db.apps.insert({_id:1, label:"Torch", color:"Red", available:false})
db.apps.insert({_id:2, label:"Decode", color:"Red", available:false})
db.apps.insert({_id:3, label:"PadLock", color:"Orange", available:false})

See the content of the collection

db.apps.find()
{_id:1, label:"Torch", color:"Red", available:false}
{_id:2, label:"Decode", color:"Red", available:false}
{_id:3, label:"PadLock", color:"Orange", available:false}

Add a property to a document

db.apps.update({label:"Torch"}, {$set: {tab:["A","B","C"]}})

Edit a property in multiple documents

db.apps.update({available:false}, {$set: {available:true}}, {multi:true})

View table contents in descending order

db.apps.find({label: {$in: ["Torch","Decode","PadLock"]}}).sort({_id:-1})
{_id:3, label:"PadLock", color:"Orange", available:true}
{_id:2, label:"Decode", color:"Red", available:true}
{_id:1, label:"Torch", color:"Red", available:true, tab:["A","B","C"]}

Add a value to an array

db.apps.update({label:"Torch"}, {$push: {tab:"D"}})

Add the same value in an array without duplicate

db.apps.update({label:"Torch"}, {$addToSet: {tab:"D"}})

View the element owning the array properly

db.apps.find({label:"Torch"}).pretty()
{
     _id:1,
     label:"Torch",
     color:"Red",
     available:true,
     tab:[
         "A",
         "B",
         "C",

     ]
}

Delete a property in a document

db.apps.update({label:"Torch"}, {$unset: {tab:1}})

Delete a document from a collection

db.apps.remove({label:"Torch"})

Delete a collection
