Computational Independence Model (CIM) for Quering Multi-paradigm database

Abstract

The world of database has seen massive growth in terms of architecture, storage and query processing techniques. This advancement has led to a wide variety of datastores available in the market. Users and organizations choose the best datastore as per their business needs. However, the data available these days is quiteexcessively unstructured to be stored in a single database. This gave rise to the novel concept of Multi-paradigm database wherein we can store our data at in multiple formats (tabular, key-value, columnar or graphical). Construction of an efficient system for querying Multi Paradigm database is currently the need of many business applications. The complexity of system highly depends on the number of databases getting involved. The intent of this research is to present an efficient model that can query Multi-paradigm database using Model Driven Architecture. CIM i.e. the first footstepof MDA constitutes of preparing a low level model for the problem. The CIM diagram is formed as a result of requirement gathering activity. Questions like: “What this project needs to achieve?”, “Who are the different users and how they can be categorized?”,“What are the roles of these users in our project and how can they interact with each other?” are clearly answered by the CIM Model. These requirements not at all involve any implementation details or technology stack to be used. That is why they are generic and understandable by business stakeholders as well as the Developers. Better requirement gathering results in preventing issues such as scope creep and resource
