  •  I've done both legacy back-end (4+ / 0-)

    mainframes and front-end Windows and web, and I agree. Don't forget that a lot of "back-end database" is often accomplished by calling legacy COBOL programs to retrieve data from VSAM files on the "database" may not even be a database. In addition, during my experience in government IT many years ago, there WEREN'T the "off-the-shelf" solutions yet, so every department wrote their own programs, using their own standards. Coordinating that all into a new huge system must have been a nightmare.

    Some of the mainframe stuff may have been updated into true databases (IBM mainframe is usually DB2), but if it ain't broke, you usually don't fix it, because it's too expensive.
