Comparison between Relational and NoSQL Databases [PDF]
Relational databases have not been the only solution for the applications that use them for years. New applications must deal with large volumes of complex, distributed data of different types, whose volume increases very rapidly.

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene
Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

CLASSIFICATION OF LOGICAL DATA MODELS IMPLEMENTED BY CONTEMPORARY DBMS
Apart from relational model, many contemporary DBMS implement different data models, including extensions of relational ones. Most of DBMS implement also multiple data models, and are so called “multi-model”.
