java - Database Schema -


if have file/folder , want have different users able access it... i.e folder 1 can accessed j, k , m....

should file/folder have own table list of users can access it, or should each user have list of files/folders can access.

i want bare in mind extensibility when comes database. cant see best thing do.

in database, same space: imagine 1million folders 3 person: @ maximum: 1million / person or 3person / million equals 3millions in db. if have in mind extensibility, think of you're going add most, folders or people. if you're adding lot of folders, it's easier put people can access folder attached folder, if you're adding lot of people, it's better have folder person can access attach person when create new folder/person can directly give him rights/persons.

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
