Question

MongoDB is commonly used in the LMS Moodle. Why is this database a preferred choice for this type of system?

Answer 1

• Moodle is an open source LMS (Learning management system).
• MongoDB is mainly used as a caching system in Moodle LMS.
• MongoDB is simple and can be easily installed on such systems.
• MongoDB is commonly used because it can be used to handle Moodle sites with multiple servers.
• In Moodle there is a caching plugin framework, using this we can control where the cached data is stored.
• MongoDB helps better in making a easy scalable model.
• This database is a schema less database.
• It is a NoSQL database.
• Here the data is stored in the database in the form of JSON.
• Mapping of application objects to data objects are no more needed.
• It is highly secure than other databases, because here no SQL injection can be done.
• It does not require a virtual machine.
• We can search in the database using fields and regex.
• It has the ability to store the data in different machines, this is called sharding.
• Using sharding it can ensure the horizontal scaling , means when there is a growth in data it can increase the storage by storing data in different machines.
