Mongo
                       Mongo as in "humongous". Used to describe
                       something extremely large or important.

MongoDB is a scalable, high-performance,
            open source NoSQL database.

    - Document Oriented DB
    - Written in C++
    - Available for *nux (Linux, Solaris, etc),
       Windows and OS X
    - Lots of Drivers (PHP, Java, Python, Ruby...)




Friday, May 18, 2012
Features

          - Flexible JSON-style documents
          - Full Indexing
          - Complex Queries / Map Reduce
          - Aggregation Framework (coming soon)
          - GridFS (store files natively)
          - Multiple Replication Options
          - Sharding
          - Simple Installation / Zero Config




Friday, May 18, 2012
Document Oriented


 Coming from SQL?




                             Database => Database
                             Table => Collection
                             Row => Document




Friday, May 18, 2012
JSON-style documents
    {
         name: {
                   first: 'John',
                   last: 'Doe'
                  },
         title: 'Engineer',
         age: 40
  }




Friday, May 18, 2012
No Schema or fixed tables

     {
          name: {
                    first: 'Foo',
                    last: 'Bar'
                   },
          title: 'Student',
          school: 'Harvard'
  }

Full Indexing



                  db.coll.ensureIndex({name.last: 1})

                  db.coll.ensureIndex({name.first: 1, name.last: 1})

                  db.coll.ensureIndex({age: 0})




Friday, May 18, 2012
Querying



                       db.coll.find({name: 'John'})

                       db.coll.find({keywords: 'storage'})

                       db.coll.find({keywords: {$in: ['storage', 'DBMS']}}




Friday, May 18, 2012
GridFS




                       - Files are divided in chunks
                         and stored over multiple documents

                       - Transparent API

DoctrineMongoDBBundle
 Defining Documents




Friday, May 18, 2012
DoctrineMongoDBBundle
 Defining Documents
 // src/Acme/StoreBundle/Document/Product.php
 namespace AcmeStoreBundleDocument;

 use DoctrineODMMongoDBMappingAnnotations as MongoDB;

 /**
   * @MongoDBDocument(collection="product")
   */
 class Product
 {
      /**
       * @MongoDBId
       */
      protected $id;

            /**
             * @MongoDBString @MongoDBIndex(unique=true, order="asc")
             */
            protected $name;



Friday, May 18, 2012
DoctrineMongoDBBundle
 Using Documents
 // src/Acme/StoreBundle/Controller/DefaultController.php
 use AcmeStoreBundleDocumentProduct;
 use SymfonyComponentHttpFoundationResponse;
 // ...

 public function createAction()
 {
     $product = new Product();
     $product->setName('A Foo Bar');
     $product->setPrice('19.99');

            $dm = $this->get('doctrine.odm.mongodb.document_manager');
            $dm->persist($product);
            $dm->flush();

            return new Response('Created product id '.$product->getId());
 }




Friday, May 18, 2012
Forms
        Since Documents are Plain PHP Objects integrating it with Symfony Forms is straightforward.

   public function createAction()
   {
       $dm = $this->get
   ('doctrine.odm.mongodb.default_document_manager');

       $form = $this->createForm(new RegistrationType(), new
   Registration());

             $form->bindRequest($this->getRequest());

             if ($form->isValid()) {
                 $registration = $form->getData();

                       $dm->persist($registration->getUser());
                       $dm->flush();

                       return $this->redirect(...);
             }
