PostgreSQL is an open-source, object-relational database management system (ORDBMS) that is not owned or controlled by one company or individual. Because PostgreSQL software is open-source, it is managed mostly through a coordinated online effort by an active global community of developers, enthusiasts, and other volunteers.

An enterprise class database, PostgreSQL boasts sophisticated features such as Multi-Version Concurrency Control (MVCC), point in time recovery, tablespaces, asynchronous replication, nested transactions (savepoints), online/hot backups, a sophisticated query planner/optimizer, and write ahead logging for fault tolerance.

PostgreSQL supports international character sets, multibyte character encodings, Unicode, and it is locale-aware for sorting, case-sensitivity, and formatting. It is highly scalable both in the sheer quantity of data it can manage and in the number of concurrent users it can accommodate. There are active PostgreSQL instances in production environments that manage many terabytes of data, as well as clusters managing petabytes

HTTP is a protocol that works with a client / server architecture. The client makes a request, and the server returns the response. In common use, the client corresponds to the browser and server the machine on which the website resides. There are therefore, two types of HTTP messages: request messages and reply messages.

HTTP differs from other layers seven protocol such as FTP, because connections are generally closed once a particular request (or a series of related requests) has been met.

This behavior makes the HTTP protocol ideal for the World Wide Web, where the pages very often contain links to pages hosted by other servers thus decreasing the number of active connections limiting them to those actually needed with an increase in efficiency (lower load and occupancy) both on the client and on the server. However, sometimes it poses problems for web content developers, because the stateless nature of the browsing session forces to use alternative methods (typically based on cookies) to preserve the user's status.
