Learn MongoDB sorting and limiting Tutorial for Beginners video 4
Sorting is one of the necessary database operations. It helps to simplify readability and sort the data as per the requirement. In this video, you will learn about the sorting concept and how it can be implemented in the MongoDB database.
Sorting can be defined as the ordering of data in an increasing as well as decreasing manner based on some linear relationships among the various data items residing in the database. Sorting can be performed on entities like information (which includes names and facts), numbers as well as records. Sorting also increases the readability and uniformity of the displayed data from the database.
MongoDB allows you to specify the maximum number of documents to return by making use of the limit() method which will return only the number of documents you need. And as soon as you prepare a MongoDB query for the collection with the help of db.collection.find() method, you can add on the limit() method for specifying the limit.
