    The programmer’s wife tells him: “Run to the store and pick up a loaf of bread. If they have eggs, get a dozen.”
    The programmer comes home with 12 loaves of bread.

    I still think the three categories may be what I described. I may not have used exactly the right words, but say 20-30 years ago, a database system was something you couldn't use a PC to access [other than as a PC terminal application accessing a minicomputer or mainframe].

    This then progressed into client/server solutions, where a central database is partially processed locally on the client, whilst the data is stored in one central point.

    The next extension to that is a distributed database, where data is held in various locations - either that some data is in one place and some data in another place, or that all the data is available in multiple places - just pick the nearest.

    Yes, there are many ways you can make up the hardware/software solutions for a database. But I don't think that is what the question is about.

    I interpreted the question as "how has databases processing changed over time".

    Mike_G: Does any of this make any sense in relation to what you have been learning in class? If not, perhaps you need to get some clarification from your teacher.

    Nah, I have no idea. All we do in class is make up SQL queries. We havent done any history of databases or anything. Guess I should really go find out what they expect from me.

    You all seem to make good points; its just a matter of how you interpret the sentence.

    Yes, and as we all know, even the simplest sentences can be misunderstood sometimes. In this case, it's quite possible that all of the suggestions are wrong, or that one or another of the alternatives is right.

    Simple solution: email your professor and ask him how the question should be interpreted.
