Обсуждение: PostgreSQL the right choice?
I have been looking for a RDBMS to deploy with our solar energy simulation. MySQL looks like it's free until you want to bundle it with a commercial application, at which time license fees are required. What is the situation with PostgreSQL? Given that we have a Java application and don't have the manpower to port a DBMS, what are the platforms on which PostgreSQL is currently stable? Is it possible to deploy PostgreSQL via an installer program, then automatically run a script to generate the tables and populate them with data from flat files? Thanks for any comments. -- Richard Chrenko, Informatik Institut für Solartechnik SPF Hochschule für Technik Rapperswil, Oberseestr.10, CH-8640 Rapperswil Tel +41 55 222 48 33, Fax +41 55 222 48 44, http://www.solarenergy.ch

I think the short answer is "all of them." It runs great on Windows (under cygwin) and many unix and linux. Try it out. Marshall

Mysql is a simple, fast database that is quite solid from my experience. It is usually my first choice as a web backend for php/jsp based websites. I usually use postgresql on system based projects (usually in perl ) where I really need to use foreign keys and tranactions and the loss of data would be a very expensive thing. The current version of mysql does have foreign keys and transactions available via the new innodb table type. I have not used it production yet, but I am testing them. -- Vincent Stoessel vincent@xaymaca.com Linux and Java Application Developer (301) 362-1750 AIM, MSN: xaymaca2020 , Yahoo Messenger: vks_jamaica

If your database is involved in a business, you need to migrate to PostgreSQL. One day or another, MySQL limited features will hinder you. /Jean-Michel

PostgreSQL is completely free for commercial and non-commercial use. pgAdmin2 (http://pgadmin.postgresql.org), PostgreSQL Windows administration interface is completely free. > Given that we have a Java application and don't have the manpower to > port a DBMS, what are the platforms on which PostgreSQL is currently > stable? PostgreSQL is the most stable Open-source database available. > Is it possible to deploy PostgreSQL via an installer program, then > automatically run a script to generate the tables and populate them with > data from flat files? Linux : PostgreSQL 7.2can be deployed via RPM (see PostgreSQL FTP in /binaries). Windows : PostgreSQL 7.2 is included in Cygwin installer (http://www.cygwin.com). An interactive doc is available from http://www.postgresql.org/idocs/. Cheers, Jean-Michel POURE
Do you really need an SQL Database for this? I am trying to figure out why you would need a database server with a simulation? I have heard of a tinySQL server that is written all in java and might do what you need without having to install and setup a database server just to run a simulation. How big is the data set you are using? couldn't you use a flat file for this? -----Original Message----- From: pgsql-general-owner@postgresql.org [mailto:pgsql-general-owner@postgresql.org]On Behalf Of Richard Chrenko Sent: Wednesday, March 13, 2002 1:55 AM To: pgsql-general@postgresql.org Subject: [GENERAL] PostgreSQL the right choice?

Checkout Firebird as well - which appears to be the other alternative.
http://firebird.sourceforge.net/index.php
q: How does open source affect the costs for companies which use
Interbase or Firebird as an embedded server?
a: Firebird server and client are free of all licensing fees,
regardless of whether you download a binary or build it yourself from
the source code.
I agree that mySQL is too limited for serious use.
