I have a database of client information, which is quite valuable to us. My business is going to be using an out of office third-party who will need to use this database. Currently we have it just stored in Excel - so we don't want to just hand it over to them in this format since they can easily copy it. I've worked with Microsoft Access in the past and know that I can at least make it a bit difficult for them to entirely copy the database - and to make it at least secure. Are there any good database programs I should be looking at? Hopefully there's something really simple that I can just build a template and feed in the CSV file. It would be also ideal if the database can be exported onto the web, so the database isn't physically on their machine. Does anyone have any suggestions?
