The comparision of relational database system and NoSQL database system's performances

It was very hard to process data in hierarchical and network databases up to aricle by Dr. Edgar Frank Codd in 1970, "Relational Model of Data for Large Shared Data Banks". Dr. Edgar Frank suggestion was as follows a table system, composed of rows and columns, namely relational database systems. Some major problems caused to develop relational database systems, also without any secondary applications people can not access to data. Moreover some complicated processes like pointers needed to be used to acess the data The increase in number of smart phones and the use of social media, text, image, video GPS and also sensor data the production of data reached petabytes and also some of the data produced is not in relational anymore. Main aim of this study is as follows : The comparison of perfomance of relational databases which is used almost 40 years, and NoSQL databases, namely Big data storage systems, with all advantages and disadvantages. This study aims to compare all advantages and disadvantages of relational DBMS with Big Data storage systems , namely NoSQL DBMS performances. Relation based DBMS, Document based DBMS and Column based DBMS performance compared with same size of data, this the main difference of this study from previous ones. As a result MongoDB DBMS perfomed well in read, write, update processes, for software developers dynamical schema creation is more adequate. MySQL DBMS perfomed well in delete and group processes. Cassandra DBMS perfomed well in record base processes which is done one by one, moreover in bulk processes unique field requirement caused poor perfomance.
