. Components identification
2. Selection of the characterizing parameters
3. Input data normalization
4. Workload grouping into classes
5. Finally, identification of each class
However, the technique works by taking the mostly parameter¡¯s value on the basis of assumptions.
