Difference between PostgreSQL and IBM DB2
1. PostgreSQL :
PostgreSQL is a powerful, open-source Object-relational database system. It provides good performance with low maintenance efforts because of its high stability. PostgreSQL was the first DBMS that implemented multi-version concurrency control (MVCC) feature.
2. IBM Db2 :
IBM Db2 is a family of data management products, including database servers, developed by IBM. It is a Relational Database Management System (RDBMS) which supports object-oriented features and non relational structure with XML. Db2 is designed to store, analyze and retrieve the data efficiently. It was initially released in 1983 and is written in C, C++, Java and Assembly language.
