![]() ![]() The other one is the Graphical User Interface (GUI) that allows users to communicate with the MongoDB Server through automated tool functions rather than command-line queries. The first one is the Mongo shell, which is the simple command-line interface of the MongoDB server. MongoDB allows users to interact with the MongoDB Server through two interfaces. MongoDB environment provides a MongoDB Server to start and create several databases. Consequently, MongoDB is called a schema-less database. Each document in the MongoDB Collection is different due to its unstructured format. The data in MongoDB is referred to as Documents, whereas the number of Documents is called a Collection. Since it is an unstructured database, it has a flexible data structure that makes it easier to use for systems with a large volume of data and high performance. MongoDB is an open-source unstructured database that allows users to store data in key-value pairs, making it easy to access. ![]() Update and Delete Documents in MongoDB Compass.Create a Database and Insert Data in MongoDB Compass.In contrast, in MongoDB Compass, users can visualize their database and its modifications without worrying about the performance. Further, the MongoDB Shell works on the database on its own, and users cannot analyze and see the data changes independently. The speed of the MongoDB Shell can decrease while processing massive data. Besides, it becomes complex to query extensive volume data in the command-line interface. To mitigate such challenges, organizations can leverage MongoDB Compass, a Graphical User Interface solution that can assist any user in Creating, Inserting, Updating, Filtering, and even Deleting the documents visually with a click of the buttons. D) Update and Delete Documents in MongoDB Compass.C) Create a Database and Insert data in MongoDB Compass.Simplify your MongoDB ETL with Hevo’s No-code Data Pipeline.In this case you can simply set a filter on the property_type field that is equal to the requested value. Suppose you want to extract all properties of type “House” from the AirBnB database. Information about the indexes defined for the selected collection is also shown. The other 3 menus ( Explain Plan, Indexes and Validation) will not be used in this tutorial, but are used, as you can see from their names, respectively to analyze the execution plan of a query, manage indexes and insert validation rules for the documents stored in the collection.įinally, in the upper right part of the screen some information about the number of comments saved, the space occupied both by the collection and on average by each document is always displayed. Next we’ll see how to use it to understand which queries can return results of interest. The Schema menu is used to analyze the schema of the data in the collection and retrieve some statistics about the distribution of the data. ![]() The second menu is related to aggregation pipelines and is used for more complex queries that require transformation operations of the data present in the documents. Also, if there is any syntax error the badge next to the form field will have a red colored background. As you type, in fact, MongoDB Compass will suggest the fields and operators that might be useful to compose the query. Very useful features of the query form are the auto-completion and the syntax validation. To enter all these options, simply expand the query form by clicking on the OPTIONS button. It is possible to insert filters, projections, sort conditions and limitation of the number of records returned. For each document displayed, you can edit it, copy it to your clipboard, duplicate it and delete it using the buttons on the right associated with each document.Īs mentioned earlier, this screen can be used to query the collections. The other views are the JSON (available since version 1.2) and the tabular view. If there are complex structures within a document (embedded documents, arrays) it is possible to expand them to display the data present. ![]()
