Storage Systems for Big Data Internet age comes with the vast amount of data that requires efficient storage and processing capabilities. To alleviate this issue, we discuss data storage systems which are tailored to store and process big data effectively. While general-purpose RDBMSs are still viable option in handling and analyzing structural data, they suffer from a variety of problems including performance and scalability issues when it comes to big data. To increase the performance of DBMS…

Besides, I searched about “Relational Databases” because most databases are relational database, and they store their data in relation. 2. I…

The Relational Database Framework The collection of information provides access to the network of the data-processing system. The representation consists vital information of real-time events. The objective requires managing personal cognizant comportment for integrating vital information. The standard utilizer and application (APP) program interface to a relational database is the Structured Query Language (SQL) (Codd, 2003-2016). The APP retrieves and supplies the information from the graph…
