Then we can execute the DeleteOneAsync method to delete the first one, and finally check how many items have been deleted by accessing the properties exposed by the DeleteResult object. Public class Game Īs usual, to find the items to be deleted we must create the correct FilterDefinition.

The class we're going to use is called Game, and has a simple definition:

To use the C# driver you must install some NuGet packages: MongoDB.Driver, and MongoDB.Bson. Time to run some queries! Setting up the project Of course, you can use other tools like NoSQLBooster for MongoDB and Robo 3T or simply rely on the command prompt. In the image below you can see the host-database-collection-document structure as displayed by MongoDB Compass. In this article, I'm going to use MongoDB Compass Community, a tool provided directly by MongoDB. Of course, you can use different applications to navigate and interact with MongoDB databases. You can structure your hosts to replicate data to split the load between different nodes.įor this article, since I'm going to run MongoDB using Docker, you'll see that my host is on localhost:27888 (again, to see how I set up the port, have a look at my other article). On the contrary of real files, documents have no name.ĭocuments are grouped in collections: they are nothing but a coherent grouping of similar documents you can think of them as they were folders.Īll the collections are stored within a database on which you can apply security rules, perform statistical analysis, and so on.įinally, of course, all databases will be stored (and exposed) on a host: it's the endpoint reachable to perform queries. Documents can be queried by referencing the field names and by applying filters and sorting. The base structure is the document: here you'll store the JSON structure of your data, with all the nested fields.

If you want to try MongoDB on your local machine, you can download the Community Edition from the project website and install it with a few clicks. NET, you might want to use the official MongoDB driver for C#. You can also have nested information within the same document, for example, the address, info of a user.īeing based on JSON files, you can query the documents using JS-like syntax.īut if you are working with. You don't have a strict format as you would have with SQL databases, where everything is defined in terms of tables and columns on the contrary, you have text documents that can be expanded as you want without changing all the other documents. MongoDB is one of the most famous document database engine currently available.Ī document database is a kind of DB that, instead of storing data in tables, stores them into JSON-like documents.
