I would assume it was a relational database.. I also assume you mean the fingerprint database that is used by the police forces. as far as i am aware it is a relational database. I think because you could query either a name or a fingerprint reading and then get the information relating to it..Example: If you were looking for the name to a set of fingerprints, you would enter the finger print into your query, and then you might get a name if it is in the database, and if you were looking for the fingerprints to a guy, you would enter a name and you might get the fingerprints for him if you have the right name and it is contained within the database.
To find a person by photo only, you can try showing the photo to other people who might know this person. The police can use image matching software to find a person by photo, but the person must already be in a database.
why would you use database?
You could use the string replace attribute but you might have to use Javascript, CGI, ASP or another scripting language to do so.
