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
