Developing Applications with MongoDB Java Integration

Databases are the workhorses for the modern information age. Like Atlas, they go largely unnoticed in supporting the digital world we’ve come to inhabit. It’s easy to forget that our digital interactions like commenting, tweeting & searching are in essence, interactions with a database.

Today, database has taken many forms – right from managing structured to unstructured data. Many modern applications are primarily web-based which require a scalable database for managing different types of data like email, logs, images, texts and video files.

MongoDB is a database management system designed for web applications and Internet infrastructure. It is built for high read and write throughput and has the ability to scale up easily. Whether an application requires just one database node or dozens of them, MongoDB provides better stability and performance compared to SQL databases.

Java, on the other hand, is one of the most popular software design languages used by developers. To create and deploy scalable applications leveraging Java development services, it is very important to integrate MongoDB with Java technology.

• Data is stored in the form of JSON style documents
• Easy indexing for any attribute
• Auto-Sharding helping to execute Rich Queries
• Faster CURD (Create, Update, Read, Delete) operations

The MongoDB command shell is a JavaScript-based tool that administers the database and updates data. The mongo executable loads the shell and connects to a specified mongod process. For instance, you can pick your database and then insert a simple document into the users collection like:

use mongodb-in-action
db.users.insert({name: “Kyle”})

The first command, that indicates which database you want to use, will be familiar to database users of MySQL. The second command is a JavaScript expression that inserts a simple document.

We will use Java MongoDB Driver for integration. MongoDB officially provides this driver with an extensible Codec API that allows applications to encode and decode their own classes directly to and from BSON; a new CURD API, based on the cross-driver CURD specification.

To use the driver, include the code below into your build.
