Introduction with Sample Code: Database


PStore: the simplest OO database

    db = PStore.new("/tmp/foo")     # open database
    db.transaction do               # begin transaction
      p db.roots                    # dislay roots
      ary = db["root"] = [1,2,3,4]  # add to root
      ary[0] = [1,1.5]              # modify object
    end                             # end transaction

    db.transaction do               # begin transaction again
      p db["root"]                  # get root information
    end

We also have PostgreSQL,MySQL,Interbase interface,
plus Ruby/DBI database abstraction layer
