Some researchers proposed mechanisms for the co-existence of No SQL and Relational databases together. This paper provides a literature review of some of the recent approaches proposed by various researchers to migrate data from relational to No SQL databases.
Various frameworks has been proposed previously which provides mechanisms for migration of data stored at warehouses in SQL, middle layer solutions which can provide facility of data to be stored in No SQL databases to handle data which is not structured. Relational database provides the easiest way to manage the data but as the use of No SQL is increasing it is becoming necessary to migrate the data from Relational to No SQL databases. Relational databases are only able to deal with structured data, so there is need of No SQL Database management System which can deal with semi -structured data also. Data is very precious component of any application and needs to be analysed after arranging it in some structure. Ghotiya, Sunita Mandal, Juhi Kandasamy, Saravanakumarĭata generated by various real time applications, social networking sites and sensor devices is of very huge amount and unstructured, which makes it difficult for Relational database management systems to handle the data. Migration from relational to No SQL database Der Vortrag zeigt erweiterte Funktionen von Postgre SQL wie Views, Rules, Stored Procedures und Trigger sowie deren Verwendung in der CSN Datenbank. Das Chemnitzer Studentennetz benutzt seit 1999 Postgre SQL zur Verwaltung seines Netzes. Postgre SQL ist eine Open Source Datenbank, die in den letzten Jahren sehr populär geworden ist. Expert author Shashank Tiwari begins with a helpful introduction on the subject of No SQL, explains its characteristics and typical uses, and looks at whereĮin Elefant vergißt nicht - Erweiterte Funktionen in Postgre SQL am Beispiel der CSN Datenbank This comprehensive hands-on guide presents fundamental concepts and practical solutions for getting you ready to use No SQL databases. In addition, they are often malleable and flexible enough to accommodate semi-structured and sparse data sets. Most No SQL databases scale well as data grows.

The result of this work can provide some guideline for choosing an appropriate RDF database system and applying a No SQL database in storing and querying RDF data. However, for a larger data set, MongoDB performs well for queries with simple operators while My SQL offers an efficient solution for complex queries. Based on the experimental results analysis, our proposed system outperforms other database systems for most queries when the data set size is small. We compare three database systems, which are Apache Jena TDB (native RDF store, My SQL (relational database, and our proposed system with MongoDB (No SQL database. We evaluate the proposed design and implementation by using the Berlin SPARQL Benchmark, which is one of the most widely accepted benchmarks for comparing the performance of RDF storage systems.
We choose MongoDB to represent a No SQL database because it is one of the most popular high-performance No SQL databases. In this paper, we propose a method to exploit a No SQL database, specifically MongoDB, to store and query RDF data. Resource Description Framework (RDF is a standard for describing web resources. This causes the need for Semantic Web technology to quickly analyze such big data. Its metadata is widely used in order to fully exploit web information resources.
