MySQL vs PostgreSQL is a decision many must make when approaching open-source relational database management systems. Both are time-proven solutions that compete strongly with proprietary database software.

The long awaited 1.12 version of pgAdmin III is finally available. We will try to highlight some of the new features which have been added since the last stable release. Connection handling
In computer science , ACID ( Atomicity , Consistency , Isolation , Durability ) is a set of properties that guarantee that database transactions are processed reliably. In the context of databases , a single logical operation on the data is called a transaction.
