| Abstract | The polyglot persistence refers to the use of several DBMS with different data models in the same application. One of the motivations for the use of polyglot persistence comes from the growing amount of data of any types (structured, semistructured and unstructured) that are handled in applications such as: social networking, e-commerce, mobile applications. NoSQL DBMS represent a set of non-relational database systems of high performance designed to handle vast volumes of data, besides allowing the storage of semi-structured and unstructured data. Several researches propose conceptual models to support the design of NoSQL databases. However, no proposal that addresses the conceptual data design of polyglot persistence applications was found in the literature. Therefore, this work specifies a conceptual data model, called ERNoSQL, that extends the Entity-Relationship model by adding specific constructors to enable the modeling of DB applications with polyglot persistence. To provide an overview of the proposed conceptual model, a meta-model that provides an understanding of how ERNoSQL constructors are related was specified in UML. The work also specifies a set of mapping rules of the ERNoSQL model for the logical structures of the NoSQL models (documents, graphs, key-value and family of columns). To support the activities of modeling polyglot schemes, this paper also proposes a CASE tool for the construction of conceptual data schemas from the ERNoSQL modeling constructors. The tool, called NoSQLCASE, has a graphical environment for constructing the conceptual schema that provides export functionality for scripts expressed in NoSQL DBMS languages. Finally, a case study was conducted to compare conceptual data schemas constructed by two existing CASE tools that are based on the ER model and conceptual schemas of data designed by the proposed NoSQLCASE tool. In addition, the export functionality of NoSQLCASE was illustrated by the implementation of scripts generated by the proposed tool in the MongoDB DBMS. |
