MONGODB COMPASS CREATE NEW DATABASE FULL VERSION

Compass: It is released as the full version of MongoDB Compass.

Compass Community: This edition is designed for developing with MongoDB and includes a subset of the features of Compass.MongoDB GUI is available in the following four editions: The source repositories of MongoDB compass can be found on the following link of GitHub When we explore exploring our data in the visual environment, we can use Compass GUI to optimize performance, manage indexes, and implement document-validation.Īll the versions of MongoDB Compass are opensource (i.e., we can freely deploy and view the repositories of all MongoDB GUI versions). MongoDB allows users to analyze the content of their stored data without any prior knowledge of MongoDB query syntax. Do you work with many database types? Navicat Premium 12.MongoDB Compass is a GUI for MongoDB. If you'd like to learn more about Navicat for MongoDB, please visit the product page.

MONGODB COMPASS CREATE NEW DATABASE MANUAL

Having said that, if you don't have documents referred to in multiple collections, I would recommend sticking with manual references. DBRefs are great for linking documents located in multiple collections with documents from a single collection.

MONGODB COMPASS CREATE NEW DATABASE HOW TO

In today's blog, we learned how to create DBRefs in MongoDB using Navicat for MongoDB.

MONGODB COMPASS CREATE NEW DATABASE CODE

Here's some code that dynamically looks in the collection specified by $ref parameter (address_home in our case) for a document with the id specified by the DBRef $id parameter: Now that we've updated our an employee document to use DBRefs, we will have to alter how we go about fetching the data from the employees collection.

Follow the same procedure for Barbara Palmer's second address, except this time, assign it a $ref of "address_work".

Here's the completed address_home DBRef:.

Once you're done adding the new fields, be sure to delete all of the existing address information from the document:.

Just copy it form the "135 Sycamore Dr." address document: You can located it in the addresses collection.

The DBRef requires the address document's $id field.

Expand the first address document and click on the plus (+) sign below the address fields to insert the three DBRef fields above:

Open her information in the Navicat Editor in "Tree View".

Let's modify Barbara Palmer's address information from last week's blog by removing the embedded fields and replacing them with DBRefs.

$db: This is an optional field and contains the name of the database in which the referenced document lies.

$id: This field specifies the _id field of the referenced document.

$ref: This field specifies the collection of the referenced document.

Whenever a document needs to reference documents from many collections, we should use DBRefs. Now, when a user collection's document references an address, it also needs to specify which collection to look up based on the address type. In cases where a document contains references from different collections, we can use MongoDB DBRefs.Īs an example scenario, where we would use DBRefs instead of manual references, let's consider a scenario where we are storing different types of addresses (home, office, mailing, etc.) in different collections (address_home, address_office, address_mailing, etc). Referenced Relationships are also often referred to as Manual References because we manually store the referenced document's id (or entire document) inside the other document. Comparing DBRefs to Referenced RelationshipsĪs we saw in last week's blog on MongoDB relationships, we can implement a normalized database structure in MongoDB by creating a Referenced Relationship. Today, we'll learn how to create DBRefs in MongoDB. We then gained some valuable experience with each by creating both an Embedded and Referenced relationship. In last week's blog, we explored the pros and cons of document relationship modeling via Embedded and Referenced approaches in MongoDB.
