Conclusion

This article illustrates the steps needed use POSTGRESQL in applications:

• Issue a connection request and get a connection handle
• Issue a query and get a result handle
• Access the result

This article focuses on writing applications using only two programming languages. However, writing applications in other languages uses the same concepts. A chapter showing the same application written in various programming languages can be found in my book, PostgreSQL: Introduction and Concepts at http://www.postgresql.org/docs/awbook.html. More information about each programming interface is available in the PostgreSQL Programmer's Manual, http://developer.postgresql.org/docs/postgres/index.html. It covers the connection, query, and result functions specific to each interface.
