Welcome to the MongoDB Playground!
We understand that learning a new technology can be daunting, but with the MongoDB Playground, we make it easy for you. Our playground comes pre-installed with MongoDB and is ready to use, allowing you to focus on learning and experimentation with a sample database. You don't have to go through the hassle of setting up your own environment.
So, why wait? Start playing with MongoDB today!
MongoDB is a type of NoSQL database that uses a document-oriented data model. This means that data is stored in "documents" which are similar to JSON objects and can have different fields, or keys, within each document. This is in contrast to a relational database, such as MySQL, which stores data in tables with fixed columns and rows.
For example, let's say we are building a social media application and we want to store user information in a MongoDB database. Each user would be represented as a separate document in the "users" collection. Each document could have fields such as "username", "password", "email", "age", and "friends". The "username" and "password" fields would be required for all documents, but the "age" field could be made optional, so it's not a problem if it's missing from some documents. This flexibility allows for easy modeling of complex and hierarchical data structures.
Additionally, MongoDB is a distributed database, which means that data can be stored across multiple servers, making it more scalable and fault-tolerant. As the amount of data stored in the database grows, more servers can be added to the cluster to handle the increased load. Moreover, MongoDB automatically maintains multiple copies of the data, so if a server or disk fails, the data remains safe and available on the other servers. This is useful for applications that need to handle a large amount of data or a high number of read/write operations.
The playground comes pre-installed with a command line and a sample database (called "movies") already loaded. You can use the MongoDB Shell, available via the command line, to test your queries and operations directly with the database.
In addition, the playground provides a Web-UI for MongoDB, which you can access by clicking on the Web-UI link provided at the top-right of the command line.
Please note that you can use the playground for 1 hour. If required, you can extend the usage by 15 minutes by clicking on the icon next to the timer icon.
