Postgre SQL server is an open source database server. The postgre SQL system is open source and is supported by almost all the operating systems. To begin with, this database system is more robust than the normal Mysql database system. Adding to its flexibility and robustness, it has got a lot of added features which makes It widely used. This DB system is not only complies with the ACID properties but also supports foreign keys, views, joins, triggers and stored procedures. Other than Boolean data, this DB is capable of storing large binary objects, including video, pictures and sound. It provides programming interfaces with almost all the major programming languages like c/c++, java, perl, ruby, python, .Net,etc.
With high data integrity and concurrency, it has got a lot of advanced and sophisticated features. Some of the added advanced features are tablespaces, point in time recovery, nested transactions, asynchronous replication, sophisticated query optimizer, hot backups, and write ahead logging for fault tolerance. The robustness of postgre SQL comes from its high scalability both in terms of concurrent users and quantity of data that it is capable of managing. There are a lot of postgre SQL servers which manage terabytes of data.
Complying with standards and full of features, it conforms to the ANSI-SQL: 2008 standard. The integrity of this DB has features like cascading foreign keys, compound primary keys, unique, null and checks constraints, etc. A lot of content management systems need a very robust Data Base in the back end to store its contents. These CMS’s are dependent on robust data base servers like postgre SQL server and maridDB server. The generalized search tree functionality allows one to search and sort a postgre data base using algorithms like B-tree, R tree, B+ tree and many more. The searching and sorting techniques can be customized by the user.Tags:
