Document Database Design Using ORM Conceptual Data Model

Abstract

Unstructured data is the most common type of data generated on a daily. Businesses must discover ways to retain such data to analyze and use it to make business choices. Document databases have emerged to the needs of applications. This database has a schemaless feature that allows for more flexibility in data management. Particularly, a document database does not define conceptual modeling. The conceptual data model is one of the essential phases in database development. The original data model makes it difficult to express queries on document databases. Therefore, developers need the conceptual model to understand business users and related data. This work provided a standard design strategy for document representation. ORM is utilized in this approach for conceptual modeling adopted through a document model. This paper defined a set of graphical symbols to document database concepts such as collection and two kinds of relationships. Furthermore, the current challenges in document database modeling were highlighted throughout the discussion of this topic.
