. Relational databases create more problems when dealing with these trends. This leads to the emergence of a large number of different techniques to address specific aspects of these problems, which can interact with or replace existing RDBMS-also known as hybrid persistence (Polyglot persistence). Database substitutes are not new, they have been in the form of object Databases (OODBMS), hierarchical databases (such as LDAP) for a long time. However, over the past few years, a number of new
