Editing a collection
db.collection.update(query, update) query: An object for finding the document Example: {"name":"shilpi"} update: An object for updating the document with set command Example: {$set:{"age":"23"}}
To edit a mongodb collection update function is used
Apply the query for finding the document which you want to update. In our collection we want to update collection having name as shilpi so query is:
{"name":"shilpi"}
Using the set command to modify the Field Name
Choose which Field Name you want to modify and then enter the new value accordingly into the query. In our collection we want to edit age value to 23 for name shilpi:
{$set:{"age":"23"}}
Defining, Creating and Dropping a MongoDB collection
MongoDB, the most popular NoSQL database, is an open-source document-oriented database. The term ‘NoSQL’ means ‘non-relational’. It means that MongoDB isn’t based on the table-like relational database structure but provides an altogether different mechanism for storage and retrieval of data.
