Most NoSQL databases have been devised independently from each other with specific application requirements. This has resulted in developing separate own data model and query language for each NoSQL database. The lack of standards in data models and query languages make applications and data less portable using these databases. Further, absence of formal semantics in query languages inhibits a precise...
QoS evaluation based on their historical data not only helps in getting more accurate QoS, but also helps in making future QoS prediction, recommendation and knowledge discovery. [1] designed a generic QaaS (Quality as a service) model in the same line as PaaS and SaaS, where users can provide QoS attributes as inputs and the model returns services satisfying the user's QoS. It uses historical data...
Now-a-days with the enormous synthesize and increasing use in the arena of cloud computing, smart devices, and business intelligence, Big Data also has become a growing area of research. Yet in literature existing approaches regarding logical level designing of Big Data is very rare. Most are about representation of both semi-structured and structured data and from the perspective of schema-base....
Proper modeling concepts are essential towards the effective design of XML based Data Warehouse (DW) system in presence of semi-structured multidimensional data. From the methodological point of view, such model should facilitate the representation of multidimensional XML data and the associated structures in order to perform OLAP in XML based DW. Thus a systematic transformation mechanism is essential...
This paper has proposed a case study of insurance industry through implementing the Graph — semantic based conceptual model for semi-structured database system, called GOOSSDM. The GOOSSDM reveals a set of concepts to the conceptual level design phase of semi-structured database system, which are understandable to the users, independent of implementation issues and provide a set of graphical constructs...
This paper has proposed a Graph — semantic based conceptual data model for XML based Data Warehouse (DW) system called GXDW model, to conceptualize the different facets of multidimensional databases which may contain semi-structured data. The model is an extension of object oriented paradigm and defines a set of graph based formal constructs, variety of relationship types with participation constraints...
