It is a small download and installation is a very easy. It actually makes Java a bit more pleasing.

Some quick uses I've found so far include:

  1. Making quick test scripts to integrate different Java components.
  2. Adding such scripts write into an Ant task.
  3. Using the great pprint and dir functions to dive into Java classes and methods much faster than API documentation.

I am sure there are many more ways Jython can be used. For example, I checked in one old script that took about 15 minutes to write -- it provides a rudimentary interactive sql shell. The code couldn't be simpler! A while back, I needed to access an Oracle database. SQL*Plus was not installed in the client machine and the installer was not available either. This script came in handy then.

If you're a database specialist interested in growing your DB2 Universal Database skills, there's a good chance that you've already developed database skills with another relational database product somewhere along the way. This article shows you how to use your current knowledge of Oracle 9i to quickly gain skills in DB2 UDB for Linux, UNIX, and Windows Version 8.

Comparing to Java and eXtreme Programming as the fashionable tools, the main reasons cited where:

It doesn't have to be - you get reliability, maturity and familiarity with your data, using SQL. 915@http://vsbabu.org/mt/ Jack D.

Today, I tried using Jython. It is as easy as using CPython.

I really liked zxJDBC. Especially the dbexts wrapper - makes it much easier to write portable code by moving DB parameters to a configuration file.

In this article, I'll explain how to get started using it on Windows. Warning: extremely short instructions. 798@http://vsbabu.org/mt/ Why Firebird?
  • Tiny download and install - 2.6MB
  • Quite mature
  • Good feature set like stored procedures. SQL is similar to that of Oracle and PostgreSQL.
  • Free!

More information can be had from the novice guide.

Notes on setting up this combination on a fast-to-use Linux system. 766@http://vsbabu.org/mt/ After I got MySQL configured and loaded with data on my Mandrake 9.1, I wanted to see how to access it from Python. Turns out to be pretty easy. In this article, I'll explain how to configure MySQL driver for Python, and a small self-explanatory Python script explaining data access.

Quick notes on setting up Python to access PostgreSQL. 765@http://vsbabu.org/mt/ This is a followup article to Sunday's experiment on accessing PostgreSQL from Java. I quickly got tired of typing in all the curly braces, save-compile cycle with Java. In this article, I will try to explain how to get started with accessing data in our PostgreSQL from Python. Installing Python, necessary drivers and writing a small Python program are covered.

Really fast. 764@http://vsbabu.org/mt/ After trying out PostgreSQL for loading web server logs, I decided to see how MySQL would fare. PostgreSQL has lot more options, especially foreign keys, stored procedures, triggers, much more standard SQL and more functions. But the default installation turned out to be slightly slower in executing my queries. MySQL is known for its speed, atleast for few-writes-many-reads kind of usage. Here are my notes on getting started with MySQL on Mandrake 9.1. I've not covered issues like security, fine tuning or backup and restore.

I will try to explain how to get started with accessing data in our PostgreSQL from Java. Installing Java, necessary drivers and writing a small Java program are covered.

If you are in a big hurry to get PostgreSQL going in your shiny new Mandrake Linux 9.1 machine, here is how to do it quickly.

These notes don't address security or backup and restore. I explain how to start the database server, create a user and database, create a table in the database, add some data and query it back.

It facilitates the browsing of tables, columns, rows, functions, languages, sequences, and other database objects through any webdav enabled client.

I agree, this is a *really* cool idea. Obviously cool enough to generate several random thoughts.
