Some inital thoughts how the database should work
Some commands to implement:

sdb insert auto,tiny,bla,bla
sdb insert in TABEL=BOOKS id=auto,title=test,author=bla

sdb get all from books sort asc by author
sdb get all from books where author=bla sort asc by id
sdb get first 10 
sdb get last 10 

#if a field contains linebreaks escape them
#a file can contain different tables
#relations are defined in the header of the table definition
