MyDB

I have no clue how databases work It has been so long since my DB course, all I know is that they use B-Trees to store data I'm gonna attempt to write my own DB anyway

File format

Train of thought

As far as I'm concerned, the most important thing is probably the way the database gets stored. I don't want it to be in memory so I will have to create a file (or more) on the filesystem in which all the data is going to be stored. As far as I know, sqlite stores databases in a single file, I'm not sure about others like postgresql, mysql/mariadb, oracledb, etc. Maybe having a file per table instead of per database is easier to set up, but it might be just as hard, and doing IO on multiple files might be bad for performance.
