About Cena

For each entity object, Cena represent it the following in text:, _(*4)

• lifecycle (how it is generated),
• its properties, and
• relation with other entities.

Cena will simplifies various operations such as database synchronization and complicated html forms., _(*5)

Entity State and Text Representation

Given that the class name of entities are "Model"., _(*6)

An entity is represented as a simple text, called CenaID. For instance: Cena.model.new.1, Cena.model.get.1., _(*7)

Entity LifeCycles

Create a new entity of Model., _(*8)

// Cena.model.new.1
$entity = new Model();

Retrieve an entity from a database., _(*9)

$entity = Model::findById(1);
// Cena.model.get.1

Entity's Properties

To represent property values of an entity, just specify property name following the CenaID., _(*10)

Cena.model.new.1.prop.name = 'my name'
Cena.model.get.1.prop.name = 'your name'

Relation Between Entities.

Cena uses CenaID to represent relations between entities., _(*11)

Cena.model.new.1.link.related = Cena.other.get.1

The above simple notation is almost equivalent with the following PHP code., _(*12)

$entity = new Model();
$entity->setRelated( Other::findById(1) );

Protocol (tentative)

current protocol looks like:, _(*13)

{
  cenaID: {
    prop: { field1: value1, field2: value2, ... },
    link: { rel1: cenaID2, rel2: [ cenaID3, cenaID4,...],... }
    error: { field5: message5, field6: message6,... }
    info: {
      orig-cenaID: OriginalCenaId,...
    }
  }
}

Cena is Unique At...

So, what are the differences between Cena and other similar technologies? Honestly, I (the author) is not familiar with other technologies yet, so I cannot be certain but..., _(*14)

The following are (probably) the unique features of Cena., _(*15)

• easy to describe new entities (Cena.model.new.1).
• easy to manipulate many entities, new or existent.
• easy to relate new entities (i.e. no primary key) with other entities.

CenaManager

Currently, Doctrine2 can be used as a base ORM for Cena., _(*16)
