API initializes sequence by filesys.dll

According to MSDN, here are the APIs initialized by filesys.dll in sequence:

1. Database APIs
   
2. File system APIs
   
3. Point-to-Point message queue APIs
   
4. Event log APIs
   
5. Registry APIs
   

I had not read the detail yet, but I am surprising the database API initialed before file system. The database does not need to refer to file system??
