    @KromStern The first section greatly glosses over how libraries work, and does so in a very unclear way with inconsistent use of code. I would contend that it doesn't really answer the question at all. The second section uses Java as an example (though trying to claim that the JRE should be considered part of the growth of the application size - which again misses the point of the question and isn't a fair example at all and continues to perpetuate the misunderstandings of Java). All in all it is either wrong, or repeats points in previous, better written, answers. Commented Sep 27, 2015 at 1:04

    Your example of logging to the network or file is not a good one either - because from the code's viewpoint, both are files and handled exactly the same way (the distinction between file and network is handled by the operating system). I have yet to see a logging framework that has "log to the database" as part of its core functionality as this would be complicated by Oracle vs MySQL vs Sql Server vs Postgres vs ... drivers and dialectical differences.

  • @user40980 The distinction between the file and the network is not handled by the operating system. They need different OS calls to connect to and write to. Database access is handled through a database independence layer like JDBC or libdbi. (Which in turn may pull in drivers for all the different supported databases!) Commented Jul 24, 2018 at 0:46
