Graph Database: Comparative Study of RDBMS Versus NoSQL
摘要
The Relational Database was widely used in Industry and academics for software development in the early 90’s and it is continuing now even starting from Oracle 7.1.3 version. But with increasing complexity of data, unstructured data or semi structured data capturing, research has shifted the paradigm from SQL to NoSql. Variety of NoSql databases has emerged and could not sustain in the market because of their own limitations. The Relational Database System has complex join operation and is costly compared to NoSql. 80% market share is grabbed by Oracle for any new software development in 2005 and later on researcher started inventing NoSql with low cost, open source and it’s quite challenging. In our IEEE 2020 we did survey different types of Graph databases and also showd the path on how to re-engineer SQL to NoSql in the Springer publication. This paper aims to provide insights about Nosql MongoDB, relational database Oracle or MySQL, re-engineering methodologies study from sql to NoSql and also how much faster is SQL vs. NoSql.
