NoSQL Schema Extraction from Temporal Conceptual Model: A Case for Cassandra

NoSQL data stores have been proposed to handle the different breed of scale and challenges caused by Big Data. While a suitable schema design is of vital importance in NoSQL databases, in contrast to relational databases no standard schema design procedure exists yet. Instead, manual schema design is applied by using often vague and generic rules of thumb, which must be adapted to each application. Additionally, many applications require the management and processing of temporal data, for which NoSQL databases lack explicit support. To overcome such limitations, in this paper we propose an MDA-approach for mapping an existing conceptual UML class extension with temporal features into a NoSQL wide-column store schema. Then, we evaluate the schemas generated by our approach with the Cassandra wide-column store.
