Many moons ago, when I was just a whipper-snapper of a coder, I was employed to write a DOS based accountancy package. Part of the brief was to develop a fast DB back-end that could support cross searching of all financial information recorded. Without a ready-to-roll DB engine, I ended up developing a complete set of DB modules, with extensive use of linked lists to tie the records together, and raw binary read/writes in/out of the DB file. End result is I still know way too much about DB design than I'd ever care to want to, and have very little patience for unwieldy DB interfaces.
