Relational database and graph database: A comparative analysis [PDF]
Journal of Process Management. New Technologies, 2017 Since 1970, relational database models have been in use for storing, manipulating and retrieving data. The importance of relational databases is going to decrease due to the exponential growth of data as it is difficult to work with large number of joining tables.

A Comprehensive Spark-Based Layer for Converting Relational Databases to NoSQL
Big Data and Cognitive Computing, 2022 Currently, the continuous massive growth in the size, variety, and velocity of data is defined as big data. Relational databases have a limited ability to work with big data.

Set-oriented data mining in relational databases [PDF]
, 1995 Data mining is an important real-life application for businesses. It is critical to find efficient ways of mining large data sets. In order to benefit from the experience with relational databases, a set-oriented approach to mining data is needed.

Database relations with null values [PDF]
Journal of Computer and System Sciences, 1982 A new formalism for null values is developed, based on the semantics that a null value conveys no information; that it is less informative then either an ''exists but unknown'' or a ''no value'' null. What results is a theory of ''heterogeneous relations'': relations with tuples over different schemes.

Preferences in Temporal Relational Databases
IEEE AccessDespite the huge amount of work devoted to the treatment of time within the relational context, some relevant phenomena remain to be fully addressed. We focus on one of them, i.e., temporal indeterminacy with preferences.

Translation of Relational and Non-relational Databases into RDF with xR2RML
International Conference on Web Information Systems and Technologies, 2015 With the growing amount of data being continuously produced, it is crucial to come up with solutions to expose data from ever more heterogeneous databases (e.g. NoSQL systems) as linked data.
