I just wondered and start reading SQLite source code.
There weren't any fopen,fclose except logging functions.
I tried to track down sqlite3_open, sqlite3_prepare, I came into sqlite3parse and stuck.
There is fopen in
sqlite3MemdebugDump
sqlite3Memsys3Dump
sqlite3Memsys5Dump
sqlite3VdbeTransferError
which are debug functions.
Are they wrote their own disk handler?
(I always stunned how professional applications handle this kind of things.)
Summary: How SQLite handle files without fopen?
SQLite accesses files through its OS interface, which is implemented in the os_*.c files.

why is there not a url such as :
https://console.firebase.google.com/u/0/project/axel-02/database/firestore/data~2Fusers
but for local developement. It would be for example :
https://localhost:9000/console.firebase.google.com/u/0/project/axel-02/database/firestore/data~2Fusers
I mean, the data viewer is usefull... but it s a pain that it does work with the emulator in local dev.
You can use the following third-party tool: https://github.com/ablehq/firestore-explorer.
The emulator suite is a pretty recent release, and there's a long list of features that would make it more useful.
If you think the product would benefit from having such an explorer built in, file a feature request with Firebase support or on the Github repo of the project.

I have an app in which the user should be able to store videos. I was wondering if Firebase or Sqlite would be better for the job. Please get back to me as soon as possible.
Unless the videos were really short then you wouldn't store them in a database. You would store them as files and store the path to the file in the database.
SQLite would be better if the data in the database is device specific and thus needed no syncing with other devices.
Firebase could be the choice if syncing the data across devices.

As you know when if a stranger know the path of your SQLite database file he can easy download it. my question is how to avoid that?
I'm assuming you're accessing the SQLite database server-side. You could configure whatever host you're using (apache, nginx, etc...) to not allow access to the file or you could change the permissions to the file to only allow you to view it (using chmod).

In relation to Teradata Client 14.10, I was wondering if I could use this tool to run SQL, view tables and change passwords?
New to teradata.
Many Thanks.
Use the SQL Assistant from the client set, it would suffice.
Studio is too cranky at this point, was supposed to be an equivalent eventually replacing the assistant.
... teradata studio; a pre-baked eclipse plugin. Works pretty well and doesn't require all the old men ODBC configuration '90s msft weirdness. sorry a 'lil high rugh now.
