@article{(Open Science Index):https://publications.waset.org/pdf/2212, title = {A Formal Suite of Object Relational Database Metrics}, author = {Justus S and K Iyakutti}, country = {}, institution = {}, abstract = {Object Relational Databases (ORDB) are complex in nature than traditional relational databases because they combine the characteristics of both object oriented concepts and relational features of conventional databases. Design of an ORDB demands efficient and quality schema considering the structural, functional and componential traits. This internal quality of the schema is assured by metrics that measure the relevant attributes. This is extended to substantiate the understandability, usability and reliability of the schema, thus assuring external quality of the schema. This work institutes a formalization of ORDB metrics; metric definition, evaluation methodology and the calibration of the metric. Three ORDB schemas were used to conduct the evaluation and the formalization of the metrics. The metrics are calibrated using content and criteria related validity based on the measurability, consistency and reliability of the metrics. Nominal and summative scales are derived based on the evaluated metric values and are standardized. Future works pertaining to ORDB metrics forms the concluding note.}, journal = {International Journal of Computer and Information Engineering}, volume = {2}, number = {12}, year = {2008}, pages = {4177 - 4186}, ee = {https://publications.waset.org/pdf/2212}, url = {https://publications.waset.org/vol/24}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 24, 2008}, }
