Document-oriented databases store data in collections of documents rather than tables with a predefined schema. MongoDB is an open-source, document-oriented database that is easy to install and use. It supports many programming languages and operating systems. Documents in MongoDB can have unique field sets and storing non-normalized data can provide faster speeds than relational databases for heavy use cases.

5. MongoDB BasicsBasic commandsList databases: show dbsSelect database: use [db name]Insert documentdb.myCollection.insert({‘myKey’ : ‘myValue’, ‘anotherKey’ : ‘anotherValue’ })John Sercel | 5

6. MongoDB BasicsSelect documents (MongoDB)db.myCollection.find()db.myCollection.find({‘name’ : ‘John Doe’})Select documents (SQL)SELECT * FROM myTable SELECT * FROM myTable WHERE name = ‘John Doe’John Sercel | 6

8. Connecting MongoDB: PHPPHP ExampleInsert new document $connection = new Mongo(); $collection = $connection->databaseName->collectionName; $document = array( "name" => “John Doe”); $collection->insert($document);Select document(s) $documents = $collection->find();John Sercel | 8

9. Why Document-Oriented?Storing unique documentsNon-standard field set in each entitySpeed vs. NormalizationNormalization decreases redundancy, and speed.Relational operations are expensiveSimple data storage preferable for heavy useBigTable, CassandraJohn Sercel | 9
