Waarom ik nooit opruimde#Eerlijk? Omdat ik het niet meer overzag.Als je één map hebt met rommel, ruim je die op. Maar als je tien mappen hebt, op zes verschillende plekken, met allemaal dezelfde soort inhoud - waar begin je dan? Welke is de “echte”? En wat als je per ongeluk iets weggooit dat je nog nodig had?Dus startte ik iedere keer dapper met opruimen. En stopte dan weer net zo snel.

Interaction with stable storage in the modern world isgenerally mediated by systems that fall roughly into oneof two categories: a filesystem or a database. Databasesassume as much as they can about the structure of thedata they store. The type of any given piece of datais known (e.g., an integer, an identifier, text, etc.), andthe relationships between data are well defined. Thedatabase is the all-knowing and exclusive arbiter of ac-cess to data.Unfortunately, if the user of the data wants more di-rect control over the data, a database is ill-suited. At thesame time, it is unwieldy to interact directly with stablestorage, so something light-weight in between a databaseand raw storage is needed. Filesystems have traditionallyplayed this role. They present a simple container abstrac-tion for data (a file) that is opaque to the system, and theyallow a simple organizational structure for those contain-ers (a hierarchical directory structure)
