Works suites were a big earner for decades. MS Works started out on DOS and moved to Windows. Its database was arguably superior for simple stuff to anything out of MS for Windows.
Novell had a Works suite too, and Apple.
And there were several independent ones, such as PFS Works, Beagle Works and others. Also more primitive suits where one app has multiple functions, such as Pipedream and the original Lotus Symphony.
Most were single monolithic apps under the UI. LibreOffice still is. Data interchange was significantly easier than in standalone apps.
