Global Database

[slacker]

I was thinking about implementing a database that contained all sorts of data like the Windows Registry. How could i make this database available to all apps that would run on my OS?

Well, you could store the database in a well known place (e.g. "/database" or "C:\System\DataBase32"). Every app could then OPEN this file.

You could provide system calls to set and retrieve information.

i want to put this data in memory because disk is too slow....but how would an APP know how to reference the data..?

make an public API that your apps call..

or use interbase, and have your apps link against the interbase library

i want to put this data in memory because disk is too slow....but how would an APP know how to reference the data..?

What i have is:

Code: Select all

lookup(<location>.*) --> returns an enumeration of all the keys under <location>
lookup(<location>.<key>) --> returns the value of a key
register(<location>.<key>,<value>) --> adds the key, value pair in the DB.

So the application knows it is looking for "system.device.disk.ide0.master.ID" and the database uses that name to retrieve the final information (in this case, an int) and returns it...
