I did a search for a freeware cataloging software and found this French guy Alain. He created a nice collection software which come with a build in Paradox database. Don't worry about the database. It will self create for you during the installation.
I downloaded the software and tested it. Seem to be a flexible and simple software to use with all the basic requirement of creation, modification and view screens. In addition, it has a search feature which uses the industry standard SQL. SQL is a structured query language which retrieve data according to your required conditions ( select all those with country = "Singapore" ). In any case, it has a help screen to assist you when you are using the software. There are also other useful features such as Importing and Exporting to and from Excel, HTML and ASCII. There is also a backup for your data as well.
The author makes an effort to add in new features. The last updated was on Jan 2007 which was relatively recent. The software is known as Happy Collection Version 2.5. I am sure you will be happy with it. It's a freeware.
You can download it at

While testing the software, I have capture the screen for you. I have created the database fields based on my requirement. You can choose to create your own fields under the database creation screen which is located on the top bar menu.
If you have any questions, you can ask me. I should be able to answer you even though I have not written the program for this software.
Happy Collecting !
