NAME

ObjStore - Perl Extension For ObjectStore OODBMS

SYNOPSIS

The new SQL and the sunset of relational databases.

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.

INCLUDED TOOLS

• ospeek

  Prints out databases in Data::Dumper style.

• posh

  Like sh/csh, except that you can change directory 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 :-).

• osperlserver

  Run it against any database that inherits ObjStore::ServerDB and it will provide a remote method invokation service.

PREREQUISITES

You will need:

- ObjectStore OODBMS (see http://www.odi.com; evaluations are available!)

- Perl 5.004_04 (or perl 5.005, once released)

- Tree::Fat & Test perl extensions

- ExtUtils::ExCxx (only needed on Digital UNIX, HP (5.x), OS/2 (3.x), or MS Windows NT/95; send email)

See http://www.perl.com/CPAN/authors/id/JPRIT/ !

################## # RECENT CHAN@ES # ##################

** 03-21-98 RELEASE 1.32

- Major improvements to serverization code. See osperlserver, ObjStore::ServerDB, and ObjStore::Process. It is likely that not all changes are backward compatible to 1.30 (but I'm pretty sure improvements will outweigh breakage :-).

- ObjStore::AV::Set now checks for duplicates.

** 03-13-98 RELEASE 1.31

- Posh will move directly to a database specified on the command line. Also, the default is now mvcc mode. Fixed a problem with persisting command history.

- Changed the behavior ObjStore::AV::Set::exists(...) to be more consistent.

- Fixed a problem in the is_evolved() method.

- $ObjStore::TRANSACTION_PRIORITY is now a tied scalar.

- Replaced (get|set)_(read|write)lock_timeout (yikes!) with a single perl-style lock_timeout API.

- Reorganized the BOOT section to meet the requirements of the perl compiler. ObjStore::shutdown is now called in an END block to insure proper clean up (abort pending transactions, etc.) and initialization is now delayed until run-time (vs. compile-time).
