Schema profiling of document-oriented databases [PDF]
Information Systems, 2018 Abstract In document-oriented databases, schema is a soft concept and the documents in a collection can be stored using different local schemata. This gives designers and implementers augmented flexibility; however, it requires an extra effort to understand the rules that drove the use of alternative schemata when sets of documents with different ...

Implementation of Multidimensional Databases with Document-Oriented NoSQL [PDF]
Lecture Notes in Computer Science, 2015 NoSQL (Not Only SQL) systems are becoming popular due to known advantages such as horizontal scalability and elasticity. In this paper, we study the implementation of data warehouses with document-oriented NoSQL systems. We propose mapping rules that transform the multidimensional data model to logical document-oriented models.

Approximate OLAP of document-oriented databases: A variety-aware approach [PDF]
Information Systems, 2019 Abstract Schemaless databases, and document-oriented databases in particular, are preferred to relational ones for storing heterogeneous data with variable schemas and structural forms. However, the absence of a unique schema adds complexity to analytical applications, in which a single analysis often involves large sets of data with different ...

Design a Data Warehouse Schema from Document-Oriented database
Procedia Computer Science, 2019 Abstract Traditional data warehouses are unable to meet the growing needs of the modern enterprise to integrate and analyze a wide variety of data generated by social, mobile and sensor sources. What is remarkable is that many companies have changed their data storage in NoSQL databases.
