RDBMS PostgreSQL
RDBMS stands for Relational Database Management System. RDBMS is the basis for SQL, and for all modern database systems like MS SQL Server, IBM DB2, Oracle, MySQL, PostgreSQL and Microsoft Access. In this series we are handling with PostgreSQL database.
The data in an RDBMS is stored in database objects which are called as tables. A table is a collection of related data entries and contains rows and columns to store data.
A field is a column in a table that maintains specific information about every record in the table. A row of table is called record. It contains the specific information of each individual entry in the table. A column is a vertical entity in the table which contains all information associated with a specific field in a table.
PostgreSQL is a powerful, open source relational database system. It runs on all major operating systems, including Linux, Windows and Mac OS. It supports most SQL data types, foreign keys, joins, views, triggers and stored procedures.. It has programming interfaces for C/C++, Java, Perl, Python, Ruby etc.
