IBM DB2 : IBM DB2 is a database which has a relational model and is known for its performance. It has high scalability and is also known for its reliability. It is a commercial software and the main working principle of IBM DB2 is ACID. It was developed by IBM in the year 1983. The partitioning method which is used in IBM DB2 is sharding. It supports various query languages like SQL, JSON, XML, SPARQL etc. It is implemented in C and C++ language. IBM DB2 is widely used for storing huge amount of data and performing the transactions. 2. PostgreSQL : PostgreSQL is a database that has a object-relational model and was developed by PostgreSQL Global Development group in 1989. It is a powerful free open source software. It is also known as Postgres. PostgreSQL is supported by majority of operating systems and has a good performance. It is a extended version of SQL and has additional features. It mainly works on the principle of ACID. It is implemented in C language. Difference between IBM DB2 and PostgreSQL : S.NO. IBM DB2 PostgreSQL 1. IBM DB2 is a relational database model.
