Abstract:
Introduction: Nowadays, NoSQL databases have taken on an increasingly important
role in the storage of massive data within companies. Due to a common property called
schema-less, NoSQL databases offer great flexibility, particularly for the storage of data in different
formats. However, despite their success in data storage, schema-less databases are a major
obstacle in areas requiring precise knowledge of this schema, especially in the field of data
integration.
Method: This study presents a Systematic Literature Review (SLR) to explore, evaluate, and
discuss relevant existing research and endeavors using novel schema extraction approaches.
Furthermore, we conducted this study using a well-defined methodology to examine and study
the problem of schema extraction from NoSQL databases.
Results: Our research results highlight and emphasize the scheme extraction approaches and
provide knowledge to researchers and practitioners by proposing schema extraction approaches
and their limitations, which contributes to inventing new, more efficient approaches.
Conclusion: In our future work, inspired by the recent advances in quantum computing and the
emergence of post-quantum cryptography (PQC), we aim to propose a schema extraction approach
that blends cutting-edge technologies with a strong focus on database security.
