Symfony with mongo and mysql. Yes, but why?

Symfony with MongoDB AND MySQLYes, but why?!

wealth management, set free

Symfony● Stable● Plenty of Resources● Interoperability● Open Source● + Doctrine!

Doctrine● Decoupled from Symfony and

optional● DB connections setup in

parameters.yml● Doctrine MongoDB Bundle ● Doctrine Fixtures Bundle

integrated in Symfony standard edition

From http://symfony.com/doc/current/book/doctrine.html

A tale of two layers

wealthbot/app/config/config.yml

A tale of two layersMySQL = presentation

● Relational● Table● Vertical Scaling● Normalization: make tables as small as

possible (ex: user table)● PAS normalizes to MySQL

Mongo = communication

● Non-relational / NoSQL● Key - value pairs (JSON/BSON)● Horizontal scaling● Denormalization: to quickly get all the data● Standardize into mongo ● Do pre-calcs in mongo (bc it’s faster)

“Makes coding life easier, but must know the structure ahead of time”

“We don't know what the data file will look like from custodians”

MongoDBBundle

● Deal only with plain PHP objects

● Persist transparently to and from MongoDB

● Mapping via DocBlock annotations{

"require": { "doctrine/mongodb-odm": "~1.0", "doctrine/mongodb-odm-bundle": "~3.0" },}

Fixtures Bundle

● Fixtures are PHP classes● Load a controlled set of data● Used for testing or could be the

initial data● Shares Objects between

Fixtures● (enable in app/AppKernal.php)

$ composer require --dev doctrine/doctrine-fixtures-bundle

Exampleswealthbot/src/Wealthbot/FixturesBundle/DataFixtures/ORM/LoadClientData.php

class LoadClientData extends AbstractFixture implements OrderedFixtureInterface, ContainerAwareInterface {

private $accounts = array( array( 'consolidator_key' => null, 'group_key' => AccountGroup::GROUP_DEPOSIT_MONEY, 'type_key' => 10, 'financial_institution' => null, 'value' => 20000, 'monthly_contributions' => null, 'monthly_distributions' => null, 'sas_cash' => 1500, ), ...

Examples cont.wealthbot/src/Wealthbot/FixturesBundle/DataFixtures/ORM/LoadClientData.php

private function createClientAccounts(ObjectManager $manager, User $clientUser) { foreach ($this->accounts as $index => $item) {

$account = new ClientAccount(); $account->setGroupType($groupType); $account->setClient($clientUser); $account->setMonthlyDistributions($item['monthly_distributions']); $account->setSasCash($item['sas_cash']); $accountOwner = new ClientAccountOwner(); $accountOwner->setAccount($account); $accountOwner->setClient($clientUser); $accountOwner->setOwnerType(ClientAccountOwner::OWNER_TYPE_SELF);

}}

Why not just mongo?

● Cleaner code● More predictable = better unit

testing● Faster dashboards● And yet, flexible enough when

working with custodians
