<p>Kalau anda sudah terbiasa memakai database relasional seperti MySQL mungkin diperlukan sedikit perubahan <em>mindset</em> untuk mengenal tipe database yang namanya <strong>NoSQL</strong>. Seperti arti dari namanya, database ini merupakan database yang tidak memakai bahasa SQL query data tapi bisa secara langsung menggunakan bahasa pemrograman client sebagai contoh adalah <a href="https://www.mongodb.org/" target="_blank">MongoDB</a>.</p>
<p>Database <strong>NoSQL</strong> seperti MongoDB menyimpan data sebagai dokumen yang <em>schema-less</em> yang artinya yaitu data yang disimpan mempunyai <em>key - value</em> yang tidak terikat atau bebas. Anda bisa membayangkannya sebagai data JSON yang tersimpan di database.</p>
<p>Klien bisa berinteraksi langsung dengan database MongoDB dengan menggunakan shell JavaScript <code>mongo</code> untuk administrasi dan query data. Sebagai contoh jika kita ingin membuat sample data sebanyak 100 di <strong>collection</strong> <code>sample</code> maka perintah dalam shell adalah seperti berikut,</p>
<pre><code>$ mongo
MongoDB shell version: 2.6.9
connecting to: test
> use sample;
switched to db sample
> for(var i=0; i<100; i++){ db.sample.insert({band:"Dewa "+i})};
WriteResult({ "nInserted" : 1 })
> db.sample.count()
100
> db.sample.find();
{ "_id" : ObjectId("55cf520e2dd317a13673d11b"), "band" : "Dewa 0" }
{ "_id" : ObjectId("55cf520e2dd317a13673d11c"), "band" : "Dewa 1" }
{ "_id" : ObjectId("55cf520e2dd317a13673d11d"), "band" : "Dewa 2" }
{ "_id" : ObjectId("55cf520e2dd317a13673d11e"), "band" : "Dewa 3" }
{ "_id" : ObjectId("55cf520e2dd317a13673d11f"), "band" : "Dewa 4" }
{ "_id" : ObjectId("55cf520e2dd317a13673d120"), "band" : "Dewa 5" }
{ "_id" : ObjectId("55cf520e2dd317a13673d121"), "band" : "Dewa 6" }
{ "_id" : ObjectId("55cf520e2dd317a13673d122"), "band" : "Dewa 7" }
{ "_id" : ObjectId("55cf520e2dd317a13673d123"), "band" : "Dewa 8" }
{ "_id" : ObjectId("55cf520e2dd317a13673d124"), "band" : "Dewa 9" }
{ "_id" : ObjectId("55cf520e2dd317a13673d125"), "band" : "Dewa 10" }
{ "_id" : ObjectId("55cf520e2dd317a13673d126"), "band" : "Dewa 11" }
{ "_id" : ObjectId("55cf520e2dd317a13673d127"), "band" : "Dewa 12" }
{ "_id" : ObjectId("55cf520e2dd317a13673d128"), "band" : "Dewa 13" }
{ "_id" : ObjectId("55cf520e2dd317a13673d129"), "band" : "Dewa 14" }
{ "_id" : ObjectId("55cf520e2dd317a13673d12a"), "band" : "Dewa 15" }
{ "_id" : ObjectId("55cf520e2dd317a13673d12b"), "band" : "Dewa 16" }
{ "_id" : ObjectId("55cf520e2dd317a13673d12c"), "band" : "Dewa 17" }
{ "_id" : ObjectId("55cf520e2dd317a13673d12d"), "band" : "Dewa 18" }

<p>Sebelum kita lanjutkan ke koneksi Node.js dan MongoDB, perlu di ingat beberapa konsep penting dari MongoDB </p>
<h3 id="collection">Collection</h3>
<p><strong>Collection</strong> adalah kumpulan dari <strong>document</strong>, analoginya walaupun kurang tepat sebenarnya bisa dibilang seperti tabel kalo dalam database relasional.</p>
<h3 id="document">Document</h3>
<p><strong>Document</strong> itu sendiri adalah data yang tersimpan di database NoSQL dan didefinisikan oleh yang namanya <strong>Schema</strong>.</p>
<h3 id="schema">Schema</h3>
<p>Sebelumnya di katakan bahwa NoSQL menyimpan data yang <em>schema-less</em>, memang benar tapi tetap untuk menyimpan suatu dokumen di database biasanya aplikasi bekerja dengan model data tertentu misalnya untuk data <code>Person</code> bisa mempunyai <em>key - value</em> seperti berikut</p>
<pre><code>{
nama: "Kebo Ijo",
email: "[email protected]",
username: "obek_seloso"
}
</code></pre>
