The first answer is a good answer. I would add the following advice: If you have to ask which database to use, your knowlege of databases is not sufficient to use one without a significant learning curve. I believe you are more interested in organizing data than learning to use a real database.
A spreadsheet is the easiest way to do that. If you do not have Excel and do not want to buy it, take a look at Sun Open Office. It includes a word processor and a spreadsheet that are compatible with Microsoft Office documents.
AND, it is free. I use it every day. openoffice.org/ At some point in the future you could add a MySQL database to your web site and let your users do searches for themselves.
The data record for each plan could include a link to a graphic file containing a floor plan ( with limited detail, you obviously don't want to post a useable plan for download. ).
Many people use Excel for simple databases. To know whether Excel would be sufficient, or you need something more complicated, I'd need to know how much data you need to store, what that data would be, and how exactly you'd need to access and update it. However, from what you've said there is a good chance Excel would do the job for you.
Some intros on how to get started with using Excel for creating databases are here: spreadsheets.about.com/od/datamanagement... und.nodak.edu/dept/cndtrain/Excel/databa... Another advantage of giving Excel a try first is that most database systems will happily import Excel data, if you do need something a bit more fancy later on.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
