Robin Bloor examines the evolution of relationaldatabase and object oriented technology , and proposes a solution which overcomes the terminal points of these two technological developmentsContents of Bloor s in briefWhile discussing `relational database , Bloor mentions that one of the foundations ofrelational theory is that the data and the program that uses it should be supreme ofeach other . This was and is at odds with the whole inclination of object technology . He givesthe example of a car taken as an object , and refutes the idea of data and its associatedprocesses universe supreme of each other . He strongly ad vocates that data and itsassociated processes cannot be and should not be separatedBloor cites one more limitation of relational database . He says that , comparativedatabases are more constrained in their capabilities than most(prenominal) would suspect . Storing andrepresenting some fairly common data structures , can be very difficult . He takes theexample of a simple ed numerate of bus stops . Relational databases entirely hold tables asuned lists and can retrieve an ed list only(prenominal) if a specially built index is addedAn object database does not need index`Performance overhead is another(prenominal) concern of Bloor . He says that , in relationaldatabase , to assemble data , developers have to JOIN one table to another...If you want to get a full essay, locate it on our website:
