Why each option
PostgreSQL and MySQL are both widely used open source relational database management systems (RDBMS) that use SQL and support ACID transactions.
PostgreSQL is a free, open source object-relational database system with decades of active development, known for standards compliance and extensibility.
NoSQL is not a database product but a category describing non-relational databases that do not primarily use SQL or a tabular schema.
MySQL is a free, open source relational database management system owned by Oracle, and is one of the most widely deployed databases in web applications worldwide.
DB/2 (IBM Db2) is a proprietary relational database product from IBM, not an open source system.
MongoDB is an open source database, but it is a document-oriented NoSQL database, not a relational database system.
