NAME

CogBase - A CogBase Implementation in Perl

WARNING

This Database implementation is in its infancy. Just barely a proof of concept so far. It would be ridiculous of you to use it for anything serious, yet.

SYNOPSIS

use CogBase;

my $conn = CogBase->connect('http://cog.example.com');

my $schema = $conn->node('Schema');
$schema->value(<<'...');
+: person
<: Node
age: Number
given_name: String
family_name: String
...
$conn->store($schema);

my $person = $conn->node('person');

$person->given_name('Ingy');
$person->family_name('dot Net');
$person->age(42);

$conn->store($person);

my @results = $conn->query('!person');
my @nodes = $conn->fetch(@results);

for my $node (@nodes) {
    print "%s %s is %d years old\n",
        $node->given_name,
        $node->family_name,
        $node->age;
}

$conn->disconnect;

DESCRIPTION

CogBase is a Object Database Management System.

Some interesting characteristics of its design are:

  • All objects are stored as nodes.

  • Every node has a universally unique id.

  • Every node has a type.

  • Every type has a schema.

  • Every schema, is itself, a node in the db.

  • Every schema has a base/super schema that it inherits from.

  • Schemas can be used to generate programming language (Perl) classes for every type (schema) of node.

  • CogBase defines several core scalar types.

  • CogBase defines one core schema (that every schema inherits from).

  • Every node has one or more revisions.

  • Every revision is immutable.

  • Database access methods are connect, create, store, fetch, query and disconnect.

  • All nodes have access control based on the Unix File System.

  • HTTP is used for the network layer. GET and POST are used for all operations.

  • Database can be used over network or embedded.

  • Access control is based on Unix File System
