=head1 NAME
ObjStore - Perl Extension For C<ObjectStore> OODBMS
=head1 SYNOPSIS
Enjoy perl? Sick of SQL? Ready to try something new?
=head1 DESCRIPTION
ObjectStore is the market leader in object-oriented databases
http://www.odi.com (NASDAQ: ODIS). They use a unique Cache-Forward
Architecture to make persistent data available in literally the most
efficient manner possible.
Prior to this joining of forces: ObjectStore was too radical a design
decision for many applications; and perl5 did not have a simple way of
storing complex data persistently. Now there is an easy way to build
database applications, especially if you are concerned about
preserving your ideals of encapsulation.
=head2 INCLUDED TOOLS
=over 4
=item * ospeek
Prints out databases in Data::Dumper style.
=item * posh
Like C<sh>/C<csh>, except that you can I<change directory> B<into>
your database and walk around the data from the inside. You can also
invoke methods on your objects or write custom reports (in perl, of
course :-).
=item * osperlserver
Provides remote method invokation, database job scheduling, and
server-object collaboration services. Completely generic.

# RECENT CHAN@ES #
##################
** 04-06-98 RELEASE 1.34
- Another read-only mode is available for ObjStore::Index. A
distinction is made between exclusive and shared read-only keys.
The default mode has been changed to _exclusive_ read-only.
Also added support for shift and pop.
- Delay object destruction with ObjStore::Mortician. Also, general
improvements to the serverization modules.
- Optimized typemap slightly. Also fixed typemap bugs in
ObjStore::Index::seek & ObjStore::Index::configure. Optimized
reallocation of (persistent) memory in string assignments.
- Overloaded == & != operator tests no longer work if either argument
is non-persistent. While this breaks backward compatiblility, I
believe the extra strictness is worth it.
- The automatic safe_require code was apparently a bit _TOO_ safe.
Exceptions were been hidden! Fixed.
- Improved Digital AXP hints.
** 03-28-98 RELEASE 1.33
- Stringification of persistent objects can no longer cause
ObjectStore exceptions. Error reporting is therefore much more
robust.
- Use ObjStore::NoInit to delay initialization of the ObjectStore
library. This opens time to modify configuration parameters (or
for forking) before becoming a known OS client.
- First-cut at database job scheduling. See ObjStore::Job!
- Blessings were not sticking to databases in certain cases. Fixed.
