ObjStore::ServerDB - Generic Real-Time Database Server Framework

    osperlserver host:/full/path/to/db+=MyClass

An active database is an framework for tightly integrated collaboration. While implementation abstraction is preserved without hinderance, objects can easy interact in a variety of ways:

* ABSTRACTION / COLLABORATION

The hash at the top of the database holds the set of cooperating objects that implement all database functionality. This hash is always accessable via $any-database_of->hash>. Furthermore, keys are populated such that they reflect the @ISA tree of object instances.

* CLIENT / SERVER

Other processes can read the database asyncronously with MVCC transactions invoke remote method invokations (RMIs) on individual objects. See ObjStore::notify.

* EVENT MANAGEMENT

The Event API is fully integrated (see ObjStore::Process). Moreover, low priority jobs can be (persistently) queued for processing with a variety of scheduling options (see ObjStore::Job).

The $db-hash->do_boot_class> method creates arbitrary classes and populates the top-level hash. There are quite a few ways to invoke it:

* COMMAND-LINE

  osperlserver host:/full/path/to/db+=MyClass

* RMI

  $db->hash->boot_class('MyClass');

* INHERITANCE

  package MyDB::Top;
  require 'ObjStore::ServerDB';
  use base 'ObjStore::ServerDB::Top';
  sub boot {
     my ($o) = @_;
     $o->boot_class('MyClass');
  }

  osperlserver host:/full/path/to/db=MyDB
