Changes

== Introduction ==__NOEDITSECTION__

{{IMSMANG}} version 6.0 is building on a PostgreSQL database management system, whereas previous {{IMSMANG}} versions were built on a MySQL database. Both systems are relational database systems and using SQL, the Structured Query Language, as means for interacting with it. However, there are some differences between the MySQL and PosrgreSQL syntax. It is not possible to list all differences here, but the main ones encountered in the {{IMSMANG}} world are highlighted below.
