Abstract

The NoSQL systems make it possible to manage Databases (DB) verifying the 3Vs: Volume, Variety and Velocity. Most of these systems are characterized by the property schemaless which means absence of the data schema when creating a DB. This property provides undeniable flexibility by allowing the schema to evolve while the DB is in use; however, it is a major obstacle for developers and decision makers. Indeed, the expression of queries (SQL type) requires precise knowledge of this schema. In this article, we provide a process for automatically extracting the schema from a NoSQL document-oriented DB. To do this, we use the MDA (Model Driven Architecture). From a NoSQL DB, we propose transformation rules to generate the schema. An experiment of the extraction process was carried out on a medical application.
