The community database is the foundation for a set of applications that will serve the wireless community. The primary focus is a The database is currently implemented in SQL tables on postgresql.

DonPark and AdamShand are thinking about ways to create a SQL (or maybe LDAP or XML or something) schema which a community wireless group can use as a universal data collection point. We're trying to catalog everything we can think of that a community wireless group would want to keep track of (yes we know we're doomed to failure :-).

  • Don, it occurred to me that it might be worth checking out the NoCatAuth SQL schema (etc/nocat.schema in the tarball), they had originally planned for it to be more then just the auth server. -- Adam. I looked it over. added bandwidth and date to Node. Created Network. added URLs and password to User. (8Jun) -- DonPark

    How would the local *Cat box regulate bandwidth to the user? Would the local *Cat box have a table with users and their respective classes (owner, member, guest, etc..), or would there be another table for that? Somehow we have to account for the bandwidth shaping aspect of things. We could add a field of Type STATUS, memberstatus (nodeOwner, fullMember, guest), and have the local node shape bandwidth for those values. Make sense? -- DanRichardson

community database take two. March 2003 AdamShand, JerrittCollord, AaronBaer, (insert your name here)

I pulled this right out of postgresql since it doesnt appear to be documented anywhere else -- DonPark
