This is a tricky one. I feel like I know the general differences between file-based and relational databases, but putting them into a specific list of three characteristics is challenging. I'll review my notes and try to eliminate the options that don't seem quite right.
Okay, let me see if I can break this down. File-based systems don't have the same level of data independence and structure as relational databases, so I'm guessing the answer has to do with things like data repetition and dependence. I'll make my best guess and hope for the best!
Hmm, I'm a bit confused on this one. I know file-based systems have some differences from relational databases, but I'm not sure I can recall the specific characteristics they're looking for. I'll need to think this through carefully.
I think this question is pretty straightforward. The key is to identify the characteristics of file-based database systems, which are typically things like data repetition, application program flexibility, and data centralization.
You know, they should just call it the 'Jurassic Park' database, because it's as outdated as the dinosaurs. But hey, at least it's not as buggy as their systems, right?
User 2: I disagree, I'm going with B. Incompatibility of files, tabular data structures, and data dependence make more sense for a file-based database.
Option C seems to hit the nail on the head. Separation of data, repetition of data, and data independence - that's the essence of a file-based database system, isn't it?
